Class Policies and Grading<br />

The students will receive a Unit Outline at the beginning of each Unit. It will have information<br />

about the assignments that they will do, what it’s grade classification will be, what action<br />

they will need to do to complete the assignment and when it is due.<br />

The students will receive a Weekly Memo of the activities they will be responsible for that<br />

week. It will serve to inform the students of the learning goal for the week. It will also give<br />

the students any special information about that week.<br />

The students will also receive daily lectures and assignments that are designed to teach and<br />

re-enforce information related to the learning goal. This will be time in which new material<br />

will be taught and reviewed and will give the students the opportunity to ask questions<br />

regarding the concepts being taught.<br />

The students will work with a Lab partner and also be in a Lab group, but it will be up to the<br />

individual student to do his or her part of all assignments and the individual student will<br />

ultimately be responsible for all information presented in the class.<br />

The students will be required to follow all District and School Policies and to follow all Lab<br />

Safety Procedures, which they will be given and will sign, while performing labs. Students<br />

should come to class on time and with the supplies needed for that class.<br />

The following grading policy will be used.<br />

Percent of Final Grade<br />

Notebook 40%<br />

Test/Projects 30%<br />

Labs/Quizzes 20%<br />

Work 10%<br />

The students will be given a teacher generated Mid Term and a District Final.

Chemistry Safety<br />

Safety in the MUSTANG LABORATORIES - Chemistry Laboratory<br />

Working in the chemistry laboratory is an interesting and rewarding experience. During your labs, you will be actively<br />

involved from beginning to end—from setting some change in motion to drawing some conclusion. In the laboratory, you will<br />

be working with equipment and materials that can cause injury if they are not handled properly.<br />

However, the laboratory is a safe place to work if you are careful. Accidents do not just happen; they are caused—by<br />

carelessness, haste, and disregard of safety rules and practices. Safety rules to be followed in the laboratory are listed<br />

below. Before beginning any lab work, read these rules, learn them, and follow them carefully.<br />

General<br />

1. Be prepared to work when you arrive at the lab. Familiarize yourself with the lab procedures before beginning the lab.<br />

2. Perform only those lab activities assigned by your teacher. Never do anything in the laboratory that is not called for in<br />

the laboratory procedure or by your teacher. Never work alone in the lab. Do not engage in any horseplay.<br />

3. Work areas should be kept clean and tidy at all times. Only lab manuals and notebooks should be brought to the work<br />

area. Other books, purses, brief cases, etc. should be left at your desk or placed in a designated storage area.<br />

4. Clothing should be appropriate for working in the lab. Jackets, ties, and other loose garments should be removed. Open<br />

shoes should not be worn.<br />

5. Long hair should be tied back or covered, especially in the vicinity of open flame.<br />

6. Jewelry that might present a safety hazard, such as dangling necklaces, chains, medallions, or bracelets should not be<br />

worn in the lab.<br />

7. Follow all instructions, both written and oral, carefully.<br />

8. Safety goggles and lab aprons should be worn at all times.<br />

9. Set up apparatus as described in the lab manual or by your teacher. Never use makeshift arrangements.<br />

10. Always use the prescribed instrument (tongs, test tube holder, forceps, etc.) for handling apparatus or equipment.<br />

11. Keep all combustible materials away from open flames.<br />

12. Never touch any substance in the lab unless specifically instructed to do so by your teacher.<br />

13. Never put your face near the mouth of a container that is holding chemicals.<br />

14. Never smell any chemicals unless instructed to do so by your teacher. When testing for odors, use a wafting motion to<br />

direct the odors to your nose.<br />

15. Any activity involving poisonous vapors should be conducted in the fume hood.<br />

16. Dispose of waste materials as instructed by your teacher.<br />

17. Clean up all spills immediately.<br />

18. Clean and wipe dry all work surfaces at the end of class. Wash your hands thoroughly.<br />

19. Know the location of emergency equipment (first aid kit, fire extinguisher, fire shower, fire blanket, etc.) and how to use them.<br />

20. Report all accidents to the teacher immediately.<br />

Handling Chemicals<br />

21. Read and double check labels on reagent bottles before removing any reagent. Take only as much reagent as you need.<br />

22. Do not return unused reagent to stock bottles.<br />

23. When transferring chemical reagents from one container to another, hold the containers out away from your body.<br />

24. When mixing an acid and water, always add the acid to the water.<br />

25. Avoid touching chemicals with your hands. If chemicals do come in contact with your hands, wash them immediately.<br />

26. Notify your teacher if you have any medical problems that might relate to lab work, such as allergies or asthma.<br />

27. If you will be working with chemicals in the lab, avoid wearing contact lenses. Change to glasses, if possible, or notify<br />

the teacher.<br />

Handling Glassware<br />

28. Glass tubing, especially long pieces, should be carried in a vertical position to minimize the likelihood of breakage and<br />

to avoid stabbing anyone.


29. Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Dispose of the<br />

glass as directed by your teacher.<br />

30. Always lubricate glassware (tubing, thistle tubes, thermometers, etc.) with water or glycerin before attempting to insert it into a<br />

rubber stopper.<br />

31. Never apply force when inserting or removing glassware from a stopper. Use a twisting motion. If a piece of glassware<br />

becomes "frozen" in a stopper, take it to your teacher.<br />

32. Do not place hot glassware directly on the lab table. Always use an insulating pad of some sort.<br />

33. Allow plenty of time for hot glass to cool before touching it. Hot glass can cause painful burns. (Hot glass looks cool.)<br />

Heating Substances<br />

34. Exercise extreme caution when using a gas burner. Keep your head and clothing away from the flame.<br />

35. Always turn the burner off when it is not in use.<br />

36. Do not bring any substance into contact with a flame unless instructed to do so.<br />

37. Never heat anything without being instructed to do so.<br />

38. Never look into a container that is being heated.<br />

39. When heating a substance in a test tube, make sure that the mouth of the tube is not pointed at yourself or anyone else.<br />

40. Never leave unattended anything that is being heated or is visibly reacting.<br />

First Aid in the MUSTANG LABORATORIES - Chemistry Laboratory<br />

Accidents do not often happen in well-equipped chemistry laboratories if students understand safe laboratory procedures<br />

and are careful in following them. When an occasional accident does occur, it is likely to be a minor one.<br />

The instructor will assist in treating injuries such as minor cuts and burns. However, for some types of injuries, you must take<br />

action immediately. The following information will be helpful to you if an accident occurs.<br />

1. Shock. People who are suffering from any severe injury (for example, a bad burn or major loss of blood) may be in a state<br />

of shock. A person in shock is usually pale and faint. The person may be sweating, with cold, moist skin and a weak, rapid<br />

pulse. Shock is a serious medical condition. Do not allow a person in shock to walk anywhere—even to the campus security<br />

office. While emergency help is being summoned, place the victim face up in a horizontal position, with the feet raised about<br />

30 centimeters. Loosen any tightly fitting clothing and keep him or her warm.<br />

2. Chemicals in the Eyes. Getting any kind of a chemical into the eyes is undesirable, but certain chemicals are especially<br />

harmful. They can destroy eyesight in a matter of seconds. Because you will be wearing safety goggles at all times in the lab,<br />

the likelihood of this kind of accident is remote. However, if it does happen, flush your eyes with water immediately. Do NOT<br />

attempt to go to the campus office before flushing your eyes. It is important that flushing with water be continued for a<br />

prolonged time—about 15 minutes.<br />

3. Clothing or Hair on Fire. A person whose clothing or hair catches on fire will often run around hysterically in an<br />

unsuccessful effort to get away from the fire. This only provides the fire with more oxygen and makes it burn faster. For<br />

clothing fires, throw yourself to the ground and roll around to extinguish the flames. For hair fires, use a fire blanket to<br />

smother the flames. Notify campus security immediately.<br />

4. Bleeding from a Cut. Most cuts that occur in the chemistry laboratory are minor. For minor cuts, apply pressure to the<br />

wound with a sterile gauze. Notify campus security of all injuries in the lab. If the victim is bleeding badly, raise the bleeding<br />

part, if possible, and apply pressure to the wound with a piece of sterile gauze. While first aid is being given, someone else<br />

should notify the campus security officer.<br />

5. Chemicals in the Mouth. Many chemicals are poisonous to varying degrees. Any chemical taken into the mouth should be<br />

spat out and the mouth rinsed thoroughly with water. Note the name of the chemical and notify the campus office<br />

immediately. If the victim swallows a chemical, note the name of the chemical and notify campus security immediately.<br />

If necessary, the campus security officer or administrator will contact the Poison Control Center, a hospital emergency room,<br />

or a physician for instructions.<br />

6. Acid or Base Spilled on the Skin.<br />

Flush the skin with water for about 15 minutes. Take the victim to the campus office to report the injury.<br />

7. Breathing Smoke or Chemical Fumes.<br />

All experiments that give off smoke or noxious gases should be conducted in a well-ventilated fume hood. This will make an<br />

accident of this kind unlikely. If smoke or chemical fumes are present in the laboratory, all persons—even those who do not<br />

feel ill—should leave the laboratory immediately. Make certain that all doors to the laboratory are closed after the last<br />

person has left. Since smoke rises, stay low while evacuating a smoke-filled room. Notify campus security immediately.


MUSTANG LABORATORIES<br />

COMMITMENT TO SAFETY IN THE LABORATORY<br />

As a student enrolled in Chemistry at Lorenzo Walker Technical High School, I agree to use<br />

good laboratory safety practices at all times. I also agree that I will:<br />

1. Conduct myself in a professional manner, respecting both my personal safety and the safety of others in the laboratory.<br />

2. Wear proper and approved safety glasses or goggles in the laboratory at all times.<br />

3. Wear sensible clothing and tie back long hair in the laboratory. Understand that open-toed shoes pose a hazard during<br />

laboratory classes and that contact lenses are an added safety risk.<br />

4. Keep my lab area free of clutter during an experiment.<br />

5. Never bring food or drink into the laboratory, nor apply makeup within the laboratory.<br />

6. Be aware of the location of safety equipment such as the fire extinguisher, eye wash station, fire blanket, first aid kit.<br />

Know the location of the nearest telephone and exits.<br />

7. Read the assigned lab prior to coming to the laboratory.<br />

8. Carefully read all labels on all chemical containers before using their contents, remove a small amount of reagent<br />

properly if needed, do not pour back the unused chemicals into the original container.<br />

9. Dispose of chemicals as directed by the instructor only. At no time will I pour anything down the sink without prior<br />

instruction.<br />

10. Never inhale fumes emitted during an experiment. Use the fume hood when instructed to do so.<br />

11. Report any accident immediately to the instructor, including chemical spills.<br />

12. Dispose of broken glass and sharps only in the designated containers.<br />

13. Clean my work area and all glassware before leaving the laboratory.<br />

14. Wash my hands before leaving the laboratory.<br />

Common Lab Equipment Uses


Significant Figures Rules<br />

There are three rules on determining how many significant figures are in a<br />

number:<br />

1. Non-zero digits are always significant.<br />

2. Any zeros between two significant digits are significant.<br />

3. A final zero or trailing zeros in the DECIMAL PORTION ONLY are<br />

significant.<br />

Please remember that, in science, all numbers are based upon measurements (except for a very few<br />

that are defined). Since all measurements are uncertain, we must only use those numbers that are<br />

meaningful.<br />

Not all of the digits have meaning (significance) and, therefore, should not be written down. In<br />

science, only the numbers that have significance (derived from measurement) are written.<br />

Rule 1: Non-zero digits are always significant.<br />

If you measure something and the device you use (ruler, thermometer, triple-beam, balance, etc.)<br />

returns a number to you, then you have made a measurement decision and that ACT of measuring<br />

gives significance to that particular numeral (or digit) in the overall value you obtain.<br />

Hence a number like 46.78 would have four significant figures and 3.94 would have three.<br />

Rule 2: Any zeros between two significant digits are significant.<br />

Suppose you had a number like 409. By the first rule, the 4 and the 9 are significant. However, to<br />

make a measurement decision on the 4 (in the hundred's place) and the 9 (in the one's place), you<br />

HAD to have made a decision on the ten's place. The measurement scale for this number would have<br />

hundreds, tens, and ones marked.<br />

Like the following example:<br />

These are sometimes called "captured zeros."<br />

If a number has a decimal at the end (after the one’s place) then all digits (numbers) are significant<br />

and will be counted.<br />

In the following example the zeros are significant digits and highlighted in blue.<br />

960.<br />

70050.


Rule 3: A final zero or trailing zeros in the decimal portion ONLY are<br />

significant.<br />

This rule causes the most confusion among students.<br />

In the following example the zeros are significant digits and highlighted in blue.<br />

0.07030<br />

0.00800<br />

Here are two more examples where the significant zeros are highlighted in blue.<br />

When Zeros are Not Significant Digits<br />

4.7 0 x 10−³<br />

6.5 0 0 x 10⁴<br />

Zero Type # 1 : Space holding zeros in numbers less than one.<br />

In the following example the zeros are NOT significant digits and highlighted in red.<br />

0.09060<br />

0.00400<br />

These zeros serve only as space holders. They are there to put the decimal point in its correct<br />

location.<br />

They DO NOT involve measurement decisions.<br />

Zero Type # 2 : Trailing zeros in a whole number.<br />

In the following example the zeros are NOT significant digits and highlighted in red.<br />

200<br />

25000<br />

For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point)<br />

of the numbers ONLY. Here is what to do:<br />

1) Count the number of significant figures in the decimal portion of each number in the problem. (The<br />

digits to the left of the decimal place are not used to determine the number of decimal places in the<br />

final answer.)<br />

2) Add or subtract in the normal fashion.<br />

3) Round the answer to the LEAST number of places in the decimal portion of any number in the<br />

problem<br />

The following rule applies for multiplication and division:<br />

The LEAST number of significant figures in any number of the problem determines the number of<br />

significant figures in the answer.<br />

This means you MUST know how to recognize significant figures in order to use this rule.

SCIENTIFIC NOTATION RULES<br />

How to Write Numbers in Scientific Notation<br />

Scientific notation is a standard way of writing very large and very small numbers so that they're<br />

easier to both compare and use in computations. To write in scientific notation, follow the form<br />

N X 10 ᴬ<br />

where N is a number between 1 and 10, but not 10 itself, and A is an integer (positive or negative<br />

number).<br />

RULE #1: Standard Scientific Notation is a number from 1 to 9 followed by a decimal and the<br />

remaining significant figures and an exponent of 10 to hold place value.<br />

Example:<br />

5.43 x 10 2 = 5.43 x 100 = 543<br />

8.65 x 10 – 3 = 8.65 x .001 = 0.00865<br />

****54.3 x 10 1 is not Standard Scientific Notation!!!<br />

RULE #2: When the decimal is moved to the Left the exponent gets Larger, but the value of the<br />

number stays the same. Each place the decimal moves Changes the exponent by one (1). If you<br />

move the decimal to the Right it makes the exponent smaller by one (1) for each place it is moved.<br />

Example:<br />

6000. x 10 0 = 600.0 x 10 1 = 60.00 x 10 2 = 6.000 x 10 3 = 6000<br />

(Note: 10 0 = 1)<br />

All the previous numbers are equal, but only 6.000 x 10 3 is in proper Scientific Notation.


RULE #3: To add/subtract in scientific notation, the exponents must first be the same.<br />

Example:<br />

(3.0 x 10 2 ) + (6.4 x 10 3 ); since 6.4 x 10 3 is equal to 64. x 10 2 . Now add.<br />

(3.0 x 10 2 )<br />

+ (64. x 10 2 )<br />

67.0 x 10 2 = 6.70 x 10 3 = 6.7 x 10 3<br />

67.0 x 10 2 is mathematically correct, but a number in standard scientific notation can only<br />

have one number to the left of the decimal, so the decimal is moved to the left one place and<br />

one is added to the exponent.<br />

Following the rules for significant figures, the answer becomes 6.7 x 10 3 .<br />

RULE #4: To multiply, find the product of the numbers, then add the exponents.<br />

Example:<br />

(2.4 x 10 2 ) (5.5 x 10 –4 ) = ? [2.4 x 5.5 = 13.2]; [2 + -4 = -2], so<br />

(2.4 x 10 2 ) (5.5 x 10 –4 ) = 13.2 x 10 –2 = 1.3 x 10 – 1<br />

RULE #5: To divide, find the quotient of the number and subtract the exponents.<br />

Example:<br />

(3.3 x 10 – 6 ) / (9.1 x 10 – 8 ) = ? [3.3 / 9.1 = .36]; [-6 – (-8) = 2], so<br />

(3.3 x 10 – 6 ) / (9.1 x 10 – 8 ) = .36 x 10 2 = 3.6 x 10 1

To use the Stair-Step method, find the prefix the original measurement starts with. (ex. milligram)<br />

If there is no prefix, then you are starting with a base unit.<br />

Find the step which you wish to make the conversion to. (ex. decigram)<br />

Count the number of steps you moved, and determine in which direction you moved (left or right).<br />

The decimal in your original measurement moves the same number of places as steps you moved and in the<br />

same direction. (ex. milligram to decigram is 2 steps to the left, so 40 milligrams = .40 decigrams)<br />

If the number of steps you move is larger than the number you have, you will have to add zeros to hold the<br />

places. (ex. kilometers to meters is three steps to the right, so 10 kilometers would be equal to 10,000 m)<br />

That’s all there is to it! You need to be able to count to 6, and know your left from your right!<br />

Dimensional Analysis<br />

This is a way to convert from one unit of a given substance to<br />

another unit using ratios or conversion units. What this video<br />

www.youtube.com/watch?v=aZ3J60GYo6U<br />

Let’ look at a couple of examples:<br />

1. Convert 2.6 qt to mL.<br />

First we need a ratio or conversion unit so that we can go from quarts to milliliters. 1.00 qt = 946 mL<br />

Next write down what you are starting with<br />

2.6 qt<br />

Then make you conversion tree<br />

2.6 qt<br />

Then fill in the units in your ratio so that you can cancel out the original unit and will be left with the<br />

unit you need for the answer. Cross out units, one at a time that are paired, and one on top one on<br />

the bottom.<br />

2.6 qt mL<br />

qt<br />

Now fill in the values from the ratio.<br />

2.6 qt 946 mL<br />

1.00 qt<br />

Now multiply all numbers on the top and multiply all numbers on the bottom and write them as a<br />

fraction.<br />

2.6 qt 946 mL = 2,459.6 mL<br />

1.00 qt 1.00<br />

Now divide the top number by the bottom number and write that number with the unit that was not<br />

crossed out.


1qt=32 oz 1gal = 4qts 1.00 qt = 946 mL 1L = 1000mL<br />

Atoms Are Building Blocks<br />

Atoms are the basis of chemistry. They are the basis for everything in the Universe. You<br />

should start by remembering that matter is composed of atoms. Atoms and the study of<br />

atoms are a world unto themselves. We're going to cover basics like atomic structure<br />

and bonding between atoms.<br />

Smaller Than Atoms?<br />

Are there pieces of matter that are smaller than atoms?<br />

Sure there are. You'll soon be learning that atoms are<br />

composed of pieces like electrons, protons, and neutrons.<br />

But guess what? There are even smaller particles moving<br />

around in atoms. These super-small particles can be found<br />

inside the protons and neutrons. Scientists have many<br />

names for those pieces, but you may have heard of<br />

nucleons and quarks. Nuclear chemists and physicists<br />

work together at particle accelerators to discover the<br />

presence of these tiny, tiny, tiny pieces of matter.<br />

Even though super-tiny atomic particles exist, you only<br />

need to remember the three basic parts of an atom: electrons, protons, and neutrons.<br />

What are electrons, protons, and neutrons? A picture works best to show off the idea.<br />

You have a basic atom. There are three types of pieces in that atom: electrons, protons,<br />

and neutrons. That's all you have to remember. Three things! As you know, there are<br />

almost 120 known elements in the periodic table. Chemists and physicists haven't<br />

stopped there. They are trying to make new ones in labs every day. The thing that<br />

makes each of those elements different is the number of electrons, protons, and<br />

neutrons. The protons and neutrons are always in the center of the atom. Scientists call<br />

the center region of the atom the nucleus. The nucleus in<br />

a cell is a thing. The nucleus in an atom is a place where<br />

you find protons and neutrons. The electrons are always<br />

found whizzing around the center in areas called shells or<br />

orbitals.<br />

You can also see that each piece has either a "+", "-", or a<br />

"0." That symbol refers to the charge of the particle. Have<br />

you ever heard about getting a shock from a socket, static<br />

electricity, or lightning? Those are all different types of<br />

electric charges. Those charges are also found in tiny particles of matter. The electron<br />

always has a "-", or negative, charge. The proton always has a "+", or positive, charge. If<br />

the charge of an entire atom is "0", or neutral, there are equal numbers of positive and<br />

negative pieces. Neutral means there are equal numbers of electrons and protons. The<br />

third particle is the neutron. It has a neutral charge, also known as a charge of zero. All<br />

atoms have equal numbers of protons and electrons so that they are neutral. If there are<br />

more positive protons or negative electrons in an atom, you have a special atom called<br />

an ion.


http://www.learner.org/interactives/periodic/basics_interactive.html


Looking at Ions<br />

We haven’t talked about ions before, so let’s get down to basics. The<br />

atomic number of an element, also called a proton number, tells you the<br />

number of protons or positive particles in an atom. A normal atom has a<br />

neutral charge with equal numbers of positive and negative particles.<br />

That means an atom with a neutral charge is one where the number of<br />

electrons is equal to the atomic number. Ions are atoms with extra<br />

electrons or missing electrons. When you are missing an electron or<br />

two, you have a positive charge. When you have an extra electron<br />

or two, you have a negative charge.<br />

What do you do if you are a sodium (Na) atom? You have eleven<br />

electrons — one too many to have an entire shell filled. You need to<br />

find another element that will take that electron away from you. When you lose that<br />

electron, you will you’ll have full shells. Whenever an atom has full shells, we say it is<br />

"happy." Let's look at chlorine (Cl). Chlorine has seventeen electrons and only needs<br />

one more to fill its third shell and be "happy." Chlorine will take your extra sodium<br />

electron and leave you with 10 electrons inside of two filled shells. You are now a happy<br />

atom too. You are also an ion and missing one electron. That missing electron gives you<br />

a positive charge. You are still the element sodium, but you are now a sodium ion (Na + ).<br />

You have one less electron than your atomic number.<br />

Ion Characteristics<br />

So now you've become a sodium ion. You have ten electrons.<br />

That's the same number of electrons as neon (Ne). But you<br />

aren't neon. Since you're missing an electron, you aren't really<br />

a complete sodium atom either. As an ion you are now<br />

something completely new. Your whole goal as an atom was<br />

to become a "happy atom" with completely filled electron<br />

shells. Now you have those filled shells. You have a lower<br />

energy. You lost an electron and you are "happy." So what<br />

makes you interesting to other atoms? Now that you have<br />

given up the electron, you are quite electrically attractive.<br />

Other electrically charged atoms (ions) of the opposite charge<br />

(negative) are now looking at you and seeing a good partner to<br />

bond with. That's where the chlorine comes in. It's not only chlorine. Almost any ion with<br />

a negative charge will be interested in bonding with you.


Electrovalence<br />

Don't get worried about the big word. Electrovalence is just another word for something<br />

that has given up or taken electrons and become an ion. If you look at the periodic table,<br />

you might notice that elements on the left side usually become positively charged ions<br />

(cations) and elements on the right side get a negative charge (anions). That trend<br />

means that the left side has a positive valence and the right side has a negative<br />

valence. Valence is a measure of how much an atom wants to bond with other atoms. It<br />

is also a measure of how many electrons are excited about bonding with other atoms.<br />

There are two main types of bonding, covalent and electrovalent. You may have heard<br />

of the term "ionic bonds." Ionic bonds are electrovalent bonds. They are just groups of<br />

charged ions held together by electric forces. When in the presence of other ions, the<br />

electrovalent bonds are weaker because of outside electrical forces and attractions.<br />

Sodium and chlorine ions alone have a very strong bond, but as soon as you put those<br />

ions in a solution with H + (Hydrogen ion), OH - (Hydroxide), F - (Fluorine ion) or Mg ++<br />

(Magnesium ion), there are charged distractions that break the Na-Cl bond.<br />

Look at sodium chloride (NaCl) one more time. Salt is a very strong bond when it is<br />

sitting on your table. It would be nearly impossible to break those ionic/electrovalent<br />

bonds. However, if you put that salt into some water (H 2 O), the bonds break very<br />

quickly. It happens easily because of the electrical attraction of the water. Now you have<br />

sodium (Na + ) and chlorine (Cl - ) ions floating around the solution. You should remember<br />

that ionic bonds are normally strong, but they are very weak in water.


Neutron Madness<br />

We have already learned that ions are atoms that are<br />

either missing or have extra electrons. Let's say an atom<br />

is missing a neutron or has an extra neutron. That type of<br />

atom is called an isotope. An atom is still the same<br />

element if it is missing an electron. The same goes for<br />

isotopes. They are still the same element. They are just a<br />

little different from every other atom of the same element.<br />

For example, there are a lot of carbon (C) atoms in the<br />

Universe. The normal ones are carbon-12. Those atoms have 6 neutrons. There are a<br />

few straggler atoms that don't have 6. Those odd ones may have 7 or even 8 neutrons.<br />

As you learn more about chemistry, you will probably hear about carbon-14. Carbon-14<br />

actually has 8 neutrons (2 extra). C-14 is considered an isotope of the element carbon.<br />

Messing with the Mass<br />

If you have looked at a periodic table, you may have noticed that the atomic mass of<br />

an element is rarely an even number. That happens because of the isotopes. If you are<br />

an atom with an extra electron, it's no big deal. Electrons don't have much of a mass<br />

when compared to a neutron or proton.<br />

Atomic masses are calculated by figuring out the<br />

amounts of each type of atom and isotope there are in<br />

the Universe. For carbon, there are a lot of C-12, a<br />

couple of C-13, and a few C-14 atoms. When you<br />

average out all of the masses, you get a number that is a<br />

little bit higher than 12 (the weight of a C-12 atom). The<br />

average atomic mass for the element is actually 12.011.<br />

Since you never really know which carbon atom you are<br />

using in calculations, you should use the average mass<br />

of an atom.<br />

Bromine (Br), at atomic number 35, has a greater variety of isotopes. The atomic mass<br />

of bromine (Br) is 79.90. There are two main isotopes at 79 and 81, which average out<br />

to the 79.90amu value. The 79 has 44 neutrons and the 81 has 46 neutrons. While it<br />

won't change the average atomic mass, scientists have made bromine isotopes with<br />

masses from 68 to 97. It's all about the number of neutrons. As you move to higher<br />

atomic numbers in the periodic table, you will probably find even more isotopes for<br />

each element.

electron configurations.<br />

1. Aufbau<br />

Notation<br />

nO e<br />

where<br />

n is the energy level<br />

O is the orbital type (s, p, d, or f)<br />

e is the number of electrons in that orbital shell<br />

Principle<br />

electrons will first occupy orbitals of the lowest energy level<br />

2. Hund rule<br />

when electrons occupy orbitals of equal energy, one electron enters each orbital until<br />

all the orbitals contain one electron with the same spin.<br />

3. Pauli exclusion principle<br />

an orbital contains a maximum of 2 electrons and<br />

paired electrons will have opposite spin

Atomic size<br />

Increases<br />

increases<br />

As you go from the top to the boom your increasing energy level which increases<br />

size.<br />

when you go from le to right you increase mass, mass has a gravitaonal pull<br />

that’s greater which pulls the electrons in closer which makes it smaller.


Ionizaon Energy<br />

increase<br />

increase<br />

Ionizaon energy is energy needed to take away an electron away from an atom.<br />

The closer to the center the harder to take electrons from nuclei .<br />

The heavier the mass the more pull it has the harder to take .


Electron negavity<br />

increase<br />

increase<br />

Is the ability for an atom to take the electron.<br />

From le to right it increases because they are heaver<br />

And from boom to top increases because it is so close and the nuclei<br />

has a stronger pull.


Ion size<br />

The actual size<br />

The boom will be bigger because the top will have less protons then<br />

the booms which make them slower<br />

The caons are decreasing in size because they are giving up electrons<br />

and going down an energy level<br />

And the anion receive ions and get bigger so the pull is stronger .

Chapter 25.1<br />

Radioactivity: the spontaneous emission of rays or particles from certain elements.<br />

Nuclear radiation: The rays and particles emitted from a radioactive source.<br />

Three types of radiation: alpha radiation, beta radiation, gamma radiation.<br />

Alpha: helium nuclei<br />

Beta: electrons<br />

Gamma: high-energy electromagnetic radiation.<br />

An electric field has a different effect on each type of radiation.<br />

Alpha and beta move in opposite directions. Alpha moves towards negative plate, and beta<br />

moves toward positive plate.<br />

Gamma rays have no mass and no electric charge.<br />

When an atom loses an alpha particle, the atomic number of the product is lowered by 2 and its<br />

mass is lowered by 4.<br />

Radioactive decay is spontaneous process that does not require an input of energy.<br />

If a product is unstable it will decay also.<br />

Because of their large mass and charge, alpha particles are the least penetrating of the three main<br />

types.<br />

Radiation is emitted during radioactive decay.


25.2<br />

Nuclear force: Is an attractive force that acts between all nuclear particles that are extremely<br />

close together, such as protons and neutrons in a nucleus.<br />

Band off stability: for elements of low atomic number below about 20, this ratio is about 1.<br />

Above atomic number 20, stable nuclei have more neutrons than protons.<br />

Positron: is a particle with the mass of an electron but a positive charge.<br />

Half life: is the time required for one-half of the nuclei in a radioisotope sample to decay to<br />

products.<br />

All atomic nuclei, except those hydrogen atoms, consist of neutrons and two or more protons.<br />

A nucleus may be unstable and undergo spontaneous decay for different reasons.<br />

A neutron that emits an electron becomes a proton.<br />

Other nuclei are unstable because they have too few neutrons relative to the number of protons.<br />

These nuclei increase their stability by converting a proton to a neutron.<br />

Transmutation: The conversion of an atom of one element into an atom of another element.<br />

These are common in nature.<br />

Rutherford’s experiment eventually led to the discovery of the proton. He and other scientist<br />

noticed a pattern as they did different transmutations experiments.<br />

Elements with the atomic number above 92 are transuranium elements. All of these elements are<br />

radioactive, and undergo transmutation.<br />

James Chadwick discovered the neutron in 1932, neutrons were produced when beryllium-9 was<br />

bombarded with alpha particles.


Metallic bonding<br />

The students will learn how ionic compounds form<br />

and how metallic bounding affects the properties of<br />

Is the electromagnetic interaction between delocalized electrons, called conduction<br />

electrons, gathered in an electron sea, and the metallic nuclei within metals.<br />

Although the term metallic bond is often used in contrast to the term covalent<br />

bond, it is preferable to use the term metallic bonding, because this type of bonding<br />

is collective in nature and a single metallic bond does not exist.<br />

A common characteristic of metallic elements is they contain only one to three<br />

electrons in the outer shell.<br />

CaF4<br />

1- Same no prefix<br />

2- Di<br />

3- Tri<br />

4- Tetra<br />

K^+O^2- potassium oxide<br />

K2O


Metallic Bonds:<br />

In the metallic bond, an atom achieves a more stable<br />

configuration by sharing the electrons in its outer shell with<br />

many other atoms. Metallic bonds are most common in elements<br />

where the valence electrons are not very tightly bound with the<br />

nucleus, mostly metals, hence the name metallic bonding. In this<br />

type of bond, each atom in a metal crystal contributes all the<br />

electrons in its valence shell to all other atoms in the crystal.<br />

Metals tend to have high melting points and boiling points<br />

suggesting strong bonds between the atoms. Even a metal like<br />

sodium (melting point 97.8°C) melts at a considerably higher<br />

temperature than the element (neon) which precedes it in the<br />

Periodic Table.<br />

Transition metals tend to have particularly high melting points<br />

and boiling points. The reason is that they can involve the 3d<br />

electrons in the delocalisation as well as the 4s. The more<br />

electrons you can involve, the stronger the attractions tend to be.


A method and apparatus for manufacturing composite materials are provided. In a first<br />

embodiment, a binding material is placed on a heat-resistant filter that is placed on hollow<br />

particles in a pressurizable container. Under pressure and heat, the binding material flows<br />

through the filter and infiltrates the spaces between the hollow particles. In a further<br />

embodiment, composite material wire is produced by coating the surfaces of inorganic fiber<br />

bundles with a metal oxide by dipping in a solution of a hydrolyzable organic metal compound<br />

and hydrolyzing and heat-treating prior to continuous infiltration under pressure.


Ionic compounds.<br />

In chemistry, an ionic compound is a chemical compound in<br />

which ions are held together in a lattice structure by ionic bonds.<br />

Usually, the positively charged portion consists of metal cations<br />

and the negatively charged portion is an anion or polyatomic<br />

ion. Ions in ionic compounds are held together by the<br />

electrostatic forces between oppositely charged bodies. Ionic<br />

compounds have high melting and boiling points, and they are<br />

hard and very brittle.<br />

Ions can be single atoms, as the sodium and chlorine in common<br />

table salt sodium chloride, or more complex groups such as the<br />

carbonate in calcium carbonate. But to be considered an ion,<br />

they must carry a positive or negative charge. Thus, in an ionic<br />

bond, one 'bonder' must have a positive charge and the other a<br />

negative one. By sticking to each other, they resolve, or partially<br />

resolve, their separate charge imbalances. Positive to positive<br />

and negative to negative ionic bonds do not occur. (For an easily<br />

visible analogy, experiment with a pair of bar magnets.)<br />

Chemical compounds are never strictly ionic. Even the most<br />

electronegative/electropositive pairs such as caesium fluoride<br />

exhibit a degree of covalency. Similarly, covalent compounds<br />

often exhibit charge separations. See also HSAB theory.

How to Balance Chemical Equations<br />

A chemical equation is a theoretical or written representation of what happens during a chemical<br />

reaction. The law of conservation of mass states that no atoms can be created or destroyed in a<br />

chemical reaction, so the number of atoms that are present in the reactants has to balance the<br />

number of atoms that are present in the products. Follow this guide to learn how to balance chemical<br />

equations.<br />

Step 1<br />

Write down your given equation. For this example, we will use:<br />

C 3 H 8 + O 2 --> H 2 O + CO 2<br />

Step 2<br />

Write down the number of atoms that you have on each side of the equation. Look at the subscripts<br />

next to each atom to find the number of atoms in the equation.<br />

Left side: 3 carbon, 8 hydrogen and 2 oxygen<br />

Right side: 1 carbon, 2 hydrogen and 3 oxygen


Step 3<br />

Always leave hydrogen and oxygen for last. This means that you will need to balance the carbon<br />

atoms first.<br />

Step 4<br />

Add a coefficient to the single carbon atom on the right of the equation to balance it with the 3 carbon<br />

atoms on the left of the equation.<br />

C 3 H 8 + O 2 --> H 2 O + 3CO 2<br />

The coefficient 3 in front of carbon on the right side indicates 3 carbon atoms just as the subscript 3<br />

on the left side indicates 3 carbon atoms.<br />

In a chemical equation, you can change coefficients, but you should never alter the subscripts.


Step 5<br />

Balance the hydrogen atoms next. You have 8 on the left side, so you'll need 8 on the right side.<br />

C 3 H 8 + O 2 --> 4H 2 O + 3CO 2<br />

On the right side, we added a 4 as the coefficient because the subscript showed that we already<br />

had 2 hydrogen atoms.<br />

When you multiply the coefficient 4 times the subscript 2, you end up with 8.<br />

Step 6<br />

Finish by balancing the oxygen atoms.<br />

Because we've added coefficients to the molecules on the right side of the equation, the number of<br />

oxygen atoms has changed. We now have 4 oxygen atoms in the water molecule and 6 oxygen<br />

atoms in the carbon dioxide molecule. That makes a total of 10 oxygen atoms.<br />

Add a coefficient of 5 to the oxygen molecule on the left side of the equation. You now have 10<br />

oxygen molecules on each side.<br />

C 3 H 8 + 5O 2 --> 4H 2 O + 3CO 2.<br />

The carbon, hydrogen and oxygen atoms are balanced. Your equation is complete.

Additional Notes:


Categories of Reactions<br />

All chemical reactions can be placed into one of six categories. Here they are, in no<br />

particular order:<br />

1) Synthesis: A synthesis reaction is when two or more simple compounds combine to form a<br />

more complicated one. These reactions come in the general form of:<br />

A + B ---> AB<br />

One example of a synthesis reaction is the combination of iron and sulfur to form iron (II) sulfide:<br />

8 Fe + S 8 ---> 8 FeS<br />

If two elements or very simple molecules combine with each other, it’s probably a synthesis reaction.<br />

The products will probably be predictable using the octet rule to find charges.<br />

2) Decomposition: A decomposition reaction is the opposite of a synthesis reaction - a<br />

complex molecule breaks down to make simpler ones. These reactions come in the general form:<br />

AB ---> A + B<br />

One example of a decomposition reaction is the electrolysis of water to make oxygen and hydrogen<br />

gas:<br />

2 H 2O ---> 2 H 2 + O 2<br />

If one compound has an arrow coming off of it, it’s probably a decomposition reaction. The products<br />

will either be a couple of very simple molecules, or some elements, or both.<br />

3) Single displacement: This is when one element trades places with another element in a<br />

compound. These reactions come in the general form of:<br />

A + BC ---> AC + B<br />

One example of a single displacement reaction is when magnesium replaces hydrogen in water to<br />

make magnesium hydroxide and hydrogen gas:<br />

Mg + 2 H 2O ---> Mg(OH) 2 + H 2<br />

If a pure element reacts with another compound (usually, but not always, ionic), it’s probably a single<br />

displacement reaction. The products will be the compounds formed when the pure element switches<br />

places with another element in the other compound.<br />

Important note: these reactions will only occur if the pure element on the reactant side of the equation<br />

is higher on the activity series than the element it replaces.


4) Double displacement: This is when the anions and cations of two different molecules<br />

switch places, forming two entirely different compounds. These reactions are in the general form:<br />

AB + CD ---> AD + CB<br />

One example of a double displacement reaction is the reaction of lead (II) nitrate with potassium<br />

iodide to form lead (II) iodide and potassium nitrate:<br />

Pb(NO 3) 2 + 2 KI ---> PbI 2 + 2 KNO 3<br />

If two ionic compounds combine, it’s probably a double displacement reaction. Switch the cations<br />

and balance out the charges to figure out what will be made.<br />

Important note: These reactions will only occur if both reactants are soluble in water and only one<br />

product is soluble in water.<br />

5) Acid-base: This is a special kind of double displacement reaction that takes place when an<br />

acid and base react with each other. The H + ion in the acid reacts with the OH - ion in the base,<br />

causing the formation of water. Generally, the product of this reaction is some ionic salt and water:<br />

HA + BOH ---> H 2O + BA<br />

One example of an acid-base reaction is the reaction of hydrobromic acid (HBr) with sodium<br />

hydroxide:<br />

HBr + NaOH ---> NaBr + H 2O<br />

If an acid and a base combine, it’s an acid-base reaction. The products will be an ionic compound<br />

and water.<br />

6) Combustion: A combustion reaction is when oxygen combines with another compound to<br />

form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An<br />

example of this kind of reaction is the burning of napthalene:<br />

C 10H 8 + 12 O 2 ---> 10 CO 2 + 4 H 2O<br />

If something that has carbon and hydrogen reacts with oxygen, it’s probably a combustion reaction.<br />

The products will be CO 2 and H 2 O.<br />

Follow this series of questions. When you can answer "yes" to a question, then<br />

stop!<br />

1) Does your reaction have two (or more) chemicals combining to form one chemical? If yes, then it's<br />

a synthesis reaction<br />

2) Does your reaction have one large molecule falling apart to make several small ones? If yes, then<br />

it's a decomposition reaction<br />

3) Does your reaction have any molecules that contain only one element? If yes, then it's a single<br />

displacement reaction<br />

4) Does your reaction have water as one of the products? If yes, then it's an acid-base reaction<br />

5) Does your reaction have oxygen as one of it's reactants and carbon dioxide and water as<br />

products? If yes, then it's a combustion reaction<br />

6) If you haven't answered "yes" to any of the questions above, then you've got a double<br />

displacement reaction.

Predicting Reaction Products – Answers<br />

Predict the products of each of the following chemical reactions. If a reaction will not occur, explain why not:<br />

1) ____ Ag 2 SO 4 + ____ NaNO 3 → no reaction!<br />

Examining this reaction, it appears that a double displacement reaction will occur. This would lead to the conclusion that<br />

the products would be AgNO3 and Na2SO4. However, for this reaction to occur, both reactants and only one of the<br />

products must be soluble in water. If you look up the solubilities on a chart, you’ll find that Ag2SO3 is partly soluble in<br />

water, and all of the other compounds are totally soluble in water. This tells us that this reaction will not occur.<br />

2) ____ NaI + ____ CaSO 4 → no reaction!<br />

Another double displacement reaction, this time with Na2SO4 and CaI2 as products. Because both products are soluble<br />

in water and CaSO4 is only partially soluble in water, the conditions for a successful double displacement reaction are not<br />

met.<br />

3) 2 HNO 3 + 1 Ca(OH) 2 → 1 Ca(NO 3 ) 2 + 2 H 2 O<br />

It’s an acid-base reaction, and acid-base reactions occur readily whether or not the reactants are both soluble in water.<br />

4) 1 CaCO 3 → 1 CaO + 1 CO 2<br />

It’s a decomposition reaction. If you didn’t guess that these were the products, you should have at least known that it was<br />

a decomposition reaction and predicted that this would have broken into its constituent elements, Ca, C, and O2.<br />

5) 1 AlCl 3 (aq) + 1 (NH 4 ) 3 PO4(aq) → AlPO 4 (s) + 3 NH 4 Cl(aq)<br />

This is a double displacement reaction, except in this case both of the reactants and only one product are soluble in<br />

water. Because the conditions for a successful reaction are met, the reaction does occur!<br />

6) ____ Pb + ____ Fe(NO 3 ) 3 →<br />

Though this is a single displacement reaction, lead is lower on the activity series than the iron it would replace. As a<br />

result, this reaction does not occur.<br />

7) 2 C 3 H 6 + 9 O 2 → 6 CO 2 + 6 H 2 O<br />

The reactants suggest that this is a combustion reaction, meaning that the products must be carbon dioxide and water.<br />

Once you figure this out, the only thing left to do is balance it, as shown.<br />

8) 2 Na + 1 CaSO 4 → 1 Na 2 SO 4 + 1 Ca<br />

This should clearly be a single displacement reaction. Because sodium is higher on the activity series than calcium, this<br />

reaction does occur.


Gas laws<br />

Cody N, Marc M, Eddie V, <strong>Louis</strong> P


Boyle’s Law<br />

States that for a given mass of gas at room<br />

temperature, the volume of the gas varies with<br />

pressure.


Formula and Usage<br />

P 1<br />

x V 1<br />

= P 2<br />

x V 2<br />

Question 9# - N 2<br />

O is used as an anesthetic. The pressure on 2.50L of N 2<br />

O<br />

changes from 105 kPa to 40.5 kPa. If the temperature does not change, what<br />

will the new volume be?<br />

Known<br />

105kPa x 2.50L=262.5L<br />

40.5kPa = 6.48L<br />

P 1<br />

105kPa<br />

V 1<br />

2.50L<br />

P 2<br />

40.5kPa

Charles’s Law<br />

States that volume of a fixed mass of gas is<br />

directly proportional to its Kelvin temperature if<br />

the pressure is kept constant.


Formula and Usage<br />

V 1<br />

/ T 1<br />

= V 2<br />

/ T 2<br />

(K = o C + 273)<br />

If a sample of gas occupies 6.80 L at 325 o C,<br />

what will its volume be at 25 o C if the pressure<br />

does not change?<br />

K = 325 o C + 273=598 V 2<br />

= V 1<br />

x T 2<br />

/ T 1<br />

K = 25 o C + 273=298 V 2<br />

= 6.80L x 598K/ 298K<br />

V 2<br />

= 13.6 L

Gay-Lussac’s Law<br />

States that if a gas is contained in a constant<br />

volume then the pressure of the gas is directly<br />

proportional to the Kelvin temperature.


Formula and Usage<br />

Formula: P1/T1=P2/T2<br />

If the pressure of a gas is at 103 kPa at 25 C.<br />

What is the pressure of the gas at 928 C.<br />

P1= 103 kPa K=C+273 P2= T2 x P1<br />

P2= ? --> 415 kPa T1<br />

T1= 25 C P2= 1,201 K x 103 kPa<br />

T2= 928 C 298 K

Heat of Fusion of Water<br />

334 J/g = 80 cal/g<br />

Specific Heat of Water<br />

4.18 J/g ∙ᵒC<br />

Heat of fusion is the amount of heat energy required to change the state of a substance from solid to<br />

liquid. This example problem demonstrates how to calculate the amount of energy required to melt a<br />

sample of water ice.<br />

With Graham's Law, you can find the effusion rates for two gases or the molecular mass of a gas.<br />

This ratio of effusion rates follows the pattern that the gas with the lesser molecular mass has a<br />

greater rate of effusion.<br />

Learning Goals<br />

The students will learn what are the factors that determine and characteristics that distinguish gases<br />

liquids and solids and how substances change from one state to another.<br />

The students will learn how gases respond to changes in pressure, volume, and temperature and why<br />

the ideal gas law is useful even though ideal gases do not exist.<br />

The students will learn how the interactions between water molecules account for the unique<br />

properties of water and how aqueous solutions form.<br />

The student will learn how energy is converted in a chemical or physical process and how to<br />

determine the amount of energy is absorbed or released in that process.
