Welcome to Chem 25 - your introduction to chemistry as the language of matter. This course is intended for
students who wish to meet general education requirements in physical science or need background
preparation for CHEM 1A. The course includes basic chemical laboratory techniques and methods, a survey of
important chemical principles with emphasis on problem solving, and an introduction to the elements and their
compounds. Prerequisite: Passing score on math placement test or MA105/108.
CHEM 25 LEARNING OBJECTIVES:
You may not believe it, but by the end of this quarter, you will be able to:
Understand the scientific method and distinguish between a theory and a scientific law.
Report the correct number of significant figures in measured and calculated quantities.
Use dimensional analysis to set up and solve numerical problems.
Classify matter and describe the properties of matter.
Understand and apply the assumptions of Dalton's atomic theory to describe the structure of the atom.
Use the periodic table to explain and predict the properties of elements.
Interpret chemical formulas and write the names and formulas for ionic compounds, molecular
compounds, and acids.
Understand the meaning and uses of the mole and of Avogadro's number.
Write, balance, and classify chemical equations and recognize patterns of chemical reactivity to
predict the products of a chemical reaction.
Perform stoichiometry calculations and understand the concept of a limiting reactant.
Understand the basis of the gas laws and derive the gas laws from the ideal gas law.
Describe the properties of solids and liquids and understand the manifestations of intermolecular forces.
Describe the properties of solutions and define and use molarity in calculations.
Describe the properties of acids and bases and understand the basis of the pH scale.
REQUIRED COURSE MATERIALS:
Text: Introductory Chemistry, N. Tro, 4th Edition (Foothill or regular version or etext)

CLASS POLICIES: These policies make up part of the basis for your subjective grade
Attendance and preparation: both are expected and will be assessed as part of your subjective grade
o Plan to arrive to class and lab on time, with the proper supplies, including a calculator
o Being prepared for lab (understanding the lab procedure) is essential for safety
o If you must be absent, then it is in your best interest to contact the instructor as you may be
dropped from the course after two unexcused absences. If you miss the first two lectures or the
first lab session, you will automatically be dropped for non-attendance.
Laptops in class: Since we are in a large lecture hall and what is on your screen is very distracting to
those around you, laptops are not allowed to be used during lectures (or lab lectures). If you have a
special need, contact the instructor.
Paying attention in class: Use of a cell phone in lectures or lab for any reason is not allowed unless you
have special permission from the instructor. If you have an emergency call, quietly leave the class.

-----------------------------------------------------------------------------------------------------------------------------------------------
Instructor: Dr. Mossman Email: mossmancraig@foothill.edu
Office Hours Room 4414: Tues and Thurs 10:00 -11:45 pm,
LABORATORY LECTURE: The beginning of each laboratory session is designated as a laboratory lecture period
for which you must be on time in order to perform the scheduled experiment. In addition to arriving to class on
time, you are also required to:
Read and understand both the background information and the procedure BEFORE coming to the
laboratory
Complete the online prelab assignment prior to class time
Bring your hand-written outline of the experimental procedure to class.
The instructor will use this lecture period to outline important details of the procedure, overview theory and
calculations, and emphasize safety hazards and proper chemical disposal. If you repeatedly fail to comply with
the procedures for proper chemical disposal, then you will be dropped from this course.
LABORATORY EXPERIMENTS:
The laboratory schedule for this course is on the overall course schedule.
Scheduled experiments are conducted in Lab 4812 following the laboratory lecture time.
LABORATORY CHECK-IN:
For this course, you must provide a $20.00 deposit for having a laboratory drawer. If you do not have your
deposit on file with the stockroom by the end of the 2nd week of the course, then you will lose access to your
drawer and thus be unable to perform any experiments. If you drop this course, then you must arrange to
check-out with the instructor to get your deposit back before the final.
LABORATORY SAFETY AND PREPARATION:
Laboratory safety will be discussed in the mandatory first lab session. It is expected that you put safety first in
the laboratory, and if you deliberately neglect the directed safety rules, then you will be dropped from this
course. Any student who is absent and does not make arrangements to attend another lab session the first
week will be dropped from the class.
A safety exam will be given the second lab session, which must be passed with a grade of 85% or higher to
remain in the class.
For your protection, safety goggles or visorgogs with indirect ventilation and an ANSI minimum rating of Z87
must be worn AT ALL TIMES in the laboratory. Appropriate clothing and shoes are also required.
LABORATORY GRADE COMPONENTS:
Your lab grade is composed of scores from the online prelab assignments, procedure outlines, laboratory
assignments and lab quizzes.
PRELABS: The prelab assignments are completed online using Mastering Chemistry and are be due
BEFORE laboratory lecture. Procedure outlines will be checked at the beginning of lab lecture.
LABORATORY ASSIGNMENTS: The nature and due date of each laboratory assignment will be specified
during the lab lecture. In general, the experiment and discussion questions will be evaluated for proper
conduct, appropriate data and correct calculations prior to the end of the lab session by the lab
instructor and a score will recorded. For many experiments, you will be collecting data with a partner,
however you must do your own calculations and formulate your own conclusions for each experiment.
There will be NO MAKE-UP EXPERIMENTS; however one laboratory assignment score will be dropped.
LAB QUIZZES: There will be two laboratory quizzes that will focus on the laboratory assignments. If you
miss a laboratory quiz, then you will receive a zero. There will be no make-up quizzes.
SUBJECTIVE EVALUATION COMPONENTS: The subjective evaluation assessed by the instructor is also
used to reward your preparedness for lecture and laboratory sessions, your ability to follow both written
and verbal instructions, your adherence to the safety rules, your cleanliness practices, and your overall
respect for the laboratory through the proper care and use of all equipment.
You must pass the lab portion of the class (>68% ) in order to receive an overall passing grade.
