Use the space provided to write out the steps you take to solve different types of problems. Use any additional space for notes. These 2 pages should be full when you turn in your notebook. Steps to solve problems Mole to Mole: In order to balance an equation you need to know the amount of the element on both sides. for example: 4_KNO3 ----> 4_KNO2 +2_O2 K1 4 N1 4 O3 12 K1 4 N1 4 O4 12 Since both sides at first weren't equal you had to find a balance for both sides, but oxygen wasn't equal so you had to multiply each side by 4 to be able to equalize the moles. You also had to alter the amount of K and Nitrogen to be able to change Oxygen on the left side of the equation. Mole to mole: in order to be able to change the mole of something you have to know the given mole first to convert it to the moles you actually have in the problem, then take that and convert it to the different elements amount of moles In this problems it thier is 6 moles of KNO3 it goes to 4 moles then 1 to 4 moles of KNO2 then to 2 moles of O2 106
You need the problem to be balanced in order for yuo to be albe to even sovle so you have to get the grams or mass of the element so you can figure out the total mount of a substance you got or moles depending on the type of reaction and problem. Solving a problem where it is in a word problem you have to identify the element or know the reactant already. Once you figure out the compound then you have to find out the charges by what group it is in. group one elements have a charge of positive one while elements in group 17 have a negative one charge. Note: flourine is the least electronega element. 107
