Formula & Equations
Study Jams Summary-
Elements are at the simplest state and can't be broken down any more. When elements have a reaction, they make a compound. Chemical formulas represent atoms when they change. Subscripts tell you how many of each element are in a compound.

Part l
1. A combination of symbols that show how many elements are in a compound
2. The elements that are in a compound and the number of atoms of each element in the compound
3. The charges and oxidation numbers
Part ll
1. Nitrogen, hydrogen, oxygen, and chromium
2. 8
3. 2
4. If the elements are the same number on both sides, it's balanced. If it's uneven then it's unbalanced.
5. Unbalanced
6. There are 3 less oxygen atoms on the right and 6 less hydrogen elements on the right
Part lll
1. A chemical reaction
2. The reactant, the reaction, and the product
4. The law of Conservation of Mass says that all reactions have to have a balanced reactant and product. So if a chemical equation is not balanced, you know it's not right.
5. They add or take away the number of molecules in an equation
