1. Law of Conservation of Mass AKA: Law of Conservation of Matter

2. Mass is neither created nor destroyed during a chemical reaction

3. +
In a chemical reaction, atoms are rearranged to make new products with new properties.

4. A chemical reaction is when chemical bonds break and new bonds form.

5. Mass of Reactants = Mass of Products
Reactants Products
Mass of Reactants = Mass of Products

6. This is a balanced equation

7. Chemical reactions are represented on paper by
chemical equations.

8. Chemical equations are a shorter, easier way to show chemical reactions because they use symbols instead of words.

10. Coefficients show the number of each type of molecule in a reaction.
Subscripts show the number of each type of atom in a reaction.
