  2. The result of a chemical reaction is called a

  3. Product

  4. To balance a chemical reaction, you must ADD or CHANGE this “big” number.

  5. Coefficient

  6. When an arrow () is used in a reaction, on which side are the reactants found?

  7. Left

  8. The “small” numbers that describe the amount of one element is called a

  9. Subscript

  10. True or false: An oxidation number is written in a chemical formula.

  11. False
