9. A chemical that is created as a chemical reaction occurs
11. A chemical that is at the start of the reaction, but is used up as the reaction proceeds
12. List of elements that ranks elements based on reactivity

1. Type of equation that show all of the elements or molecules that are involved in a reaction.
3. A number placed in front of a molecule or element to balance the equation
5. A reaction where one complex compound breaks down into two or more elements or simpler compounds
