3. Description of a solution in which the hydronium ion concentration is equal to the hydroxide ion concentration.
4. The reacting substances in a chemical reaction.
6. A rapid exothermic oxidation reduction reaction between a material and a molecular oxygen.
10. Description of a substance that can behave as either an acid or a base.
13. A measure of the acidity of a solution; equal to the negative logarithm of the hydronium ion concentration.
16. equation A representation of a chemical reaction in which reactants are written to the left of an arrow that points toward the products on the right
17. Description of a chemical reaction in which there is a net absorption of energy.
19. energy The minimum energy required in order for a chemical reaction to proceed.
21. Any substance that increases the rate of a chemical reaction without itself being consumed by the reaction.

1. The deterioration of a metal, typically caused by atmospheric oxygen.
2. ion A polyatomic ion made by adding a proton to a water molecule.
5. A reaction between an acid and a base.
7. ion A polyatomic ion made by removing a proton from a water molecule.
8. The process by which a reactant gains one or more electrons.
9. Description of a chemical reaction in which there is a net release of energy.
11. A substance that accepts hydrogen ions.
12. energy The amount of energy required to pull two bonded atoms apart
14. description of a solution in which the hydroxide ion concentration is higher than the hydronium ion.
15. The new materials formed in a chemical reaction.
18. The process by which a reactant loses one or more electrons.
