Dunn-Chapter13

2. The amount of energy required to pull two boned atoms apart, which is the same as the amount of energy released when the two atoms are brought together into a bond.
5. Description of a chemical reaction in which there is a net absorption of energy.
10. A substance that accepts hydrogen ions.
11. The minimum energy required in order for a chemical reaction to proceed.
13. A substance that donates hydrogen ions.
14. A rapid exothermic oxidation-reduction reaction between a material and molecular oxygen.
15. Description of a solution in which the hydronium ion concentration is higher than the hydroxide ion concentration.

1. Description of a substance that can behave as either an acid or a base.
3. A representation of a chemical reaction in which reactant are written to the left of an arrow that points toward the products on the right.
4. One half of an oxidation-reduction reaction, represented by an equation showing electrons as either reactants or products.
6. A polyatomic ion made by adding a proton (hydrogen on) to a water molecule.
7. Description of a chemical reaction in which there is a net release of energy.
8. A polyatomic ion made by removing a proton (hydrogen ion) from a water molecule.
9. Any substance that increases the rate of a chemical reaction without itself being consumed by the reaction.
12. Description of a solution in which the hydroxide ion concentration is higher than the hydroium ion concentration; also sometimes called 'alkaline'.
