Across
- 2. One half of an oxidation–reduction reaction, represented by an equation showing electrons as either reactants or products.
- 7. A reaction between an acid and a base.
- 8. The deterioration of a metal, typically caused by atmospheric oxygen.
- 9. Description of a chemical reaction in which there is a net absorption of energy.
- 10. A substance that lowers the activation energy of a chemical reaction, which allows for the reaction to proceed at a faster rate.
Down
- 1. Description of a substance that can behave as either an acid or a base.
- 3. The minimum energy required in order for a chemical reaction to proceed.
- 4. The process by which a reactant loses one or more electrons.
- 5. A polyatomic ion made by adding a proton (hydrogen ion) to a water molecule.
- 6. The amount of energy required to pull two bonded atoms apart, which is the same as the amount of energy released when the two atoms are brought together into a bond.
