Down
- 1. A solution that has a pH above 7.0 (neutral).
- 2. Characteristics that can be determined without a chemical reaction and that do not cause a chemical change in the substance.
- 4. A change in the chemical composition or make-up of a substance.
- 5. A chemical combination of two or more atoms in definite (fixed) proportions.
- 6. Also known as compounds; a chemical combination of two or more atoms of different elements in definite (fixed) proportions.
- 8. Colorless gas with a pungent odor that is composed of hydrogen and nitrogen.
- 12. A chemical reaction that combines a substance with oxygen to produce an oxide.
- 14. Also known as redox; a chemical reaction in which the oxidizing agent is reduced (by losing oxygen) and the reducing agent is oxidized (by gaining oxygen).
- 15. A substance that adds hydrogen to a chemical compound or subtracts oxygen from the compound.
- 16. A colorless liquid or white crystals with a strong unpleasant odor that is used in permanent waving solutions.
