Across
- 6. reaction with their environment
- 8. in a chemical reaction, the total mass of the reactants is the same as the total
- 10. a scale that represents the acidity or basicity of a solution; pH < 7 indicates an acid; pH > 7 indicates a base; pH 7 indicates a neutral solution
- 12. indicator a solution that is used to determine the pH(amount of acid or base) of a solution
- 13. reaction a chemical reaction that absorbs energy in the form of heat
- 14. neither an acid nor a base; for example,water
Down
- 1. the gradual destruction of materials by a chemical reaction with their environment
- 2. reaction a chemical reaction that releases energy in the form of heat or light
- 3. the original substances present in a chemical reaction
- 4. a reaction between an acid and a base. A salt and water (a neutral liquid) are the products of this type of reaction
- 5. chemicals that react with a base to produce a salt and water; edible acids taste sour
- 7. a paper containing an indicator that turns red when exposed to an acid and blue when exposed to a base
- 9. bases that dissolve in water
- 10. chemical substances that result from a chemical reaction mass of the products
- 11. a bond that forms between the atoms in a molecule
