- 5. substance that produces H3O+ when dissolved in water
- 8. insoluble product that forms from reaction of soluble reactants
- 9. symbolic representation of a chemical reaction
- 10. vigorous redox reaction producing significant amounts of energy in the form of heat and, sometimes, light
- 12. measure of the efficiency of a reaction, expressed as a percentage of the theoretical yield
- 13. substance formed by a chemical or physical change; shown on the right side of the arrow in a chemical equation
