  5. 7. reactant a reactant that is used up first in a chemical reaction
  6. 9. describes a solution that has as much solute as the solvent can dissolve under the conditions
  7. 11. a substance that produces hydroxide ions (OH-) when dissolved in water
  8. 12. describes a chemical reaction that uses more energy than it releases
