Answer

Brief Explanations:

  1. In general, acids can be represented as HX where H is hydrogen and X is an anion. HOH is water, ZOH is not a common general - acid formula.
  2. Bases have a pH greater than 7. A pH of 7 is neutral and less than 7 is acidic.
  3. When acids react with metals, hydrogen gas is produced. Reaction of an acid and a base produces water and a salt, and acids do not react with metals to produce bases.

Answer:

  1. B. HX
  2. C. greater than 7
  3. B. hydrogen gas
