Answer

Brief Explanations:

  • A gas production (bubbling) indicates new substances are formed, which is a sign of chemical change.
  • A change in composition of reactants means a chemical reaction has taken place. Dissolving alone may be a physical change, and color - change is not a definitive sign for this reaction.

Answer:

A. A gas is produced, C. Bubbling occurred, E. There is a change in the composition of the reactants
