How does calcium carbonate react with hydrochloric acid?

John McCann answered

CaCO3 + 2HCl --> CaCl2 + CO2 + H2O

------

This reaction produces calcium chloride, carbon dioxide gas and adds water to the already water solution.

Erick Sims answered

CaCO3(s) + 2H+(aq)

The reaction of calcium carbonate with hydrochloric acid is the formation of a gas. The gas formed by these two ingredients being combined is carbon dioxide. The reaction of calcium carbonate and hydrochloric acid also produces calcium chloride and water. An important fact that is shown in this combination is that when the acid and the carbonate combine, they separate from their original bonds. When they form new bonds, the original carbonate and acid no longer exist.
