Calcium carbonate combines with Hydrochloric acid to produce calcium chloride, water and carbon dioxide gas
The balanced chemical equation for the reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl) is:
CaCO3 + 2HCl → CaCl2 + H2O + CO2
This reaction shows that one molecule of calcium carbonate combines with two molecules of hydrochloric acid to form one molecule of calcium chloride, one molecule of water, and one molecule of carbon dioxide gas.
