Answer 1

Explanation:

Reaction with calcium carbonate.Calcium carbonate reacts with acids to produce a calcium salt, water and carbon dioxide: calcium carbonate +hydrochloric acid → calcium chloride + water + carbon dioxide.

HCl + CaCo3 ➡️ CaCl2 + H2O + CO2

Answer 2

Answer:

Chalk plus hydrochloric acid give calcium chloride, carbon dioxide and water.

Explanation:

CaCO3 + 2HCl→CaCl2 + CO2+ H2O
