It "fizzes". When you put acid on CaCO3 it reacts to release CO2 gas:
CaCO3 + 2H+(aq) -> Ca2+(aq) + H2O + CO2(g)

Calcium carbonate reacts with strong acids such as Hydrochloric acid to give off carbon dioxide and water.
Want to know the balanced equation?
CaCo3 (s) + 2Hcl (aq) ---> CaCl2 (aq) + H2O (l) + CO2 (g)

A simple answer is that the acid (HCl) and the base (CaCO3) neutralize each other.

CaCl2 is formed together with the evolution of a colourless , odourless gas which extinguishes a burning splinter , turns lime water milky and does not have any effect on acidified solution of pottasium dichromate solution . the gas is carbon dioxide( CO2)

this type of reaction is a substitution reaction.
the balanced eq is
CaCO3 +HCl -CaCl2+CO2+H2O
