Answer 1

${\mathtt{\huge{\red{\underline{Hey \: Mate \: !!}}}}}$

Like all metal carbonates, calcium carbonate reacts with acidic solutions to produce carbon dioxide gas. It is this reaction that is responsible for limestone fizzing when dilute hydrochloric acid is placed on its surface.♥

Answer 2

Answer:

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

So the gas is carbon dioxide.
