Answer 1

Dear Student,


$$\begin{gathered} \mathrm{The}\mathrm{reaction}\mathrm{of}\mathrm{calcium}\mathrm{carbonate}\mathrm{with}\mathrm{dil}.\mathrm{HCl}\mathrm{is}\mathrm{shown}\mathrm{below}: \\ {\mathrm{CaCO}}_3+\hspace{0.17em}2\mathrm{HCl}\to {\mathrm{CaCl}}_2+{\mathrm{CO}}_2+\hspace{0.17em}{\mathrm{H}}_2\mathrm{O} \\ \mathrm{Hence},\mathrm{the}\mathrm{gas}\mathrm{evolved}\mathrm{is}\mathrm{carbon}\mathrm{dioxide}. \end{gathered}$$
