Solution

(N/A) When dilute hydrochloric acid $(HCl)$ reacts with zinc $(Zn)$,it produces zinc chloride $(ZnCl_2)$ and releases hydrogen gas $(H_2)$.
The chemical equation for this reaction is: $Zn(s) + 2HCl(aq) \rightarrow ZnCl_2(aq) + H_2(g)$.
The gas evolved is hydrogen gas,and its molecular formula is $H_2$.
