Question #54277

Acid rain often contains sulfuric acid, ${H}_{2} S {O}_{4}$, which will react with the calcium carbonate, $C a C {O}_{3}$, to produce relatively insoluble calcium sulfate, $C a S {O}_{4}$, carbon dioxide, $C {O}_{2}$, and water, ${H}_{2} O$.
$C a C {O}_{3 \left(s\right)} + {H}_{2} S {O}_{4 \left(a q\right)} \to C a S {O}_{4 \left(s\right)} + C {O}_{2 \left(g\right)} + {H}_{2} {O}_{\left(l\right)}$
