Question

Many stone buildings are made from limestone, which is primarily Valium carbonate. What happens to such buildings over time if they are exposed to acid rain?

Answer 1

They gradually dissolve.

Step-by-step explanation:

The acids in acid rain react with the calcium carbonate.

For example,

CaCO₃ + 2HNO₃ ⟶ Ca(NO₃)₂ + H₂O + CO₂

The soluble calcium salts wash away.

The surfaces of the buildings become eroded and carved details gradually disappear.
