Question 144

A geologist is assessing the environmental hazards of acid rain, containing dilute nitric acid, falling on a limestone landscape (predominantly calcium carbonate).

Calcium nitrate, carbon dioxide, and water are formed during this weathering process.

Complete and balance the equation for this reaction.

CaCO3+…HNO3→……⋯+……⋯+……… \text{CaCO}_3 + \dots\text{HNO}_3 \rightarrow \dots\dots\dots + \dots\dots\dots + \dots\dots\dots CaCO3​+…HNO3​→……⋯+……⋯+………
