Question

When Acid Rain falls on limestone, the rock is eroded and carbon dioxide is produced.

Write a balanced equation for the reaction between calcium carbonate and nitric acid.

Answer 1

The formula of calcium carbonate is CaCO3

The formula of nitric acid is HNO3.

When put together:

CaCO3 + HNO3 = Ca(NO3)2 + CO2 + H2O

The balanced equation:

CaCO3 + 2HNO3 = Ca(NO3)2 + CO2 + H2O
