Omar observes that many buildings in his city were built using limestone. He has read that acid rain can damage limestone. He also knows that limestone reacts with acids and that chemical reactions are affected by temperature. With this in mind, he conducts an investigation to see how the amount of damage to the limestone is affected by the amount of acid on the stone.

The most common acid rain is in the form of sulfuric acid (H2SO4). Lime stone has the chemical formula of CaCO3. Sulfuric acid plus limestone will yield to water, carbon dioxide calcium sulfate. The chemical reaction for this is : H2SO4 + CaCO3 > H2O + CO2 + CaSO4. The amount of damage can be done is proportional to the amount of acid. One mole of acid will react with one mole of the limestone.
