Causes of Chemical ReactionsCauses of chemical reactions can often be applied heat or oxidation.

Single Displacement

Calcium Carbonate and Sulfurous AcidAtmospheric sulfur dioxide combines with rainwater to create sulfurous acid. The primary component of marble is calcium carbonate (CaCO3). The sulfurous acid reacts with the CaCO3 in the marble and dissolves it.
