A good example of a decomposition reaction occurs when baking soda is heated. The reaction equation is as follows:

2 NaHCO3 --> Na2CO3 + CO2 + H2O

The reaction is a decomposition reaction because one compound, sodium bicarbonate, spontaneously breaks apart into multiple compounds, sodium carbonate, water, and carbon dioxide.
