2. A decomposition reaction is a type of chemical reaction  in which a single compound breaks down into two or more elements or new compounds.
These  reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds.
This reaction is usually endothermic because heat is required to break the bonds present in the substance.
e.g., CaCO3HeatCaO+CO2 2 H2OElectricity2 H2 + O2
