As CaCO3 s decomposed into smaller fragments, CaO and CO2 hence this is decomposition reaction Chemical decomposition, analysis or breakdown is the separation of a chemical compound into elements or simpler compounds. It is sometimes defined as the exact opposite of chemical synthesis. Hence, the correct option is E
