Decomposition Reaction:

In decomposition reaction, a compound breaks into two or more substances. This kind of reaction generally happens when a compound is heated or electricity is passed through it. For example, when we heat calcium carbonate, calcium oxide and carbon dioxide are produced. Similarly, when electricity is passed through a mixture of water and sulphuric acid, then hydrogen and oxygen gases are produced.
