Decomposition Reactions

Decomposition Reactions

 

chemical reactions in which two or more substances are formed from a single substance. For example, mercuric oxide decomposes into mercury and oxygen upon heating: 2HgO = 2Hg + O2; silver chloride decomposes to yield silver and chlorine upon exposure to light: 2AgCl = 2Ag + Cl2. An industrially important decomposition reaction is the pyrolysis of many hydrocarbons and their derivatives.
