Here's the decomposition reaction for Group 2 metal carbonates and the temperatures that the salts decompose. We notice that bonds within the carbonate anion are broken to form metal oxide and carbon dioxide.
WebWhen the reaction takes place it is usually endothermic. Heat is required to break the chemical bonds in the compound undergoing decomposition. If decomposition is exothermic, the reaction will occur very fast and possibly result in an explosion.
