2020-10-15ensp0183enspBalanced chemical equation showing result of strong heating of limestone Explanation The chemical name of lime stone is calcium carbonate. When it is strongly heated it undergoes a chemical process called as thermal decomposition. It leads to the formation of two compounds namely calcium oxide and carbon-di-oxide by breaking of calcium carbonate.
