Explanation:
Detailed explanation-1: -Therefore, the reaction CaCO 3 ( s ) Calcium carbonate → CaO ( s ) Calcium oxide + CO 2 ( g ) Carbon dioxide is a decomposition reaction.
Detailed explanation-2: -2Ca(s) + O2(g) → 2CaO(s) is a redox reaction since the oxidation number of Ca changes from 0 to +2 and the oxidation number of O changes from 0 to-2 during the reaction and the reaction does not involve the transfer of hydrogen during the reaction, that means it is not an acid-base reaction.
Detailed explanation-3: -Complete answer: A . $CaCO 3
