Explanation:
(a) Combination reaction : Cao+CO
2
→CaCO
3
, in this reaction calcium oxide is combines with carbon dioxide to form calcium carbonate.
(b) Decomposition reaction : CaCO
3
→CaO+CO
2
, in this reaction calcium carbonate is decomposed to calcium oxide and carbon dioxide.
(c) Displacement reaction : Fe(s)+CuSO
4
(aq.)→FeSO
4
(aq)+Cu(s), in this reaction Fe displaces copper to form ferric sulphate.
(d) Analysis reaction : 2H
2
O→2H
2
+O
2
Hence, the correct option is C
