Answer 1

Answer:

1 question is incomplete

2 HCL is correct answer

Answer 2

Answer:

(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 carbondioxide.

(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
