Answer 1

Answer:

A. zinc sulphate is formed

B. Calcium hydroxide is formed

C.Mercury metal

D. Copper

E. NaCl and BaSo4

Answer 2

Answer:

1 Displacement Reaction

2 Exothermic Reaction and Combination Reaction

3 Decomposition Reaction

4 Displacement Reaction

5 Double Displacement Reaction

Explanation:

1 Zn +H2SO4 = ZnSO4+H2

2 CaO+H2O=Ca(OH)2+Heat

3 HgO+Heat=Hg2 +O2

4 H2+CuO=H2O+Cu

5 NaSO4+BaCl2=NaCl+BaSO4
