Solution

(a) Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.
(b)
(i) $Z n + C u S O_{4} ⟶ Z n S O_{4} + C u$ . So, the product A in the reaction is $Z n S O_{4}$ .
(ii) ${N a}_{2} S O_{4} + B a {C l}_{2} ⟶ B a S O_{4} + 2 N a C l$ . The product A in the reaction is $B a S O_{4}$ .
