Question

1. Cuso,(aq) + Fe (s)
2 CuSo,(aq) + Pb(s)​

Answer 1

Answer:

1.

CuSo4(aq) + 2 Fe(s) = Fe2(So4)3(aq) + 3 Cu(s

2.

CuS + PbSO4 → PbS + CuSO4

Answer 2

Answer and Explanation:

Since Fe (Iron) is more reactive than Cu (Copper), it can displace Cu from its salt solution that is, Fe can displace Cu from CuSO₄ solution

Hence,

CuSO₄ + Fe -------> FeSO₄ + Cu

Since Pb (Lead) is more reactive than Cu (Copper), it can displace Cu from its salt solution that is, Pb can displace Cu from CuSO₄ solution

Hence,

CuSO₄ + Pb -------> PbSO₄ + Cu
