Answer 2

Hi mate here is ur answer

When copper nail is dipped in copper sulphate solution then iron is more reactive than copper, so it displaces copper from copper sulphate solution.

Fe+CuSO4. --------- FeSO4+ Cu.

When sodium react with oxygen

4Na+ O2 -------- 2Na2O.

When Aluminum react with HCl.

2Al+ 6HCl -------- 2AlCl3+ 3H2.
