Prove N=10pd/E

Identify the reactant oxidized and the reactant reduced in the following equations;

1. Cl₂(g) + 2 K(s) → 2 KCl(s)
2. FeSO4(aq) + Mg(s) → Fe(s) + MgSO4(aq)
3. Ni_(s) + Pb²⁺_(aq) →Pb_(s) + Ni²⁺_(aq)

write the corresponding half reaction for

(a)  Ca(s) + Cu(NO3)2(aq) → Cu(s) + Ca(NO3)2(aq)

(b)  Zn(s) + Ni²⁺ → Ni(s) + Zn²⁺
