3. What is the balanced equation for the galvanic cell reaction expressed using shorthand notation below? Ni(s) | Ni2+(aq) || Cl2(g) | Cl-(aq) | C(s) a) Ni(s) + 2 Cl-(aq) → Ni2+(aq) + Cl2(g) b) Ni2+(aq) + 2 Cl-(aq) → NiCl2(s) c) Ni2+(aq) + 2 Cl-(aq) → Ni(s) + Cl2(g) d) Ni(s) + Cl2(g) → Ni2+(aq) + 2 Cl-(aq)
