Which one of the following reactions must be carried out in an electrolytic cell rather than in a galvanic cell? O H₂(g) + 12(s) → 2H*(aq) + 21 (aq) Fe²+ (aq) + Mg(s) → Fe(s) + Mg²+ (aq) O 2Al(s) + 3Fe²+ (aq) → 2Al³+ (aq) + 3Fe(s) Zn²+ (aq) + Ca(s) → Zn(s) + Ca²+ (aq) Al³+ (aq) + 3Br (aq) → Al(s) + (3/2)Br₂(1)
