6. Which one of the following reactions must be carried out in an electrolytic cell rather than in a galvanic cell? (1) Zn²+ (aq) + Ca(s) → Zn(s) + Ca²+ (aq) (3) 2Al(s) + 3Fe²+ (aq) → 2A1³+ (aq) + 3Fe(s) (2) Al³+ (aq) + 3Br (aq) → Al(s) + 3/2 Brz(1) (4) H2(g) + 12(s)→→ 2H*(aq) + 2H(aq) (5) Fe²+ (aq) + Mg(s) → Fe(s) + Mg2+ (aq) 7. An electrochemical cell constructed from the following half cells, linked by a NaNO3 salt bridge. - a Ni electrode in 1.0 M NiCl2 solution - a Ag electrode in 1.0 M AgNO3 solution When the cell is running spontaneously, which statement is correct? (1) The silver electrode loses mass and the silver electrode is the cathode. (2) The silver electrode gains mass and the silver electrode is the cathode. (3) The nickel electrode gains mass and the nickel electrode is the anode. (4) The nickel electrode loses mass and the nickel electrode is the cathode. (5) The nickel electrode gains mass and the nickel electrode is the cathode.
