Consider an electrochemical cell constructed from the following half cells, linked by an external circuit and by a KCl salt bridge. - an Al(s) electrode in 1.0 M Al(NO3)3 solution - a Pb(s) electrode in 1.0 M Pb(NO3)2 solution The balanced overall (net) cell reaction is A) Pb(s) + Al3+(aq) → Pb2+(aq) + Al(s). B) 3Pb(s) + 2Al3+(aq) → 3Pb2+(aq) + 2Al(s). C) 3Pb2+(aq) + 2Al(s) → 3Pb(s) + 2Al3+(aq). D) Pb2+(aq) + Al(s) → Pb(s) + Al3+(aq).
