Given the following cell diagram,
Al(s) | Al3+(aq) || Cd2+(aq) | Cd (s)
what is the balanced overall (net) cell reaction?
◦ Al(s) + Cd2+(aq) → Al3+(aq) + Cd (s)
◦ Al3+(aq) + Cd (s) → Al(s) + Cd2+(aq)
◦ 2Al(s) + 3Cd2+(aq) → 2Al3+(aq) + 3Cd (s)
◦ 2Al3+(aq) + 3Cd (s) → 2Al(s) + 3Cd2+(aq)
◦ 3Al3+(aq) + 2Cd (s) → 3Al(s) + 2Cd2+(aq)
