Question
A voltaic cell prepared using zinc and iodine has the cell notation Zn(s) | Zn2+(aq) || 1-1(aq) | 12(s) |C(graphite). Which of the following equations correctly
represents the balanced, spontaneous cell reaction?
12(s) + Zn(s) → 21-1(aq) + Zn²*(aq)
O 21r*(aq) -
+ Zn2*(aq)
12(s) + Zn(s)
none of the choices
12(s) + Zn2*(aq) –→ 211(aq) + Zn(s)
O Zn(s) + 21(aq) → Zn2*(aq) + 12(s)
