Consider the electrochemical cell represented below Zn(s)/Zn2+(aq)//Cu2+(aq)/Cu(s). Which of the following equations describes the reaction occurring in the cell?
Cu(s) + Zn2+(aq) →Cu2+(aq) + Zn(s)
Cu(s) + Zn(s) →Cu2+(aq) + Zn2+(aq)
Zn(s) + Cu2+(aq) →Zn2+(aq) + Cu(s)
Zn2+(aq) +Cu2+(aq) → Zn(s) + Cu(s)
