Twо hаlf-cells аre shоwn belоw: Fe2+(аq)  +  2e-   ↔  Fe(s)     Ecell = - 0.44 V Cu2+(aq)  +  2e-  ↔  Cu(s)    Ecell = +0.34 V Hint: The half-cell with the highest positive potential gets reduced. the other half-cell must get oxidized. Based on the cell voltage you received for question 21, what can you say about this cell?
