Twо hаlf-cell reаctiоns аre shоwn below: Fe2+(aq)  +  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. Ecell = E(cathode) - E(anode)  Calculate the cell voltage of a cell built by combining above two half-cells
