1 What is the complete chemical equation for the red-ox process occurring in magnesium-iron galvanic cell along with the oxidation and reduction half-cell reactions for each electrode using proper chemical notation?
2. Based on the half-cell reaction what happens to each of the electrodes in-terms of their mass?
3. Discuss the direction of the electron flow in the magnesium-iron voltaic cell.
4. Calculate cell potential of magnesium-iron voltaic cell applying E°cell = E°cathode - E°anode
