Question

please check if my answers are correct

Suppose a powerful battery is connected between a pair of inert graphite electrodes dipped into a pot of molten magnesium iodide (MgI,) (see sketch at right). 7° The battery makes a current of electrons flow in the directions shown by the arrows in the sketch. Note: Group 1A and Group 2A metals all melt at temperatures lower than their salts. A В O A Which electrode is the cathode? O B Write a balanced equation for the half-reaction that takes 21 (1) - I, (g) + 2e place at electrode A. Write a balanced equation for the overall reaction. Mg*(1) + 21 (1) → Mg(!) + I, (3)
