A magnesium rod with a mass of 6 kg is connected to an iron pipe
where it is to act as a sacrificial anode. A current with an
average power of 220 A passes through the rod and the tube.
a. Write a reaction equation for the half-reaction (an
oxidation) that takes place at the magnesium rod. Write the
reaction equation for the half-reaction (a reduction) that takes
place on the surface of the iron pipe. In which direction do the
electrons go between the two surfaces?
b. How many years does it take before the whole magnesium rod is
consumed
