The yellow beams in the model represent equal amounts of radiation coming from the Sun. Based on information shown in the model,
which statement is false?
A. Sunlight is more spread out at the poles than the equator.
B. The regions near the poles get the most-intense sunlight.
C. Higher latitudes get less-direct sunlight than lower latitudes.
D. The equator gets the most-direct radiation from the Sun.
(PLEASE HELP)

Answer:
-1.05 V
Explanation:
A detailed diagram of the setup as required in the question is shown in the image attached to this answer. The electrolytes chosen are SnCl2 for the anode half cell and MnCl2 for the cathode half cell. Tin rod and manganese rod are used as the anode and cathode materials respectively. Electrons flow from anode to cathode as indicated. The battery connected to the set up drives this non spontaneous electrolytic process.
Oxidation half equation;
Sn(s) ------> Sn^2+(aq) + 2e
Reduction half equation:
Mn^2+(aq) + 2e ----> Mn(s)
Cell voltage= E°cathode - E°anode
E°cathode= -1.19V
E°anode= -0.14 V
Cell voltage= -1.19 V - (-0.14V)
Cell voltage= -1.05 V
