E. The Zebra cell was invented in 1985 in South Africa as part of the Eolite Battery Research Africa project, and is used in all-electric municipal buses and other vehicles. It uses nickel and molten sodium as its electrodes. Its overall cell reaction is

NiCl2(l) + 2Na(l) <--> Ni(s) + 2NaCl(l)

1.What is the Eo for the Zebra cell?

2.Are the reactants in this battery at room temperature when it is operating? Explain how you know.

F. Concrete used in road construction is reinforced using steel bars in a grid, known collectively as After many years, rebar will begin to corrode, and the concrete will weaken. Studies are ongoing regarding the best metal to be a sacrificial anode to prevent corrosion of the rebar. Which would work better for the purpose, magnesium or zinc? Explain your answer based on the oxidation potentials for each metal.
