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 E°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 “rebar.” 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.
G.) How many grams of copper can be reduced (plated out) by applying a 4.00 amp current for 53.0 minutes to a solution containing Cu2+ ions?
