E. The "Zebra" cell was invented in 1985 in South Africa as part of the "ZEolite 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 E^o for the Zebra cell?................... 2.Are the reactants in this battery at room temperature when it is operating? Explain how you know.
In N2O, nitrogen is the central atom and the oxygen atom is terminal. In OF2, however, oxygen is the central atom.Use formal charges to explain why.
