A battery is constructed based on the oxidation of magnesium and the reduction of Cu^2+. The initial concentrations of Mg^2+ and Cu^2+ are 1.2×10?4M and 1.6M, respectively, in 1.0-liter half-cells.
What is the initial voltage of the battery? V=
What is the voltage of the battery after delivering 4.7A for 8.0hours? V=
How long can the battery deliver 4.7A before going dead? t=
