Question:
A zinc-copper battery is constructed as follows:
\[\mathrm{Zn}\left|\mathrm{Zn}^{2+}(0.10 M)ight|\left|\mathrm{Cu}^{2+}(2.50 M)ight| \mathrm{Cu}\]
The mass of each electrode is 200 . \(\mathrm{g}\).
a. Calculate the cell potential when this battery is first connected.
b. Calculate the cell potential after \(10.0 \mathrm{~A}\) of current has flowed for \(10.0 \mathrm{~h}\). (Assume each half-cell contains \(1.00 \mathrm{~L}\) of solution.)
c. Calculate the mass of each electrode after \(10.0 \mathrm{~h}\).
d. How long can this battery deliver a current of 10.0 A before it goes dead?
