A car bumper is to be chrome plated. The bumper is dipped into an acidic solution of dichromate. The bumper serves
as the cathode in an electrolytic cell. Oxidation of H2O occurs at the anode.
a. how many moles of O2 gas will evolve for every 1.00 x10^2 g of Cr(s) deposited onto the bumper
b. If the current is 10.0 amperes, how long will it take to deposit 1.00 x10^2 g of Cr(s) onto the bumper
