Oxygen Supply in Submarines Nuclear submarines can stay under water nearly indefinitely because they can produce their own oxygen by the electrolysis of water. How many liters of O2 at 298 K and 1.00 bar are produced in 2.00 hr in an electrolytic cell operating at a current of 0.0200 A?

What is the electrical current, in Amperes, that must be applied if 6.50 g Ag is deposited at the cathode in 2.00 hrs during the electrolysis of AgNO3 (aq)? Please show your work

Molten RbCl can be electrolyzed to form metallic Rb. For what duration should an electrolysis be performed at a current of 1.98 A in order to produce 13.4 g Rb?

The anode compartment of a galvanic cell consists of a Zn anode immersed in 0.05M ZnCl2 The cathode compartment consists of a Cu cathode immersed in an 0.10M CuCl2 solution. Using the cell potentials found on page 815 of your textbook, calculate the cell potential for this reaction. Assume T = 298K.
