What mass of each of the following substances can be produced in 1.0 h with a current of 15 A? a. Co from aqueous Co2+ c. I2 from aqueous KI b. Hf from aqueous Hf4+ d. Cr from molten CrO3 What volume of F2 gas, at 25oC and 1.00 atm, is produced when molten KF is electrolyzed by a current of 10.0 A for 2.00 h? What mass of potassium metal is produced? At which electrode does each reaction occur? What is the maximum work that can be obtained from a hydrogen– oxygen fuel cell at standard conditions that produces 1.00 kg of water at 25oC? Why do we say that this is the maximum work that can be obtained? What are the ...Consider the following reduction potentials: Co3+ + 3e– → Co ϐo = 1.26 V Co2+ + 2e– → Co ϐo = 20.28 V a. When cobalt metal dissolves in 1.0 M nitric acid, will Co3+ or Co2+ be the primary product (assuming ...
