How long (hr) must a constant current of 50.0 A be passed through an electrolytic cell containing Color copper metal? Enter your answer with two decimal places and no units. How long (hr) must a constant current of 50.0 A be passed through an electrolytic cell containing aqueous Caders to produce 100 copper metal? Enter your answer with two decimal places and no units.
A constant current is passed through an electrolytic cell containing molten MgCl2 for 11.0 h. If 5.90 × 105 g of Cl2 are obtained, what is the current in amperes?
A current of 0.42A is passed through a similar electrolytic cell set-up containing molten CaCl2 for 2.2 hours. Calcium metal is deposited at the cathode, and chlorine gas is generated and collected at the anode. Write the electrode reactions and calculate the amount of calcium metal (in grams) formed as well as the pressure of chlorine gas (in atm). Assume 330mL of gas was collected at 273K.

Question 17 (10 points) A constant current is passed through a solution of Agt in an electrolytic cell. In 3.0 minutes, 0.65 g of silver is deposited at the cathode. The number of moles of electrons passed into the Agt solution is mole. (Please enter your answer in decimal form, such as 0.021, and keep 2 significant figures.) The total coulombs of charge passed into the Cu2+ solution is C. (Please enter your answer in...
Given the following electrolytic cell:
The current is discharged into the electrolytic cell containing
the solution CuSO4(aq) 1.0M at 25 oC. During
the operation of the cell, copper Cu(s) is deposited on
one electrode and oxygen O2(g) gas is released, near the
second electrode.
O2(g) + 4H3O+(aq) +
4e-
6H2O(l) Eo= 1.23V
