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.
