Enter your answer in the provided box. A constant current is passed through an electrolytic cell containing molten MgCl2 for 13.0 h. If 9.80 ×105 g of Cl2 are obtained, what is the current in amperes?
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?
Question 16 (5 points) A constant current of 0.912 A is passed through an electrolytic cell containing molten MgCl2 for 7.25 h. What mass of Mg is produced? Faraday constant, 95485 C mol-1 Molar mass Mg 24.31 g/mol MgCl2 95.21 g/mol
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.
