a) The elemental calcium (Ca) is produced by the electrolysis of molten CaCl2. Explain how many pounds of calcium can be obtained if current is applied for 48 h 6.5x103 A? Presume a cell efficiency of 70%.
b) Explain two electrolytic cells connected in series. Knowing that one of them is deposited 0.50 g of silver (Ag) from a solution of AgNO3, compute the mass of chromium (Cr) is deposited on the cathode of another cell from a solution of Cr (NO3) 3.
