Enter your answer in the provided box. A constant current is passed through an electrolytic cell containing molten MgCl2 for 15.0 h. If 8.70 x 109 g of Cl, are obtained, what is the current in amperes?
• 18.55 A steady current was passed through molten CoSO4 until 2.35 g of metallic cobalt was pro- duced. Calculate the number of coulombs of elec- tricity used. • 18.59 The passage of a current of 0.750 A for 25.0 min deposited 0.369 g of copper from a CuSO4 solution. From this information, calculate the molar mass of copper. 18.87 In a certain electrolysis experiment involving Al+ ions, 60.2 g of Al is recovered when a current of 0.352 A...

Enter your answer in the provided box. Copper is purified by electrolysis. A 1.46 kg anode is used in a cell in which the current is 37.8 A. How long in hours) must the current run to dissolve this anode and electroplate it onto the cathode? h
Enter your answer in the provided box. Repo Copper can be drawn into thin wires. How many meters of 34-gauge wire (diameter- 6.304 10 in) can be produced from the copper in 5.40 Ib of covellite, an ore of copper that is 66.0% copper by mass? (Hint: Treat the wire as a cylindér: V of cylinder = ær²h; d of copper- 8.95 giem'). Gulde
