Copper has been used for thousands of years, either as a pure metal or in alloys. It is frequently used today in the production of wires and cables. Copper can be obtained through smelting or recycling. Determine the energy associated with each of these processes in order to recycle 1.00 mol Cu. The smelting of copper occurs by the balanced chemical equation CuO(s) +CO(g)- Cu(s) +CO, (g) where ?? c o is- 155 kJ mol. Assume the process of recycling...
