Question

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 copper is simplified to ust the melting of the solid Cu starting at 25 C. The melting point of Cu is 1084.5°C with ? Hefus-130 kJ/mol and a molar heat capacity, CpCu-24.5 Jimolc. Part 1 (0.5 point) See Periodic Table See Hint Enthalpy change for the reaction recovering Cu from Cuo kJ Part 2 (0.5 point) Energy for recycling Cu
