Copper was one of the first metals used by humans because it can be recovered from several copper minerals including cuprite (Cu2O), chalcocite (Cu2S), and malachite [Cu2CO3(OH)2]. Balance the following reactions for converting these minerals into copper metal: (A) Cu2O(s) + C(s) → Cu(s) + CO2(g) (B) Cu2O(s) + Cu2S(s) → Cu(s) + SO2(g) (C) Cu2CO3(OH)2(s) + C(s) → Cu(s) + CO2(g) + H2O(g)
11 Question (3 points) See page 247 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 145 mol Cu The smelting of copper occurs by the balanced chemical equation: Cuo(4) + CO(g) – Cu(s) + CO,(g) where AH cuois -155...
