Án important source of copper is from the copper ore, chalcocite, a form of copper(I) sulfide. When heated, the Cu2S decomposes to form copper and sulfur described by the following equation: Cu2S(s) → Cu(s) + S(s) (13) Determine AG° for the decomposition of CuzS(s). (use data from Appendix G) (14) The reaction of sulfur with oxygen gas yields sulfur dioxide as the only product. Write an equation that describes this reaction, and determine AG° for the process. (use data from Appendix G) (15) The production of copper from chalcocite is performed by roasting the Cu2S in air to produce the metal copper. By combining the equations from (13) and (14), write the equation that describes the roasting of the Cu2S, and explain why coupling these reactions together makes for a more efficient process for the production of the copper (no calculations!).
