Question
There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide:
2Cu2S(s)+3O2(g) --> 2Cu2O(s)+2SO2(g)
In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide:
Cu2O(s)+C(s) --> 2Cu(s)+CO(g)
Write the net chemical equation for the production of copper from copper(I) sulfide, oxygen, and carbon. Be sure your equation is balanced.
