If O_2 from the air comes in contact with hot lead sulfide, it is possible that the sulfide will be oxidized to PbO. The most common mineral containing lead is a sulfide which is identical with the sulfide you prepared. In the extraction of lead from this mineral, the sulfide is first heated in a limited supply of air to give lead(II)oxide, PbO; the sulfur is converted into gaseous 〖SO〗_2. The PbO is then reduced by carbon to give metallic lead and carbon monoxide. Write balanced equations for these reactions.
Please explain step by step.
Thank You

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:2 Cu_2 S(s)+3 O_2(g) rightarrow 2 Cu_2 O(s)+2 SO_2(g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Cu_2 O(s)+ C(s) rightarrow 2 Cu(s)+ CO(g) Write the net chemical equation for the production of copper from copper(I) sulfide, oxygen and carbon. Be sure your...
