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: (s)(g)(s)(g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: (s)(s)(s)(g) Write the net chemical equation for the production of copper from copper(I) sulfide, oxygen and carbon. Be sure your equation is balanced.

The net chemical equation is

Explanation:

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Every balanced chemical equation follows law of conservation of mass.

The balanced chemical equation for Step 1 process of the reaction:

Step 1:  

The balanced chemical equation for Step 2 process of the reaction:

Step 2:  

The net chemical equation for the formation of copper from copper(I) sulfide, oxygen and carbon follows:

Hence, the net chemical equation is written above.
