Reaction sequence stoichiometry
In the second step, copper(1) oxide and carbon react to form copper and carbon monoxide:
Cu₂O(s) + C(s)→ 2Cu(s) + CO(g)
There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(1) sulfide and oxygen react to form copper(1) oxide
and sulfur dioxide:
2Cu₂S (s) + 30₂(g) → 2Cu₂0(s) + 250, (g)
Suppose the yield of the first step is 91.% and the yield of the second step is 78.%. Calculate the mass of oxygen required to make 3.0 kg of copper.
Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.
