Write the Overall Equation for Reducing Cu₂S to Metallic Copper

Multiple Choice

Write the overall equation for reducing Cu₂S to metallic copper.

A) Cu₂S(l) + C(s) → 2 Cu(l) + CS(g)
B) Cu₂S(l) + CO(g) → 2 Cu(l) + CO(g) + S(s)
C) Cu₂S(l) + 2 CO(g) + O₂(g) → 2 Cu(l) + 2 CO₂(g) + S(s)
D) Cu₂S(l) + 3 O₂(g) → 2 Cu(l) + S(s) + 2 O₃(g)
E) Cu₂S(l) + O₂(g) → 2 Cu(l) + SO₂(g)
