question 61

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) + O₂(g) → 2 CuO(s) + S(s)
• E) Cu₂S(l) + O₂(g) → 2 Cu(l) + SO₂(g)
