question 57

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)
