question 32

Multiple Choice

Write a balanced equation for the reaction of concentrated sulfuric acid with copper metal.Assume two products are sulfur dioxide and Cu²⁺.

• A) Cu(s)+ SO₄²⁻(aq)→ Cu²⁺(aq)+ O₂(g)+ SO₂(g)
• B) Cu(s)+ 4H⁺(aq)+ SO₄²⁻(aq)→ CuS(s)+ 2O₂(g)
• C) Cu(s)+ 2H⁺(aq)+ SO₄²⁻(aq)→ Cu²⁺(aq)+ H₂O(l)+ SO₂(g)
• D) Cu(s)+ 4H⁺(aq)+ SO₄²⁻(aq)→ Cu²⁺(aq)+ 2H₂O(l)+ SO₂(g)
• E) Cu(s)+ 8H⁺(aq)+ SO₄²⁻(aq)→ Cu²⁺(aq)+ 4H₂O(l)+ S(g)
