The Standard Enthalpy of Formation for CuSO₄ ∙ 5H₂O(s) Is

question 71

Multiple Choice

The standard enthalpy of formation for CuSO₄ ∙ 5H₂O(s) is -2278.0 kJ/mole at 25°C. The chemical equation to which this value applies is:

• A) Cu(s) + S(s) + 5 H₂O(g) + 2 O₂(g) → CuSO₄ ∙ 5H₂O(s)
• B) Cu(s) + S(s) + 9/2 O₂(g) + 5 H₂(g) → CuSO₄ ∙ 5H₂O(s)
• C) Cu(s) + SO₄(g) + 5 H₂O(g) → CuSO₄ ∙ 5H₂O(s)
• D) Cu(s) + S(s) + 5/9 O₂(g) + 5 H₂(g) → CuSO₄ ∙ 5H₂O(s)
• E) 2Cu(s) + 2 SO₂(g) + 5 H₂O(g) → 2CuSO₄ ∙ 5H₂O(s)
