Multiple Choice
The standard enthalpy of formation for CuSO4 ∙ 5 H2O(s) is -2278.0 kJ/mol at 25 °C.The chemical equation to which this value applies is:
A) Cu(s) + S(s) + 5 H2O(g) + 2 O2(g) → CuSO4 ∙ 5 H2O(s)
B) Cu(s) + S(s) + 9/2 O2(g) + 5 H2(g) → CuSO4 ∙ 5 H2O(s)
C) Cu(s) + SO4(g) + 5 H2O(g) → CuSO4 ∙ 5 H2O(s)
D) Cu(s) + S(s) + 5/9 O2(g) + 5 H2(g) → CuSO4 ∙ 5 H2O(s)
E) 2 Cu(s) + 2 SO2(g) + 5 H2O(g) → 2 CuSO4 ∙ 5 H2O(s)
