Question 1

The specific heat of copper is 0.385 J g-1 K-1. If 34.2 g of copper, initially at 21.0 °C, absorbs 4.689 kJ, what will be the final temperature of the copper?
◦ 21.4 °C
◦ 23.8 °C
◦ 356 °C
◦ 377 °C

Question 2

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:
◦ Cu(s) + S(s) + 5 H2O(g) + 2 O2(g) → CuSO4 ∙ 5 H2O(s)
◦ Cu(s) + S(s) + 9/2 O2(g) + 5 H2(g) → CuSO4 ∙ 5 H2O(s)
◦ Cu(s) + SO4(g) + 5 H2O(g) → CuSO4 ∙ 5 H2O(s)
◦ Cu(s) + S(s) + 5/9 O2(g) + 5 H2(g) → CuSO4 ∙ 5 H2O(s)
◦ 2 Cu(s) + 2 SO2(g) + 5 H2O(g) → 2 CuSO4 ∙ 5 H2O(s)
