Question 1

How much heat is absorbed/released when 10.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(l) according to the following chemical equation?

4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l)ΔH° = +1168 kJ

◦ 171.5 kJ of heat are released.
◦ 686.0 kJ of heat are released.
◦ 171.5 kJ of heat are absorbed.
◦ 686.0 kJ of heat are absorbed.

Question 2

How much heat is absorbed when 20.00 g of C(s) reacts in the presence of excess SO2(g) to produce CS2(l) and CO(g) according to the following chemical equation?

5 C(s) + 2 SO2(g) → CS2(l) + 4 CO(g)ΔH° = +239.9 kJ

◦ 159.9 kJ
◦ 79.97 kJ
◦ 959.3 kJ
◦ 399.5 kJ
