In the presence of excess oxygen, methane gas burns in a constant-pressure system to yield carbon dioxide and water:

CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (l) ΔrH = -890.0 kJ

Calculate the value of q (kJ) in this exothermic reaction when 1.90 g of methane is combusted at constant pressure.

▸ -105.7 kJ

▸ 0.0342 kJ

▸ -0.0095 kJ

▸ 29.3 kJ

▸ -1.06 × 105 kJ
