Assignment:
Consider the following reaction.
CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) ΔH = -891 kJ
Calculate the enthalpy change for each of the following cases.
(a) 3.00 g methane is burned in excess oxygen.
(b) 3.00 x 103 L methane gas at 738 torr and 21°C is burned in excess
Provide complete and step by step solution for the question and show calculations and use formulas.
