An empty 3.70 L steel vessel is filled with 2.00 atm of CH4(g)
and 8.00 atm of O2(g) at 300 ∘C. A spark causes the CH4 to burn
completely, according to the equation:
CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔH∘ = -802kJ
1. What is the final temperature inside the vessel after combustion, assuming that the steel vessel has a mass of 12.475 kg , the mixture of gases has an average molar heat capacity of 21J/(mol⋅∘C), and the heat capacity of steel is 0.499J/(g⋅∘C)?
2. What is the partial pressure of CO2(g) in the vessel after combustion?

You are given a steel vessel containing a mixture of methane gas (CH4 (g)) and propane gas (C3H8 (g)). You completely combust this entire mixture in the presence of excess oxygen gas, and you collect all of the carbon dioxide and water formed in the combustion reaction. A total of 48.4 grams of CO2 and 32.4 grams of H2O are collected. Determine the number of moles of CH4 (g) and C3H8 (g) that were present in the initial mixture.
