The reaction of methane combustion proceeds according to the equation: CH4 + 2O2 = CO2 + 2H2O + 891.3 kJ

The reaction of methane combustion proceeds according to the equation: CH4 + 2O2 = CO2 + 2H2O + 891.3 kJ How much heat will be released during the combustion of 100 liters of methane.

1) We count moths. According to this equation, we have 1 mole of methane, then we calculate how many mole of methane will be when it burns with a volume of 100 liters.
n (CH4) = 100l / 22.4l / mol = 4.464mol
2) We make the proportion
If 1 mol is 891.3 kJ, then 4.464 mol is 3979 kJ.
Answer: 3979kJ
