The standard enthalpy of combustion for methane is -890 kJ/mol.
The molar heat of combustion of octanol is 5294
Let's think about what happens in the combustion of methane. Take natural gas for example (methane) used to heat homes, or used in stoves. The product is heat, therefore heat is given off. Therefore EXOTHERMIC.
Natural gas is not just one type of hyrdocarbon, and so its heat of combustion (or enthalpy of combustion) will vary from sources. However, it is primarily formed from methane which has a "heat of combustion" of 889 Kilojoules per mole, you could use that value. Hope that's what you wanted!
The molar heat of combustion of pentanol is 3329 kJ mol-1 according to http://www.creative-chemistry.org.uk/gcse/documents/Module7/N-m07-24.pdf
Reaction of combustion of methane will give off lot of energy. In any combustion reaction there will always be formation of water vapor and heat. Methane + oxygen = combustion reaction.
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
The molar heat of combustion of octanol is 5294
The molar heat of combustion of methane (890 kJ/mol) is higher than that of water gas (525 kJ/mol)
You think probable to molar heat, expressed in J/mol.
Let's think about what happens in the combustion of methane. Take natural gas for example (methane) used to heat homes, or used in stoves. The product is heat, therefore heat is given off. Therefore EXOTHERMIC.
Molar heat of combustion of ethanol = -1366.8 kJ/mol C2H5OH
CH4 + 2O2 → CO2 + 2H2O + Energy (Heat) Methane + Oxygen → Carbon Dioxide + Water and Energy (Heat)

methane rapidly combines with oxygen to form carbon dioxide and water, releasing lots of heat. it's called combustion.-------------------------------------------------------------------------CH4 + 2O2 = CO2 + 2H2O + heat
Exothermic chemical reactions release energy in the form of heat and sometimes light. A common example would be the combustion (oxidation) of methane*:Methane: CH4 + 2O2 -----> CO2 + 2H2O + Energy (heat and light)* The combustion of methane (natural gas) is commonly used to heat water, cook, and to heat homes.
