Answer :
The heat produced from the complete combustion of methane is 1,664.59 kJ.
The chemical energy from the combustion reaction is converted into thermal energy. The thermal energy or heat produced by a mole of a substance, methane, would be the same as the enthalpy of reaction/combustion.
First, we need to determine the number of moles of methane. As stated in the problem, complete combustion is achieved for 30.0g of methane. The molecular weight (MW) of methane is 16.04 g/mol.
Mole methane= mass methane/MW methane
Mol methane= 30 g / 16.04 g/mol
Mol methane= 1.87 mol
We can now multiply it by the given enthalpy of the reaction to determine the heat produced.
Heat produced= enthalpy of reaction * mol methane
Heat produced= 890 kJ/mol * 1.87 mol
Heat produced= 1,664.59 kJ
