Combustion reaction involves the release of energy.
Calculate the heat energy energy released in J/g if the standard enthalpy of combution of butane is 2658KJ/mol according to following combustion reaction C4H10+13/2O2-- 4CO2+5H2O
Delta cH*= -2658.0 KJ/mol
The amount of energy released during the combustion of a unit mass of fuel is called____.
