"WebCalculate the enthalpy change by dividing Q by the number of moles. Remember to convert energy in J to kJ. Energy change = 15.466 kJ / 0.043 mol = 359.67 kJ/mol Since this is a combustion reaction, we need to remember that it is an exothermic reaction and add a negative sign. Our final answer = -359.67 kJ/mol " - Temperature change practical
