WebbPurpose: To use simple calorimeter to calculate the molar enthalpy of combustion, Δ c H m, for paraffin (candle wax), C 25 H 52(s), ethanol, or methanol fuels Background: In this experiment you will determine how much heat is released. We find that energy is needed to break chemical bonds and that energy is released when chemical bonds form. WebbThe standard enthalpy of combustion of methanol including uncertainty is: 24.59 kJ/mol ± 3.60 kJ/mol The same procedures were made for the other 4 alcohols to calculate the standard enthalpy of combustion of alcohols including uncertainties and the results were put into the table on the next page. Conclusion:
