Combustion of Alkanols Aim: To determine which alkanols has higher heat combustion Hypothesis: The alkanols with the longer carbon chain will a higher heat combustion Background Information: Heat combustion can be calculated by using various formulas. By using ΔH= -mcΔT‚ we can gather the amount of heat released. Since the experiment is exothermic‚ ΔH will have a negative value. By dividing the total amount by 1000‚ the units changes into KJ. Divide the total KJ of heat by the amount of fuel

experiment is to determine which fuel‚ out of Pentane‚ Propane-1-ol and Propane-2-ol would be the most appropriate to take on a camping trip to a national park where wood cannot be used to burn. Factors that need to be considered are: • Heat of combustion (flash point) • Heat of vaporisation (boiling point) • How long the fuel will last • Does the fuel heat up the water relatively quickly • Does the fuel combust completely Hypothesis: If the tests are all successful‚ Pentane should produce a larger

(limewater) 50 mL beaker (for indicator) Procedure My lab partner and I performed a series of experiments to investigate the chemistry of the burning of a candle. The teacher provided the following chemical equation to describe the burning‚ or combustion‚ in the candle: Hydrocarbon fuel + O2 CO2 + H2O The candle we used was a small‚ white emergency candle about 3.5 cm tall. The candle had already been used by someone else because I could see from the black wick that it had been lit before.
