Heat of combustion Aim I Aim to find how much energy is produced when burning different alcohols. To do this I will heat a beaker of water by burning alcohols. I will burn five different alcohols, methanol, ethanol, propanol, butanol and pentanol. I will also use these results to predict the heat of combustion of hexonal. Prediction I predict that all the experiments will be exothermic. This is because there are more bonds formed that there are made and bond forming is an exothermic process. I think that the more carbon atoms each alcohol has the higher energy per mole the more heat given out Theory The reaction that is involved in burning alcohols is exothermic because heat is given out. The formulae of the alcohols that I will be using are... · Methanol C1H3 OH · Ethanol C2 H5 OH · Propanol C3 H7 OH · Butanol C 4H9 OH · Pentanol C5 H 11OH Amount of bond energy...
