Science GCSE Coursework Which fuel has the most energy? Aim: The aim of this exercise is to find out, which fuel has the most energy. The fuels that I will be testing are Methanol, Ethanol, Propanol, Butanol and Pentanol. All of these fuels are alcohols. Prediction: I think that Pentanol will be the fuel that will have the most energy. I have made this prediction because I worked out the energy needed in each bond and then how much energy is needed in the balanced equations I drew up for each fuel. Here are the bond energies: C-H 413KJ/mol C-C 347KJ/mol C-O 335KJ/mol O-H 464KJ/mol O-O 498KJ/mol C-O 805KJ/mol Here are the balanced equations: Methanol: CH3O-H + O2 ----- Co2 + H2o Ethanol: C2H5O-H + O2 ----- Co2 + H2o Propanol: C3H7O-H + O2 ----- Co2 + H2o Butanol: C4H9O-H + O2 ----- Co2 + H2o Pentanol: C5H11O-H + O2 ----- Co2 + H2o Once I had the bond energies I could work out how...
