INVESTIGATING FUELS DO LARGE MOLECULES TRANSFER MORE ENERGY WHEN THEY BURN? AIM: The aim of this investigation is, to find out which molecules transfer the most energy. PREDICTION: I predict that as the numbers of particles are increased, the energy transferred will also be increased. We will use methanol, ethanol, propanol, butonol and octanol. The word and symbol equations for these reactions are: Methanol: Methanol + oxygen carbon dioxide + water C2H5OH + 3O2 2CO2 +4H20 Ethanol: Ethanol + oxygen carbon dioxide + water C2H5OH + 3O2 2CO2 + 3H20 Propanol: Propanol + oxygen carbon dioxide + water 2C3H7OH + 9O2 6CO2 + 8H2O Butanol: Butanol + oxygen carbon dioxide + water C4H9OH + 6O2 4CO2 + 5H2O Octanol: Octanol + oxygen carbon dioxide + water C8H17OH + 12O2 8CO2 + 9H2O All of these reactions are exothermic reaction. At the start of each reaction, less energy is taken in to break the bonds than is...
