Chemistry coursework: Burning Fuels Investigation Aim: To find out how much energy is released by each alcohol per gram (g). Research: Alcohols are organic, and each one has its own formula. In this experiment we have used Ethanol, Propanol, Butanol, Pentanol Hexanol, Heptenol, and Octanol. Alcohols react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because heat is given out. Form this reason the reactant energy is higher than that of the product. Ethanol, (C2H5OH) Propanol, (C3H7OH) Butanol, (C4H9OH) Pentanol, (C5H11OH) Hexanol, (C6H13OH) Heptanol, (C7H15OH) Octanol, (C8H17OH) When these alcohols are burnt they show a trend that the fewer the bonds the less energy is released, so the more bonds the more energy is released. Alcohols are good to use in this experiment because they burn easily and all have simular chemical formulas. The equation to work out the energy released per gram is: Mass of...
