Combustion of Alcohols In this investigation, I will be using a spirit burner to burn three different alcohols, to heat up a calorimeter containing water. My task is to investigate the heat produced and the combusting capabilities of each fuel. The fuels I will use are ethanol (C2H5OH), propanol (C3H7OH) and butanol (C4H9OH). The alcohol homologous series has the general formula CnH2n+1OH. I aim to discover how much energy is produced when burning these alcohols. When alcohols are burned, or combust, they react with oxygen in the air to form water and carbon dioxide, e.g.: CH3OH + 1.5O2 CO2 + 2H2O Methanol + Oxygen Carbon Dioxide + Water The energy produced from this is called the heat of combustion. The reaction is also exothermic. This tells us that the reactant energy is higher than the product energy, e.g. using methanol again: Ea = Activation Energy Energy Reactants CH3OH + 1.5O2 Products CO2...
