-1- Jack Mariner Chemistry Coursework 2 Investigating how much energy is produced when burning alcohols. In this investigation I will be burning alcohols to heat up a beaker of water. I will be burning Methanol, Ethanol, Propanol, Butanol and Pentanol. Aim The aim is to find out how much energy is produced when burning these alcohols. 'An alcohol is a series of organic homologous compounds, with the general formula: Cn H n + 1OH' 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. The energy is given out when forming the bonds between the new water and carbon dioxide molecules. The amount of energy produced by such exothermic reactions can be calculated by using the formula: Mass of the substance x rise in temp x SHC (specific heat capacity) The specific heat capacity is the number of joules required...
