Chemistry Coursework Objective My aim is to investigate and compare the amount of energy released during the combustion of alcohols with practical and theoretical combustions. Combustion (burning) is the reaction of substance with oxygen. I aimed to use four different alcohols, these being: * Ethanol * Butanol * Proponol * Methanol Method I set up the apparatus as the diagram shows: To start the experiment I weighed the empty burner using electronic scales, and then added 75ml of the alcohol I was using, and then weighed it again. I then calculated the mass of alcohol in the burner. I then took the temperature of the water, and then lit the burner. I decided to keep the experiment running each time until the water had risen 200c. when this had happened I blew out the burner, and re-weighed it, so that I could calculate how much alcohol had been burned. At this point I used the formula: Energy = Mass of Water x...
