Investigating the alcohols that use the most amount of energy to burn Aim To find out which fuel uses the most amount of energy per mole Background Information We know already how atoms can 'exchange partners' in chemical reactions. This means that the bonds which join atoms to each other must be broken. However, new bonds have to be made as the product forms. Energy is needed to break bonds, it is like pulling 2 strong magnets apart, to pull the 2 magnets apart you require energy, therefore 'breaking bonds' requires energy and because it requires energy this means that it is endothermic. When you make new bonds it is the opposite of the above, it is like 2 magnets moving together because of the attraction, and because making bonds gives out energy it is exothermic. Bond Energy Bond energy is the amount of energy needed to break chemical bonds. We are able to calculate...
