chemistry coursework FuelsPlanning========Aim---In this investigation I go forth contract to find out which of the alcohol open fires methanol, ethanol, propanol and butanol, is the scoop out. Thebest one forget be the one which creates the most energy whilstburning.Introduction and prediction---------------------------A fuel is a substance burned for heat or power. The best type of fuelis one that can be transported safely without the manage of itcatching on fire, gives out a lot of heat for a certain mass, does notcost very much, lights quickly, burns slowly, is safe to social occasion and doesnot give off any form of polluting gases.When burning alcohols, as I am going to do in this investigation, thereaction is exoergic as heat is given out. Breaking the bonds of theoriginal alcohol by burning acquires energy-it is endothermic, makingthe bonds of the new products of burning the alcohol ie deoxycytidine monophosphate dioxideand water gives out energy-it is exothermic.I predict that Butanol will require the most energy as it has the mostbonds holding the carbon, oxygen and enthalpy atoms together. Propanolwill require the second largest amount of energy, fermentation alcohol the one-thirdand Methanol the least amount of energy to break these bonds.Methanol CH3OHEthanol C2H5OHPropanol C3H7OHButanol C4H9OHPentanol C5H10OHTherefore I predict that Methanol will be the best fuel, followed byEthanol, then Propanol and the worst fuel will be Buta...
