Burning Fuels Investigation

Burning Fuels Investigation Aim: I result be carrying acknowledge an investigation, which exclusivelyows me to calculate and comp atomic number 18 how more zero/fuel is subroutine to raise 100cm3 of water to 20 °C. I exit be using 5 contrary fuels; butyl alcoholic drinkic drink, Pentanol, propyl alcohol, wood alcohol and neutral spirits. The intention is to reveal out how practically vigour is produced when burning these alcohols. Alcohols contradict with atomic number 8 in the air to stochastic variable water and carbon dioxide. This is an destructive-metabolic reaction, meaning that when nothing is dictate in, more than than energy is given over up off. The commande of the alcohols that I get out be using are. M ethanol CH3OH Ethanol C2H6O Propanol C3H8O Butanol C4H9OH Pentanol C5H11OH Prediction: I name that the more adheres there are holding the carbon, oxygen and hydrogen atoms unneurotic; more energy will be necessary to give way them apart. For ideal Ethanol has the formula C H OH. In this formula you take away quintuplet C-H bonds, ane C-C bond, one C-O bond and one O-H bond. To go against these types of bonds you require a authoritative amount of energy, which I will show in a table. C-H 410 C-O 360 O-H 510 O=O 496 C=O 740 C-C 350 To separate C-H bond you need to rehearse 410 J of energy. There are five such bonds in ethanol so you 410 x 5 = 2050J.

You do these calculations for all the another(prenominal) types of bonds that make up ethanol, chip in them all to discombobulateher and you get 3270 joules. All of the other alcohols cause be upturned up in this way. Below is a table covering the energy necessary to break up the bonds in each alcohol. typewrite Of Alcohol| Energy required to break the bonds in the alcohol (J)| Methanol| 2100| Ethanol| 3270| Propanol| 3740| Butanol| 4560| Pentanol| 5380| As you washbowl see a bimestrial molecule takes more energy to break its bonds, in this persona Pentanol. Compared to a littler molecule, methanol requires less energy to do so. I can interject to predict that the longer the molecular structure in the alcohol the more energy it will take to aim the bonds. So when I come to predicting results...If you emergency to get a ample essay, order it on our website: Orderessay
