Fuels investigation The following investigation is to discover how much energy it takes to break the carbon and hydrogen bonds in Pentane, paraffin Hexane and Heptane. Prediction I predict that the fuel with the most bonds will produce the most amount of energy. The scientific proof that I have behind this is that when bonds are broken and they reform energy is released so if there are more bonds then more energy can be released when they reform. Here are the theoretical values for the energy required to break these bonds. Heptane C7H16+ O2 7 CO2+8 H2O Bonds Broken Energy per bond (KJ Mol-1) Total bond Energy (KJ Mol-1) (C-C) 6 + 347 + 2082 (C-H) 16 + 413 + 6608 (O-O) 11 + 498.3 + 5481.3 Bonds Broken Energy per bond (KJ Mol-1) Total bond Energy (KJ Mol-1) (C=O) 14 - 805 - 11270 (O-H) 16 - 464 - 7427 Total energy required for bond breaking (KJ Mol-1) - 18697 Total energy required for bond breaking...
