In the combustion of alcohols in air, the alcohol reacts with oxygen
molecules, to create carbon dioxide and water. Many bonds are broken
in the process using up energy. At the same time, the atoms reforming
into the new molecules of carbon dioxide and water give out energy. In
the combustion of alcohols, the energy created, when forming bonds
will always be more that what is lost, when breaking bonds, this gives
us excess energy. This energy is given out primarily as heat, but also
as light and sound. As energy is given out it is called an exothermic
reaction. If the opposite were true, it would be an endothermic
reaction. It is never possible to calculate exact energy change by
experimentation due to inaccuracies and energy waste, so we use bond
energy calculations give the exact theoretical energy change.

Bond energy calculations show that the higher the RMM the more energy
will be produced for the same weight of fuel (RMM is the sum of the
atomic......
