Ethanol as a fuel?

Last term we looked at the advantages and disadvantages of biofuels as opposed to fossil fuels.  There was also a question in your last test about it, so I thought that it was worthy a post as a refresher.

According to the Subject Outline you need to be able to:

Describe the advantages and disadvantages of the use of carbon-based fuels as sources of heat energy, compared with their use as feedstock.

and also related:

Write balanced equations for the complete combustion of fuels in which the only products are carbon dioxide and water.

Describe and write equations for the processes of photosynthesis and aerobic respiration involving glucose.

There is much debate as to whether ethanol is actually ‘carbon-neutral’ or not as compared with fossil fuels such as octane. Have a browse through this website for some further information so that you can make up your mind for yourself…
