__What are the advantages and disadvantages of using corn to produce ethanol fuel? __ Hamed Zakeri– SCH4U1-02 – November 26th, 2010 Class:C What is Ethanol fuel? Ethanol is a renewable energy source which is most often used as a motor fuel, mainly as a biofuel additive to gasoline. Ethanol is renewable energy source because the energy is generated by using a resource, sunlight, which can't be depleted. Formation of ethanol starts with photosynthesis causing a feedstock (carbon based) such as, sugar cane or corn to grow. Agricultural feedstock is considered renewable because they get energy from the sun by photosynthesis, provided that all minerals required for growth are returned to the soil.

Example of a chemical reaction: Glucose (a simple sugar) is created in the plant by photosynthesis . 6 CO2 + 6 H2O + light → C6H12O6 + 6 O2 During ethanol fermentation, glucose is decomposed into ethanol and carbon dioxide . C6H12O6 → 2 C2H5OH+ 2 CO2 + heat <span style="font-family: 'Times New Roman','serif'; font-size: 12pt;">During the combustion ethanol reacts with Oxygen <span style="font-family: 'Times New Roman','serif'; font-size: 12pt;"> to produce carbon dioxide, water, and heat: <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0cm 0cm 0pt 36pt;">C2H5OH + 3 O2 → 2 CO2 + 3 H2O + heat <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: normal; margin: 0cm 0cm 0pt;">Combustion reaction is doubled because two molecules of ethanol are produced for each glucose molecule, and all three reactions are added together.
