Gasohol is a mixture of 90% gasoline and 10% ethanol, CH3CH2OH. Ethanol is considered an environmentally friendly fuel additive because it can be made from a renewable source sugarcane. Ethanol burns in air to form CO2 and H20, and, like the combustion of alkanes, this reaction also releases a great deal of energy. Write a balanced equation for the combustion of ethanol.
