Problem 1 (10 pts) Ethanol (C2H60) is produced from agricultural crops and is often added to gasoline. This decreases the amount of crude oil that must be imported and reduces the exhaust emissions. Ethanol combines with O2 in a combustion reaction to produce CO2 and H20. a) Write a balanced chemical equation for the complete combustion of ethanol. b) Determine the mass of Oz (in grams) consumed if 200 g of ethanol are ignited. Show all your work.
