Question 4 - Combustion of Octane 0/2 points Cars run on gasoline, where octane (C8H18) is the principle component. This combustion reaction is responsible for generating enough energy to move a vehicle, or do other work. How much co, and H2O (in grams) are produced in the combustion of 1.14 gallons of Octane? (density = 0.703 g/mL) Start with a balanced equation for this combustion reaction! Helpful conversion, there are 4 quarts in a gallon. Beyond that, check out your...
