Question

1.) Using C3H18 as gasoline, write the balanced equation for a combustion reaction. 2.) Assuming a fuel tank on a compact car holds 13 gallons of gasoline: a. Calculate the amount, in liters of Oz needed to completely burn the fuel. b. Calculate the total amount, in liters of CO2 produced. C. Calculate the total amount of energy amount.
