Chemistry

Carbon fossil fuels are utilized to power our vehicles, makeoil, and even t-shirts. The EPA has determined that a cartransforms a gallon of octane (C8H18) to 33.7 kWh (kilowatt*hours,an expression of energy) in order to power a vehicle.
1. Provide the balanced equation for the complete combustion ofoctane.
2. If a truck is able to drive 360 miles on a tank of octane (22gallons) how much energy is needed to move the vehicle one mile?What mass of CO2 is produced per gallon of octane? (the density ofoctane is 0.703 g/mL)
3. According to the L.A times there are 253 million cars onAmerican roads. Assuming that each car is driven 50 miles each day,five days a week determine the mass and volume of the CO2 producedand mass of octane needed to power them for a year (assuming 20miles per gallon)?
