Chapter 0, Problem C1.24

(choose chapter or problem)

One of the components of gasoline is octane, \(\mathrm{C}_{8} \mathrm{H}_{18}\), which has a density of 0.803 g/mL. The combustion of 1 mole of octane provides 5510 kJ. A hybrid car has a fuel tank with a capacity of 11.9 gal and a gas mileage of 45 mi/gal. (7.1, 7.3, 7.8, 11.2)

a. Write the balanced chemical equation for the combustion of octane.

b. Is the combustion of octane endothermic or exothermic?

c. How many moles of octane are in one tank of fuel, assuming it is all octane?

d. If the total mileage of this hybrid car for one year is 24 500 mi, how many kilograms of carbon dioxide would be produced from the combustion of the fuel, assuming it is all octane?
