Assume that a car burns octane, $\mathrm{C}_{8} \mathrm{H}_{18}\left(d=0.703 \mathrm{~g} / \mathrm{cm}^{3}\right)$. (a) Write the balanced equation for burning octane in air, forming $\mathrm{CO}_{2}$ and $\mathrm{H}_{2} \mathrm{O}$. (b) If the car has a fuel efficiency of 32 miles per gallon of octane, what volume of $\mathrm{CO}_{2}$ at $25^{\circ} \mathrm{C}$ and $1.0 \mathrm{~atm}$ is generated when the car goes on a 10.-mile trip?

Key Concepts

Fuel Efficiency

Fuel efficiency indicates how effectively a vehicle uses fuel to perform work, typically expressed as miles per gallon. It is crucial for translating the amount of fuel consumed into the corresponding production of combustion products and energy output.

Hydrocarbon Combustion

This concept involves the reaction of a hydrocarbon with oxygen to produce carbon dioxide and water. It is a central topic in chemical thermodynamics and kinetics, where understanding how fuels burn and release energy plays a critical role in energy conversion and engine design.

Balanced Chemical Equations

Writing a balanced chemical equation ensures that mass and atoms are conserved in a chemical reaction. It involves adjusting coefficients to have the same number of each type of atom on both sides of the reaction, which is fundamental for accurate stoichiometric calculations.

Stoichiometry

Stoichiometry is the quantitative study of reactants and products in a chemical reaction. It allows one to determine how much product can be formed from a given amount of reactant by using the proportions derived from the balanced equation.

Air Composition in Combustion

When considering combustion in air, it is important to account for the fact that air is a mixture primarily composed of nitrogen and oxygen. Only the oxygen part reacts with the fuel, while the inert gases like nitrogen are carried along without reacting, affecting the overall reaction dynamics.

Ideal Gas Law

The Ideal Gas Law relates the pressure, volume, temperature, and number of moles of a gas. It is an essential tool in calculating the volume occupied by gases under defined conditions, such as determining the volume of carbon dioxide produced in a reaction.
