Construct a balanced equation for the complete oxidation of glucose.
Use your equation to calculate the number of moles of $\text{CO}_2$ made by one person in one day from $1.20\,\text{kg}$ of glucose.
On the date this question was set, the world population was estimated as $6.82 \times 10^9$. Calculate the total mass of $\text{CO}_2$ generated by this many people in one day. Give your answer in tonnes. [$1\,\text{tonne} = 1.00 \times 10^6\,\text{g}$]
Construct a balanced equation for the complete combustion of octane, $\text{C}_8\text{H}_{18}$.
The density of octane is $0.700\,\text{g cm}^{-3}$. Calculate the amount, in moles, of octane contained in $4.00\,\text{dm}^3$ of octane.
Calculate the mass of $\text{CO}_2$ formed when the fuel-efficient car travels a distance of $100\,\text{km}$.
Calculate how many kilometres the same fuel-efficient car would need to travel to make as much $\text{CO}_2$ as the respiration of $6.82 \times 10^9$ people in one day. Use your answer to a(ii).
Carbon dioxide is one of several gases linked with global warming. When fossil fuels such as octane burn in a car engine, additional atmospheric pollutants are also formed. Give the formula of one atmospheric pollutant that can be produced in a car engine, other than $\text{CO}_2$, and state how this pollutant harms the environment.
