Which homologous series of compounds does kerosene belong to?
When kerosene burns in excess air, carbon dioxide and water are formed. Complete the balancing of the equation for the complete combustion of kerosene: $\ldots\ldots\text{C}_{14}\text{H}_{30}(\ell) + \ldots\ldots\text{O}_2(\text{g}) \rightarrow \ldots\ldots\text{CO}_2(\text{g}) + \ldots\ldots\text{H}_2\text{O}(\text{g})$.
Calculate the mass, in tonnes, of $\text{C}_{14}\text{H}_{30}$ burnt on a flight from Beijing to Paris.
Using your equation in (b), Calculate the mass, in tonnes, of $\text{CO}_2$ formed during this flight.
At sea level and at $20^{\circ}\text{C}$, an inflated bicycle tyre contains $710\,\text{cm}^3$ of air at an internal pressure of $6 \times 10^5\,\text{Pa}$. Use the general gas equation $PV = nRT$ to work out the amount, in moles, of air in the tyre at sea level.
If the tyre volume remains unchanged, use your answer to (d) to calculate the pressure inside the tyre at a height of $10000\,\text{m}$.
