Sample questions
-
1.What volume of air (containing 20% O₂ by volume) will be required to burn completely 10 cm³ each of methane and acetylene? $$\begin{array}{l}\mathrm{CH}_4 + 2\mathrm{O}_2 \rightarrow \mathrm{CO}_2 + 2\mathrm{H}_2\mathrm{O} \\ 2\mathrm{C}_2\mathrm{H}_2 + 5\mathrm{O}_2 \rightarrow 4\mathrm{CO}_2 + 2\mathrm{H}_2\mathrm{O}\end{array}$$
-
2.(ii) The vapour density of a gas is 8. What would be the volume occupied by $24.0\,\mathrm{g}$ of the gas at STP?
-
