(B) The combustion reaction for ethene is: $C_2H_4 + 3O_2 \rightarrow 2CO_2 + 2H_2O$According to the stoichiometry,$1 \ L$ of $C_2H_4$ requires $3 \ L$ of $O_2$.Therefore,$10 \ L$ of $C_2H_4$ requires $10 \times 3 = 30 \ L$ of $O_2$.Since air contains $20\%$ oxygen by volume,the volume of air required is:$V_{air} = \frac{V_{O_2}}{0.20} = \frac{30}{0.20} = 150 \ L$.
