20 mL of

\mathrm{C}{\mathrm{H}_4}

is burnt with 60 mL of

{\mathrm{O}_2}

. If all measurements are made at the same P and T, what is the volume of unreacted oxygen?

View answer and explanation

Correct option: B

20 mL

Option B (20 mL) is correct because the balanced equation shows that 2 volumes of O2 are required for each volume of CH4, so 40 mL of O2 react, leaving 20 mL unreacted.
