20 ~mL of methane is completely burnt using 50 ~mL of oxygen. The volume of the gas left after cooling to room temperature is

Options

  1. A40 ~mL
  2. B60 ~mL
  3. C30 ~mL
  4. D80 ~mL

Correct answer

C. 30 ~mL

Step-by-step solution

Volume of gas left after cooling =10 mLO ₂+20 ~mL CO ₂=30 ~mL H ₂ O ( g ) will be condense to H ₂ O ( l ) after cooling.
