A mixture of $10 mL$ $H X_{2}$ , $10 mL$ $CH X_{4}$ and $40 mL$ $O X_{2}$ is exploded in a eudiometer and the products are cooled to room temperature (water liquid). Which statements are correct?

Answer: A, B, C, D

2 H X_{2} + O X_{2} 2 H X_{2} O (l)

uses

5 mL

O X_{2}

;

CH X_{4} + 2 O X_{2} CO X_{2} + 2 H X_{2} O (l)

uses

20 mL

O X_{2}

and gives

10 mL

CO X_{2}

O X_{2}

used

= 25

(A); left

= 15

. Residual

= 15 + 10 = 25 mL

(B). KOH absorbs the

10 mL

CO X_{2}

(C). Contraction

= 60 - 25 = 35 mL

(D). All correct.
