Question

. A mixture of hydrogen and chlorine occupying 36cubic cm was
exploded. On shaking it with water, 4cubic cm of hydrogen was left
behind. Find the composition of the mixture.

Answer 1

$H_{2}+ Cl_{2} -->2HCl$
4 cm³ of hydrogen is left, so,
ATQ. 2 vol of H and 2 vol of Cl give 2 vol of HCl
therefore, 16 cm³ of H and 16 vol of CL gives 32 cm³ of HCl
 So the composition-
H= (16+4) cm³ = 20 cm³
Cl= 16 cm³

Answer 2

@Brainlyuser

H2 + Cl2 ------> 2HCl

How come are hydrogen and chlorine 2 volumes in your answer?
