What would be the product when ethene is oxidised with cold dil. KMnO4 solution -
For an ideal solution of two components 
and B, which of the following is true?
i.e. as the solubility increases, value of Henry's law constant decreases. Since 
is most soluble in water among the given set of gases. Therefore 
has the lowest value of Henry's law constant.

of hydrogen measured at STP dissolves in 
of water. If water at 
is exposed to a gaseous mixture having a total pressure of 
of 
(excluding the vapour pressure of water) and containing 
hydrogen by volumne, then the volume of hydrogen measured at STP that will dissolve in 1 L of water is
