`200ml` of a gaseous mixture containing `CO,CO_(2)` and `N_(2)` on complete combusion in just sufficient amount of `O_(2)` showed contration of `40ml`. When the resulting gases were passed through `KOH` solution it reduces by `50%` then calculate the volume ratio of `V_(co_(2)): V_(CO): V_(N_(2))` in original mixture .

100 ml of gaseous mixture containing CO, CO_(2) and O_(2) was sparked there was contraction of 80mL volume when the nixturc was passed through aqueous caustic potash KOH. The omposition of initial gaseous mixture will be respectively:

10ml of mixture containing CO and N_(2) required 7 ml of oxygen to form CO_(2) and NO respectively on combution. Find the volume of N_(2) in the mixture.

A mixture of 100ml of CO,CO_(2) and O_(2) was sparked. When the resulting gaseous mixture was passed through KOH solution, contraction in volume was found to be 80ml , the composition of initial mixture may be (in the same order)

12 mol gaseous mixture of an alkane and an alkene (containing same number of carbon atoms) require exactly 285 ml of air (containing 20% v/v O_(2) and rest N_(2) ) for complete combustion at 200K . After combustion when gaseous mixture is passes through KOH solution it shows volume contraction of 36 ml. Mole fraction of CO_(2) in final gaseous sample:

A gaseous mixture contains CO_(2) (g) and N_(2)O (g) in a 2 : 5 ratio by mass. The ratio of the number of molecules of CO_(2) (g) and N_(2)O is
