Comprehension # 9
A `10ml` mixture of `N_(2)`, a alkane `& O_(2)` undergo combustion in Eudiometry tube. There was contraction of `2ml`, when residual gases are passed are passed through `KOH`. To the remaining mixture comprising of only one gas excess `H_(2)` was added `&` after combustion the gas product is absorbed by water. causing a reduction in volume of `8ml`.
Gas produced after introduction of `H_(2)` in the mixture?
Identify the hydrocarbon.

A

`CH_(4)`

B

`C_(2)H_(6)`

C

`C_(3)H_(8)`

D

`C_(4)H_(10)`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(n)H_(2n+2)+O_(2)rarrCO_(2)+H_(2)O`
`{:(n=7),(CH_(4)):}`

100 ml of mixture of CH_(4)(g), O_(2)(g) "and" CO_(2)(g) was sparked. There was contraction of 70 ml volume when the mixture was passed through aqueous KOH. The composition of initial gas mixture in (ml) will be in order of CH_(4)O_(2),CO_(2) :

A mixture of C_(3)H_(8)(g) & O_(2) having total volume 100ml in an Eudiometry tube is sparked & it is observed that a contraction of 45ml us observed what can be the composition of reacting mixture.

A mixture pf H_(2) , N_(2) and O_(2) occupying 100 ml underwent reaction so as to form H_(2)O_(2)(l) and N_(2)H_(2)(g) as the only products , causing the volume to contract by 60 ml. The remaining mixture was passed through pyrogallol causing a contraction of 10 ml . to the remaining mixture excess H_(2) was added and the above reaction was repeaped , causing a reduction in volume of 10 ml .(No other products are formed) What is the volume percent of H_(2) in the initial mixture?
