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?

A

`H_(2)O`

B

`CH_(4)`

C

`CO_(2)`

D

`NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_(CO_(2)) = 2ml`
`N_(2)` is left which on reacting with `H_(2)` produces `NH_(3)`
