`(NH_(4))_(2)Cr_(2)O_(7)` on heating gives a gas which is also given by :

A

heating `NH_(4)NO_(2)`

B

heating `NH_(4)NO_(3)`

C

treating `Mg_(3)N_(2)` with `H_(2)O`

D

treating Na (compound) with `H_(2)O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(NH_(4))_(2)Cr_(2)O_(7) to N_(2)+Cr_(2)O_(3)+4H_(2)O`.
`N_(2)` gas is also given by `NH_(4)NO_(2)`
`NH_(4)NO_(2) to N_(2)+2H_(2)O`.
`NH_(4)NO_(3)` to `N_(2)O+2H_(2)O`.
