Thermal decomposition of ammonium dichromate gives

A

`N_(2), H_(2)O` and `Cr_(2)O_(3)`

B

`N_(2), NH_(3)` and CrO

C

`(NH_(4))_(2)CrO_(4)` and `H_(2)O`

D

`N_(2), H_(2)O` and `CrO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Thermal decomposition of ammonium dichromate `(NH_(4))_(2)Cr_(2)O_(7)` on heating gives `N_(2), Cr_(2)O_(3)` and `H_(2)O` as follows :
`(NH_(4))_(2)Cr_(2)O_(7) overset(Delta)rarr N_(2) + Cr_(2)O_(3) + 4H_(2)O`
