Sodium nitrate decomposes above `800^(@)C` to give

A

`N_(2)`

B

`O_(2)`

C

`NO_(2)`

D

`Na_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
Sodium nitrate on decmposition upto `500^(@)C` to give `NaNO_(2)` and oxygen
`2NaNO_(3) overset(Delta)to2NaNO_(2) + O_(2) uarr`
While at higher temperature (i.e. above to `800^(@)C`) this `NaNO_(3)` is decomposed into `Na_(2)O,N_2 and O_(2)`
`2NaNO_(3) overset(800^(@)C)to Na_(2)O + 3/2 O_(2) uarr +N_(2) uarr`
