Question

On heating ammonium dichromate and barium azide separately we get:


A
N2 in both cases
loader
B
N2 with ammonium dichromate and NO with barium azide
loader
C
N2O with ammonium dichromate and N2 with barium azide
loader
D
N2O with ammonium dichromate and NO2 with barium azide
loader

Solution

The correct option is A $$N_{2}$$ in both cases

On heating ammonium dichromate and barium azide separately we get $$N_2$$ in both cases.

$$(NH_4)_2Cr_2O_7 \rightarrow Cr_2O_3 + 4H_2O +N_2$$.

$$Ba(N_3)_2 \rightarrow Ba + 3N_2$$.

Hence option A is correct.
