The compound that does not proudce nitrogen gas by the thermal decomposition is


A) Ba(N3)2

B) (NH4)2Cr2O7

C) (NH4)2SO4

D) NH4NO2

Answer:

Option C

Explanation:

The thermal decomposition of given compounds is shown below

(NH4)2Cr2O7        N2   +   4H2O  +   Cr2O3

NH4NO2         N   +   2H2O

(NH4)2SO4      2NH3    +    H2SO4

Ba(N3)2       Ba   +  2N2

Thus, only (NH4)2SO4 does not gives Non heating (It gives NH3). While the rest of the given compounds gives N2 on their thermal decomposition.
