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

    A) \[Ba{{({{N}_{3}})}_{2}}\]                   

    B) \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\]

    C) \[N{{H}_{4}}N{{O}_{2}}\]      

    D)        \[{{(N{{H}_{4}})}_{2}}S{{O}_{4}}\]

    Correct Answer: D

    Solution :

    [a] \[Ba{{({{N}_{3}})}_{2}}\xrightarrow{\Delta }Ba+3{{N}_{2}}\] [b] \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow{\Delta }C{{r}_{2}}{{O}_{3}}+{{N}_{2}}+4{{H}_{2}}O\] [c] \[N{{H}_{4}}N{{O}_{2}}\xrightarrow{\Delta }{{N}_{2}}+2{{H}_{2}}O\] [d] \[{{(N{{H}_{4}})}_{2}}S{{O}_{4}}\xrightarrow{\Delta }2N{{H}_{3}}+{{H}_{2}}S{{O}_{4}}\] \[N{{H}_{3}}\] is evolved in case of [d].
