Question

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

• A.
  $(N{H}_4{)}_{2}C{r}_2{O}_7$
• B.
  $N{H}_{4}N{O}_2$
• C.
  $(N{H}_4{)}_{2}S{O}_4$
• D.
  $Ba(N_3{)}_2$

Answer 1

The correct option is C

$(N{H}_4{)}_{2}S{O}_4$
$(N{H}_4{)}_{2}S{O}_4\to 2N{H}_3+H_{2}S{O}_4$

On theremal decomposition of $(N{H}_4{)}_{2}S{O}_4,N{H}_3$ is evolved. On thermal decomposition of the othere give compounds, $N_2$ is evolved.

Hence option (3) is the answer
