Question

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

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

Answer 1

The correct option is A $(N{H}_4{)}_{2}S{O}_4$

$\left(N{H}_4{)}_{2}S{O}_4\stackrel{△}{\to }2N{H}_3\right(g)+H_{2}S{O}_4$

$Ba(N_3{)}_2\stackrel{△}{\to }Ba+3N_2(g)$

$\left(N{H}_4{)}_{2}C{r}_2{O}_7\stackrel{△}{\to }{N}_2\right(g)+C{r}_2{O}_3+4H_{2}O$

$N{H}_{4}N{O}_2\stackrel{△}{\to }{N}_2\left(g\right)+2H_{2}O$
