Question

Which of the following compounds on thermal decomposition gives $N_2$ gas?

• A. $N{H}_{4}N{O}_2$
• B. $Ba(N_3{)}_2$
• C. $Na{N}_3$
• D. All of the above.

Answer 1

The correct option is D All of the above.

The decomposition reactions are given below:
$N{H}_{4}N{O}_2\left(aq\right)\to N_2\left(g\right)\uparrow +2H_{2}O\left(l\right)$
$Ba\left(N_3{)}_2\right(s\left)\stackrel{\Delta }{\to }Ba\right(s)+3N_2(g)\uparrow$
$2Na{N}_3\left(s\right)\stackrel{\Delta }{\to }2Na\left(s\right)+3N_2\left(g\right)\uparrow$
$\therefore$ option (d) is correct.
