Extra pure N_2 can be obtained by heating

Extra pure

\mathrm{N}_2

can be obtained by heating

Options

A $\mathrm{NH}_3$ with $\mathrm{CuO}$
B $\mathrm{NH}_4 \mathrm{NO}_4$
C $\left(\mathrm{NH}_4\right)_2 \mathrm{Cr}_2 \mathrm{O}_7$
D $\mathrm{Ba}\left(\mathrm{N}_3\right)_2$

Correct answer

D. $\mathrm{Ba}\left(\mathrm{N}_3\right)_2$

Step-by-step solution

\mathrm{Ba}\left(\mathrm{N}_3\right)_2 \stackrel{\text{ Heat }}{\longrightarrow} \mathrm{Ba}(\mathrm{s})+3 \mathrm{ N}_2(\mathrm{ g})

Azide salt of barium can be obtained in purest form as well as the decomposition product contain solid
