InterviewSolution

1.	Extra pure `N_2` can be obtained by heatingA. `NH_3 with CuO`B. `NH_4 NO_3`C. `(NH_4)_2 Cr_2 O_7`D. `Ba(N_3)_2`
Answer» Correct Answer - D (a) `NH_3 + Cu O overset (Delta)rarr N_2 (g) + Cu(s) + H_2 O` (b) `NH_4 NO_3 overset (Delta) rarr N_2 O(g) + H_2 O (g)` ( c) `(NH_4)_2 Cr_2 O_7 overset (Delta) rarr N_2 (g) + H_2 O(g) + Cr_2 O_3 (s)` (d) `Ba(N_3)_2 overset (Delta) rarr Ba_3 N_2 + N_2 (g)`.
