On heating ammonium dichromate and barium azide separately we get (i) N2 in both cases (ii) N2 with ammonium dichromate and NO with barium azide (iii) N2O with ammonium dichromate and N2 with barium azide (iv) N2O with ammonium dichromate and NO2 with barium azide
Option 1) On heating ammonium dichromate and barium azide separately we get N2 in both cases. (NH4)2Cr2O7→Cr2O3+4H2O+N2. Ba(N3)2→Ba+3N2.
