Question

On heating ammonium dichromate and barium azide
separately we get
(a) N₂ in both the cases
(b) N₂ with ammonium dichromate and NO with barium
azide
(c) N₂O with ammonium dichromate and N₂ with barium
azide
(d) N₂O with ammonium dichromate and NO₂ with barium
azide

Answer 1

Answer:

(c) N₂O with ammonium dichromate and N₂ with barium

azide✔✔✔✔

Answer 2

N₂ in produced both the cases.

Explanation:

• Ammonium dichromate is the ammonium salt of dichromic acid.

• The formula of this compound is (NH4)2Cr2O7.

• This compound when heated forms chromic oxide, water vapor and nitrogen gas.

• (NH4)2Cr2O7 => Cr2O3 +H2O +N2.

• The second compound is barium azide.

• The chemical formula Ba(N3)2.

• When heated, the compound decomposes Barium metal and nitrogen gas.

• So nitrogen gas is produced in both the cases.
