Question

Ammonium dichromate on heating gives?

Answer 1

Ammonium dichromate:

• Ammonium dichromate is an inorganic compound.
• The chemical formula of ammonium dichromate is ${\left({\mathrm{NH}}_4\right)}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$.
• It is an orange-coloured compound.

The reaction of heating of ammonium dichromate:

• Ammonium dichromate $\left({\left({\mathrm{NH}}_4\right)}_2{\mathrm{Cr}}_2{\mathrm{O}}_7\right)$ on heating yields chromic oxide $\left({\mathrm{Cr}}_2{\mathrm{O}}_3\right)$ which is green in colour and water along with the liberation of nitrogen gas.
• The chemical reaction can be depicted as:

${\left({\mathrm{NH}}_4\right)}_2{\mathrm{Cr}}_2{\mathrm{O}}_7\left(\mathrm{s}\right)\stackrel{∆}{\to }{\mathrm{Cr}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+4{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right)$
