Steam and nitrogen
When heat is applied to ammonium dichromate, it undergoes thermal decomposition to form chromium(III) oxide, nitrogen gas, and water vapor. This reaction is often used as a spectacular demonstration due to the production of a green chromium(III) oxide "volcano" effect along with the release of gas and steam.
(NH4)2 Cr2 O7 --------> N2 + 4H2O + Cr2 O3
The formula for ammonium ion is NH4+ and for dichromate ion is Cr2O7^2-. When these two ions combine, the chemical formula for ammonium dichromate is (NH4)2Cr2O7.
Ammonium hydroxide (NH4OH) yields ammonia (NH3) and water (H2O) when it undergoes decomposition.
The chemical formula (NH4)2Cr2O7 is for ammonium dichromate.

" ammonium dichromate"
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.
The subscript for ammonium in ammonium dichromate is (NH4)2. This means there are two ammonium ions present in the compound.
The dichromate ion is Cr2O7-2. Ammonium dichromate is two ammonium ions and one dichromate ion (to balance charges- ammonium has a +1 charge and dichromate has a -2 charge): (NH4)2Cr2O7. Therefore, ammonium dichromate would contain 7 oxygen atoms.
The formula for ammonium ion is NH4+ and for dichromate ion is Cr2O7^2-. When these two ions combine, the chemical formula for ammonium dichromate is (NH4)2Cr2O7.
When heated, ammonium dichromate undergoes a decomposition reaction, releasing nitrogen gas, water vapor, and chromium(III) oxide as products. This reaction is often used to create dramatic chemical volcano demonstrations due to the visual effect of the escaping gases creating a "fireworks" display.
Ammonium hydroxide (NH4OH) yields ammonia (NH3) and water (H2O) when it undergoes decomposition.
The chemical formula (NH4)2Cr2O7 is for ammonium dichromate.
The molar mass of ammonium dichromate is 252,07 g.
The valency of dichromate ion (Cr₂O₇) in ammonium dichromate (NH₄)₂Cr₂O₇ is 6. This is because the two chromium atoms each have a valency of 6 in the dichromate ion, which is balanced by the two ammonium ions with a valency of 1 each.
