potassium dichromate
valency of dichromate in potassium dichromate
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.
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.

valency of dichromate in potassium dichromate
Determination of uranium in yellowcake (ammonium diuranate) - some methods: - gravimetry by calcination to U3O8 (only for pure ADU) - volumetry with potassium dichromate - potentiometric titration with potassium dichromate - X-ray spectrometry - gravimetry as oxinate
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.
" ammonium dichromate"
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.
The molar mass of ammonium dichromate is 252,07 g.

It's ammonium dichromate.
3 K2Cr2O7 + 2 (NH4)3PO4 ------------3 (NH4)2Cr2O7 + 2 K3PO4
It is a chemical change because the ammonium dichromate changes color, explodes, and probably creates a gas during the change.
