What is Cr2O3 in chemistry?
Cr 2 O 3 is an inorganic compound with chemical name Chromic oxide. It is also called Dichromium trioxide, or Chromium (3+) oxide, or Chromium (III) oxide. It naturally occurs in a mineral eskolaite, which is mostly found in chromium-rich skarns, tremolite, chlorite veins, and meta quartzites.
Where can Cr2O3 be found naturally?
Cr 2O 3 occurs naturally as the mineral eskolaite, which is found in chromium-rich tremolite skarns, metaquartzites, and chlorite veins. Eskolaite is also a rare component of chondrite meteorites. The mineral is named after Finnish geologist Pentti Eskola.
What is the total charge of Cr2O3?
What is the total charge on the Cr 2 O 3 molecule? The two chromium cations hold a charge of +3 each, amounting to a total of +6. Each oxygen ion holds a charge of -2, totalling to -6. The ionic compound is, therefore, neutral.
What is the product when ammonium dichromate is heated with Cr2O3?
(NH4)2Cr2O7 (s) → Cr2O3 (s) + N2 (g) + 4H2O (g). What are the products when ammonium dichromate is heated? With the formula given below, we can see that on heating ammonium dichromate, it decomposes into chromium (III) oxide crystals, nitrogen gas and water vapour. Hence, heating of ammonium dichromate produces N2, Cr2O3 and H2O.
