Iron(3+) sulfide is a member of the class of iron(3+) sulfides that has formula Fe2S3. A black powder, it decomposes at room temperature to give iron(2+) chloride, hydrogen sulfide, and sulfur.


What is the cation and anion of NH4F?

Answer and Explanation: The given compound has a chemical formula of NH4F N H 4 F . In an ionic compound, the cation is written first before the anion, therefore, we expect that the cation will be NH+4 N H 4 + and the anion is F− . The F atom is an example of a halogen that usually exists as an anion with a -1 charge.


Is CrN chromium II?

Chromium nitride is a chemical compound of chromium and nitrogen with the formula CrN. Chromium forms a second interstitial nitride, dichromium nitride, Cr2N.


How many electrons does Cr2O7 2 have?

Total valance electrons pairs = σ bonds + π bonds + lone pairs at valence shells. Total electron pairs are determined by dividing the number total valence electrons by two. For, Cr2O72- there are 56 valence electrons, so total pairs of electrons are 28.


What is the oxidation number of Cr2O7?

See also  Why did Ron have a seizure?

The sum of the oxidation numbers in Cr2O72-, a polyatomic ion, is -2, the charge of the ion. There are seven oxygen atoms, so the total charge is − 2⋅7 = − 14. So, a chromium atom here has an oxidation number of + 6.


Why is Cr2O7 orange?

32. The Orange colour of Cr2O72– ion changes to yellow when treated with an. alkali because of the formation of chromate ion CrO42- ion, which is yellow in colour.


Is Mn 2 Colourless?

Answer: The complexes with d5 configuration of Mn are centrosymmetric (having center of symmetry) and therefore d-d transition in these complexes is not allowed. The colour of the complex which is due to d-d transition is thus not present in Mn. Hence, they are almost colourless.


What color is fecl3?

Ferric chloride is an orange to brown-black solid. It is slightly soluble in water. It is noncombustible.


What’s the hybridization of CO3 2?
