What is the name of crbr2?
Chromium Bromide
What is the oxidation number of Cr in CrBr?
In CrBr (chromium monobromide) Cr would have an oxidation number of +1. This compound is not known perhaps you meant CrBr3, where chromium has an oxidation number of +3
What is the oxidation number for k2cro4?
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
What is the oxidation number of Cr2O72?
In Cr2O72- chromium (Cr) has an oxidation number of 6+ while oxygen has an oxidation number of 2-.
What is the oxidation number of chromium in K2Cr2O7?
+6

Why the oxidation number of Cr2O72- is 6?
It is true for chromium. But O shows 2asthe oxidation number.
Compound name for chromium bromide?
Another chemical name is chromium trichloride or chromic chloride. Chromium(III) chloride is a chemical name as well.
What is the oxidation number of Fe and Cr in FeCr2O7?
The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.
What is the oxidation number of the phosphorus in chromium III phosphate?
The oxidation number of chromium varies from +2 to +6.
What is the chemical formula for chromium II borate?
The formula is CrBr2. This is derived by balancing the electrons from the atoms. Chromium II has a charge of +2 and Bromine has a charge of -1. Therefore in order for this molecule to be electrically balanced, there must be 2 bromine ions to offset the +2 charge of the chromium ion.
What is the oxidation number for NH42CrO4?
The oxidation number of a compound is zero (nitrogen -3, hydrogen +1, chromium +3, oxygen -2).
