The oxidation number of chromium (Cr) in dichromate ion (Cr2O7^2-) is +6. This is because oxygen (O) is typically assigned an oxidation number of -2, and the overall charge of the ion is -2, so the two chromium atoms must have a total oxidation number of +12 to balance the charge.

What is the oxidation number of O of Cr2O7?
The oxidation number of oxygen in Cr2O7 is -2. Since there are seven oxygen atoms in the dichromate ion (Cr2O7), and the overall charge of the ion is -2, each oxygen atom is assigned an oxidation number of -2.
What is the oxidation number for Cr in Cr2O7-2?
The oxidation number for Cr in Cr2O7^2- is +6. Each oxygen atom has an oxidation number of -2, so the sum of the oxidation numbers in the compound must equal the charge of -2 for the entire ion.

What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +6. Each oxygen atom has an oxidation number of -2, and the overall charge of the Cr2O7 ion is -2, so the total oxidation number for the two chromium atoms must equal +12 to balance it out. Therefore, each chromium atom has an oxidation number of +6.
What is the oxidation number for 0 in k2cr207?
In K2Cr2O7, the oxidation number of oxygen is typically -2. Since there are two oxygen atoms in the dichromate ion (Cr2O7)^2-, the total oxidation number contribution from oxygen is -14. To balance this, the oxidation number of Cr is +6. Therefore, the oxidation number of O in this compound is -2.
What is the oxidation number of Cr in Cr2O72 is?
The oxidation number of Cr in Cr2O7^2- is +6. This is because the overall charge of the dichromate ion is 2-, and each oxygen atom has an oxidation number of -2. By setting up and solving an equation representing the total charge of the ion, we can determine the oxidation number of Cr.
What is the oxidation number of Cr2O72?
The oxidation number of Cr in Cr2O7^2- ion is +6. Each oxygen atom has a -2 charge, and the overall charge of the ion is 2-, so combining the charges gives -2*(-7) = -14. Since the overall charge is 2-, the oxidation number of Cr must be +6 to balance the charges.
What is the oxidation number of Cr in HCr2o7?
The oxidation number of Cr in HCr2O7 is +6. This is because each oxygen atom has an oxidation number of -2, and there are four oxygen atoms in the dichromate ion (Cr2O7)^2-. The overall charge of the ion is -2, which means the two chromium atoms must have a total oxidation number of +12 to balance the charge, resulting in an individual oxidation number of +6 for each chromium atom.
What are the oxidation numbers of magnesium in magnesium dichromate?
The oxidation number of magnesium in magnesium dichromate (MgCr2O7) is +2. In dichromate ion (Cr2O7^2-), each oxygen atom has an oxidation number of -2. Since the overall charge of the dichromate ion is -2, each chromium atom must have an oxidation number of +6, and each magnesium atom must have an oxidation number of +2 to balance the charges.
What element is reduced in this reaction cr2o7 3hno2 5h-2cr3 3no3 4h2o?
In this reaction, chromium (Cr) is being reduced from a +6 oxidation state in Cr2O7 to a +3 oxidation state in 2Cr3+.
