The oxidation state of chromium (Cr) in Ag2Cr2O7 is +6. This is because the total charge of the compound is zero, and the oxidation states of silver (Ag) and oxygen (O) are fixed. By assigning an oxidation state of +6 to oxygen, we can determine that chromium is in the +6 oxidation state.

What is the change in the oxidation number of Cr?
The change in oxidation number of Cr depends on the specific reaction or compound involved. For example, in the reaction from Cr(III) to Cr(VI), the oxidation number of Cr changes from +3 to +6, indicating an increase in oxidation state.

The oxidation number for Cr in Cr2O7^2- is +6.
What is the oxidation number of Cr in CaCrO4?
+2 for Ca, +6 for Cr, -2 for each O
What is the oxidation number of Cr2O3?
+3 for Cr and -2 for O
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
Is the normal oxidation state of chromium cr ii?
No, the normal oxidation state of chromium is Cr(III). However, it can also exist in other oxidation states such as Cr(0), Cr(II), Cr(IV), and Cr(VI) depending on the compound it is part of and the reaction conditions.

What is the oxidation number for Cr in MgCrO4?
The oxidation number of Cr in MgCrO4 is +6. This is because oxygen is typically assigned an oxidation number of -2, and the overall charge of the compound is 0, so the oxidation number of magnesium (+2) and oxygen (-2) must be balanced by the oxidation number of Cr (+6).
What is the oxidation number of element Cr?
As with any other element, the oxidation number of Cr depends on whether and how it is chemically bonded. The oxidation number of pure elements is arbitrarily defined to be 0. In compounds, Cr has oxidation numbers of +2, +3, and +6, depending on the compound.
What is the oxidation number of CrO42?
The oxidation number of chromium (Cr) in CrO4^2- is +6. Since each oxygen atom has an oxidation number of -2, and the overall charge of the polyatomic ion is -2, the oxidation number of chromium can be determined by solving the equation: (oxidation number of Cr) + 4(-2) = -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 states of Na2Cr2O7?
In Na2Cr2O7, sodium (Na) has an oxidation state of +1, and oxygen (O) typically has an oxidation state of -2. Given that the overall compound is neutral, the oxidation state of chromium (Cr) in this case is +6.
How many bonds can Cr form?
Chromium (Cr) can form different numbers of bonds depending on its oxidation state. In its common states, Cr can form up to 6 bonds in the +3 oxidation state and up to 8 bonds in the +6 oxidation state.
