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 FeCr2O7?
The oxidation number of Fe in FeCr2O7 is +2. This is because the overall charge of the compound is zero and there are two chromium atoms with an oxidation number of +6 each, leading to a total negative charge of -12. Therefore, the Fe atom must have an oxidation number of +2 to balance the charges.
The oxidation number of Fe in Fe2S3 is?
The oxidation number of Fe in Fe2S3 is +3. This can be determined by setting up an equation where the total oxidation number of the compound is equal to zero, and solving for the unknown oxidation number of Fe.
What is the oxidation number for Fe in FeBr2?
The oxidation number of Fe in FeBr2 is +2 because each Br has an oxidation number of -1 and the overall charge of the compound is zero.
What is the Oxidation number of Fe3?
The oxidation number of Fe in Fe3+ is +3. This is because Fe is a transition metal and can exhibit multiple oxidation states. In this case, Fe has lost three electrons to form a 3+ charge.
What is the oxidation number of the Fe in FeO?
The oxidation number of Fe in FeO (iron oxide) is +2. Oxygen is typically assigned an oxidation number of -2, so since FeO is a neutral compound, the oxidation number of Fe must be +2 to balance out the charge of the oxygen.
What is the oxidation number of FeCr2O7?
The oxidation number of Fe in FeCr2O7 is +2. This is because the overall charge of the compound is zero and there are two chromium atoms with an oxidation number of +6 each, leading to a total negative charge of -12. Therefore, the Fe atom must have an oxidation number of +2 to balance the charges.
If 309 moles of FeCr2O7 react how many moles of O2 will be consumed?
To determine how many moles of O2 are consumed when 309 moles of FeCr2O7 react, we first need the balanced chemical equation for the reaction. Assuming FeCr2O7 decomposes to yield Fe, Cr, and O2, a typical reaction could produce 3 moles of O2 for every mole of FeCr2O7. If this is the case, 309 moles of FeCr2O7 would consume 3 × 309 = 927 moles of O2.
The oxidation number of Fe in Fe2S3 is?

What is the oxidation number of the Fe in FeO?
The oxidation number of Fe in FeO (iron oxide) is +2. Oxygen is typically assigned an oxidation number of -2, so since FeO is a neutral compound, the oxidation number of Fe must be +2 to balance out the charge of the oxygen.
What is the Oxidation number of Fe2s3?
The oxidation number of Fe in Fe2S3 is +3. This is because the overall charge of the Fe2S3 compound is 0, and since there are 2 Fe atoms each with an unknown oxidation number "x" and 3 S atoms each with an oxidation number of -2, the sum of the oxidation numbers must equal 0. Solving for x gives +3 for the oxidation number of Fe.
What is the oxidation number to Fe2O3?
The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.
Oxidation numbers of Fe?
The oxidation numbers of iron (Fe) can vary depending on the compound it is part of. For example, in FeCl3, iron has an oxidation number of +3, while in FeCl2, its oxidation number is +2. In elemental form, such as in Fe metal, the oxidation number is 0.
What is the oxidation number of fe 2?
The oxidation number of Fe in Fe2 is +2. Iron typically forms ions with a +2 oxidation state.
Which of these metals has the hardest oxidation Cu Al Fe or Cr?
Chromium (Cr) has the hardest oxidation state among the listed metals. It commonly exhibits an oxidation state of +6 in compounds due to its high electronegativity and tendency to lose electrons.
What is the oxidation number of Fe in K3Fe CN6?
a)3 b)2 c)1 d)4 Fe is the transitional metal K3[Fe(CN)6] , we know that Potassium, K, has an oxidation number of +1 The oxidation number of CN= -1, so 6*CN has an oxidation number of -6 so therefore Fe - 6 = -3 Fe = -3 + 6 = +3 The oxidation number of Fe is +3. so A
