What is the charge of Fe in Fe2O3?
The charge of iron in FeO is 2+.Iron has also the charge 3+ in other compounds.
The formula for rust can be represented by Fe2O3 How many moles of Fe are present in 14.2 g of the compound?
14.2g Fe2O3 (1mol Fe2O3/159.7g(2mol Fe/1mol Fe2O3) = 0.178 moles Fe
When the equation Fe2O3 Al ----- Al2O3 Fe is correctly balanced what is the coefficient of Fe?
Fe2O3 + 2Al --> Al2O3 + 2Fe
What mole ratio would you use to determine moles Fe if moles Fe2O3 is known?
X moles Fe2O3 (2 moles Fe/1 mole Fe2O3) 2 : 1
What is the Balanced equation of chemical reaction of iron with water?
Iron + Oxygen= Iron oxideChemical Equation4Fe + 3O2 --> 2Fe2O3No Problem! :)
How do you calculate the Fe content in FeO and Fe2O3?
Mass of Fe=(Mass of Fe2O3)(Mr Fe/ Mr Fe2O3)
What is the charge of Fe in Fe2O3?

When the equation Fe2O3 Al ----- Al2O3 Fe is correctly balanced what is the coefficient of Fe?
Fe2O3 + 2Al --> Al2O3 + 2Fe
What is mean by valency?
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
How do you balance al fe2o3?
2 Al + Fe2O3 ----> Al2O3 + 2 Fe
What mole ratio would you use to determine moles Fe if moles Fe2O3 is known?
X moles Fe2O3 (2 moles Fe/1 mole Fe2O3) 2 : 1
What do you mean by variable valency?
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
What is Fe and Fe2o3 in terms of chemistry?
The first Fe represents an iron atom in the 0 oxidation state while the Fe in Fe2O3 represents iron ion in the +2 oxidation state
Formula for Fe III oxide?
Fe2O3
What equations balances O plus Fe Fe2O3?
The reaction is:4 Fe + 3 O2= 2 Fe2O3
Which metallic element is present in hemoglobin?
the mineral element found in haemoglobin is iron
