How many moles of fe3o4 are needed to prepare 4.05moles of fe2o3?
Fe3O4 is not a pure compound...it is a mixture of FeO and Fe2O3 Assuming 100% yield in converting to all Fe2O3 4.05 mole x 2/3 = 2.7 mole
Write down the formula of two oxides of iron?
FeO, Fe3O4, and Fe2O3
You heat 3.970 g of a mixture of Fe3O4 and FeO to form 4.195 g Fe2O3 The mass of oxygen reacted is?
0.225
What is the oxidation number of iron in Fe304?
Fe3O4 is FeO.Fe2O3 and it is always -2 for Oxygen and +2 for iron (in FeO) and +3 for iron (Fe2O3)
Is iron oxide a element compound or a mixture?

Hematite is an oxide of iron in its "raw" or "natural" form. It's a mineral, and it's iron(III) oxide. Its formula is Fe2O3.Hematite is Fe2O3.
Formula for iron II oxide?
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
FeO and FE3O4 react to form 5.779g of Fe2O3 What is the percent by mass of FeO if Feo and Fe3O4 is 5.280g.?
just apply poac on both the sides and get the solution
What is the symbol equation for iron oxide plus calcium?
There are at least three different iron oxides, with formulas FeO, Fe2O3, and Fe3O4. The equations are: FeO + Ca = CaO + Fe Fe2O3 + 3Ca = 3CaO + 2Fe Fe3O4 + 4Ca = 4 CaO + 3Fe

These compounds are iron oxides as FeO, Fe2O3, Fe3O4.Rust.
What is the chemical formula for oxygen and iron III?
Fe3O4 (The numbers are subscripts, meaning they are smaller, and go beside the element.)
You heat 3.970 g of a mixture of Fe3O4 and FeO to form 4.195 g Fe2O3 The mass of oxygen reacted is?
0.225
How do you balance the folowing equation Fe H20 --Fe3O4 H2?
Fe3O4 is the mineral magnetite, with aproper chemical name of Fe(II, III) oxide. it exhibits ferrimagnetism. It has iron atoms as FeII and FeIII. An old way of writing it was FeO.Fe2O3 The balanced equation for production from the elements is :- 3Fe + 2O2 -> Fe3O4 Commercially it is made by for example redung Fe2O3 with CO 3Fe2O3 + CO = 2Fe3O4 +CO2
