How many moles of fe3o4 are needed to prepare 4.05moles of fe2o3?
To find the moles of Fe3O4 needed, we first need to determine the molar ratio between Fe3O4 and Fe2O3. The balanced chemical equation for the conversion will provide this information. If the equation is Fe3O4 -> 2Fe2O3, then the molar ratio is 1:2. Thus, 4.05 moles of Fe2O3 would require 2 * 4.05 = 8.1 moles of Fe3O4.
Write down the formula of two oxides of iron?
FeO, Fe3O4, and Fe2O3
What element does iron react to make iron oxide?
Iron reacts with oxygen to form iron oxide. The chemical formula for iron oxide is Fe2O3 (rust) or Fe3O4.
What is the oxidation number of iron in Fe304?
The oxidation number of iron in Fe3O4 is +2. This is because oxygen is assigned an oxidation number of -2 and the overall charge of the compound is neutral. So, iron must have an oxidation number of +2 to balance out the charges.
What minerals are iron oxides?
Iron oxide is rust. It is formed when the element iron reacts with oxygen in the water or air.
What are the three oxides of iron?
FeO, Fe2O3, Fe3O4 Note: Fe3O4 can be considered as a mixture of FeO and Fe2O3

What is the formula of haematite?
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.
Write down the formula of two oxides of iron?
FeO, Fe3O4, and Fe2O3
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
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
What is the chemical formula for oxygen and iron III?
Fe3O4 (The numbers are subscripts, meaning they are smaller, and go beside the element.)
What is the chemical composition of magnetite?
The iron itself is usually found in the form of magnetite(Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Source:Wiki
What kind of material rust?
Iron or materials containing iron will rust into oxides, either Fe2O3 (light brown) or Fe3O4 (dark brown).
Can you Balance this equation FeOH3 equals Fe2O3 plus H2O?
3Fe + 4(H2O) ---> Fe3O4 + 4(H2) You really should learn this, its not that hard =D
