Fe2O3 is oxide of iron called hematite, color is red. Note that rust is chemically the same as hematite. It conatins Fe-Ferrum, ie, Greek for Iron. O is oxygen, as in simple English. Fe2O3 is the most commonly occurring iron ore, viz., hematite, and is used for the production of Pig Iron in a Blast furnace.
There are several other oxides of Iron like :
FeO : Wustite, Fe3O4: Magnetitre-black in color. Actually, Magnetite is considered to be a combination of Hematite and Wustite: Fe2O3 . FeO = Fe3O4
Pure Fe2O3 is used as magentic material, like Ferrite, used in electronics. However, it is not alone but in combinatio of of other ferromagnetic material.

What else can I help you with?
How many molecules of iron are there in iron oxide?
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
Fe2O3 is named iron 3 oxide because it contains?
It is named 'iron three oxide' , not because it combines with three oxygens, but because of the number of electrons on the iron atom involved in combining with another atom. Iron has six (6) electrons in its outer electron shell. Of these six , three are are ionised to form the ion Fe^(3+) ; that is it has 'lost' three electrons. It is this ion and its 'lost' three electrons that form the combination to other atoms. NOT the number of Oxygen atoms.
Why is fo2o3 named iron oxide?
First of all to correct your formula. It is ' Fe2O3'. Note the use of Capital Letters and the position of the numbers. Secondly ' Fe' is the Latin initials for the word 'iron', which is 'Ferrum'. Hence Fe2O3 is Iron Oxide. Iron exhibits different oxidation states. For given compound of iron, it is correctly named as 'Iron (III) Oxide '. ' Said as 'Iron three oxide '. In everyday terms , this is 'RUST'. Or mined as 'iron ore'. Archaically it would be named as 'Ferric Oxide'. Note the root word 'ferric/ferrum' for iron. Also note the use of Roman Numerals (III) for '3' , to indicate oxidation state. Iron also exhibits different oxidation states. This makes for the other iron compound ' FeO ' , which is Iron (II) Oxide, and is archaically named as Ferrous Oxide. It is in oxidation state (II) '2'. This is much less common and is green in colour.
How many iron atoms are in one molecule of iron oxide?
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
When an iron nail rusts what does its mass do?
The iron is reacting with other substances in the surrounding enviornment. This typically changes the iron atoms into molecules of iron oxide. Because the rust contains more atoms, the iron and now oxygen atoms, the mass of the nail increases.
Fe2o3 is named iron oxide because it contains?
Fe2O3 is named iron oxide because it is a compound composed of two iron (Fe) atoms and three oxygen (O) atoms. This combination forms a mineral with a red-brown color, giving it the common name "iron oxide."
Fe2O3 is named iron oxide because it contains which type of iron ions?
Fe2O3 is named iron oxide because it contains Fe+ ions.
If metal rusts is it the same metal?
Rust is the oxide of Iron. So iron has chemically combined with oxygen, to form a different compounds named iron oxide . This oxide contains in combined form iron and oxygen.
Why is Fe2O3 named iron III oxide?
Iron exists in two oxidation states: Fe2+ and Fe3+. To distinguish between these two oxidation states and to specify which kind of ion will form on dissociation, they are named as Iron II and Iron III. Now, Fe2O3 contains the Fe3+ ion. That is why, it is called iron III oxide.
What metal is in iron oxide?
Iron oxide contains iron as the metal component.
How many molecules of iron are there in iron oxide?
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.

What.........Fe2O3 is named iron (III) oxide because it contains . a. three unpaired electrons c. three iron atoms b. Fe3 plus ions d. O3 plus ions?
b. Fe3 plus ions
What is in each molecule of iron oxide contains atom of iron?
yes
What elements does the compound iron oxide have?
Iron oxide contains iron (Fe) and oxygen (O) elements. The most common forms of iron oxide are magnetite (Fe3O4) and hematite (Fe2O3).
What is iron oxide made up of?
Iron oxide is made up of iron and oxygen combined together. There are three types of iron oxide viz., Iron(II) oxide (FeO) occasionally referred to as 'greenstone' , because it is slightly green in colour. Iron(III) oxide (Fe2O3) commerically referred to as iron ore. It is the most common and stable of the oxides of iron. Iron(IV)Oxide (Fe3O4) known as magnetite. Because a rod or bar of it will orientate towards the north pole. Historically it was named 'lodestone'.
