Density and melting point are different.
Fe2O3 is Iron III Oxide FeTiO3 is Iron Titanate. They are completely different chemical species.
There can be many compounds containing Iron, Sulfur, and Oxygen : => Ferrous sulfate = FeSO4 => Ferric sulfate = Fe2(SO4)3 => Ferrous Sulfite = FeSO3 => Ferric Sulfite = Fe2(SO3)3 etc.
When iron is burnt (heated) and exposed to air the iron will combine rapidly with oxygen atoms to form FeO molecules (FeO - Iron Oxide - Also known as 'rust' on iron materials)
Since iron oxide is made from TWO elements (Fe, and O), it is a compounds and so you have a MOLECULE, not an atom of iron oxide.
Agreed with anonymous. However, do NOT confuse with Iron(III)oxide; archaically, ferric oxide. Iron is if two different oxidation states indicated by the Roman Numerals (II) & (III). Iron(III)oxide is also known as ferric oxide,, and is the mineral, ironore, used in Blast furnaces to make iron metal. There is also Fe3O4 (Iron(VI)oxide, known as magnetite. This is the 'lodestone' used by ancient navigators to find 'north'. As a length of it always hung in the North/South direction.
Iron oxide is a compound formed by the reaction of iron and oxygen, whereas iron is a pure element. Iron oxide is typically reddish-brown in color due to the presence of oxygen, while iron is silvery-gray. Additionally, iron oxide is less malleable and softer than iron due to its different crystalline structure.
Simple - Look at the formulas involved. FeO and Fe2O3 by reducing them in a blast furnace you remove the oxygen so that the become Fe only. The first FeO is black and is Iron Oxide, the other has two atoms of iron combined with three atoms of Oxygen. Fe2O3 is orange due to the formation of rust, and a common form is Haematite.
A car Rusting is a chemicall change as a the iron in the car is converted into a different substance: 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.
Iron oxide has two main chemical compounds: iron(II) oxide (FeO) and iron(III) oxide (Fe2O3). Both compounds consist of two elements - iron and oxygen.
No, because Iron oxide is not a mixture of Iron and Oxygen. It is a compound in which iron and Oxygen have been chemically combined to create a new substance, which has different chemical and physical properties form either of the two elements which it is made from.
Yes, forming an oxide is a chemical change because it involves a chemical reaction where new substances with different properties are formed. Oxides are compounds made of oxygen and another element, which involves a rearrangement of atoms at a molecular level.
FeO is Iron(II)oxide, archaically , Ferrous oxide. Do NOT confuse with Fe2O3, which is Iron(III)oxide ; Archaically Ferric oxide. The 'iron' atom is in different oxidation states for these two compounds. NB 'Fe' is the chemical symbol for 'Iron', and comes from Latin 'Ferrum' for iron.
Iron can form two different ions, Fe2+ and Fe3+. Because of their different charges these ions will bond differently with anions such as oxide (O2-) As a result we get the compounds FeO and Fe2O3. There is a third oxide which is a combination of the two: Fe3O4
Iron and oxygen react to form iron oxide (rust) that has different properties than the original materials. Another example is hydrogen and oxygen reacting to form water, which has different properties from its constituent elements.

iron and oxygen!
