ions valency is 3 and oxygen valency is 2 so how can so it should be Fe2O3 than how it is Fe3O4

Fe3O4 is a molecule in which Fe shows both of its oxidation states
iron has two oxidation states +2 and +3
so Fe3O4 is basically a combination of
FeO and Fe2O3
can be written as Fe0. Fe2O3
you see in FeO ( fe shows +2 valency)
in Fe2O3 ( fe shows +3 valency)
iron has two oxidation states +2 and +3
so Fe3O4 is basically a combination of
FeO and Fe2O3
can be written as Fe0. Fe2O3
you see in FeO ( fe shows +2 valency)
in Fe2O3 ( fe shows +3 valency)

ya
take out the chapter 'chemical reactions and equations "
and check out "decomposition reaction"
a reaction is given that Fe2(SO4)3 when heated , gets converted to FeO, and So3 , So2
I got it
thanks
basically, Fe3O4 does not exist, it is just a combination of both Fe0 and Fe2O3.
FeO : Ferrous Oxide ( Ore is called wustile).....
Fe2O3 : Ferric Oxide ( Ore is called Haematite)......
Fe3O4 : Ferroso-ferric Oxide (Ore is called Magnetite, in this ore , we find both FeO and Fe2O3, so we call it Fe3O4)
Fe2O3 : Ferric Oxide ( Ore is called Haematite)......
Fe3O4 : Ferroso-ferric Oxide (Ore is called Magnetite, in this ore , we find both FeO and Fe2O3, so we call it Fe3O4)
oh okay all the best brother
why we write bromine with the subscript 2?

Iron has two valencies +2 and +3 depending upon the no. of electrons it donates . So it can react with same element in different ratio to form two different compounds. also consider C and O ---- CO and CO2 .. and N and O ...
