What is the Valency of iron in Fe3O4?
Why is the chemical formula of iron oxide Fe3O4 when the valency of iron is 2,3 and that of oxygen is 2.
What mineral is Fe2O3?
hematite Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).
Why is Fe3O4 magnetic?
The magnetic interaction among iron ions at octahedral and tetrahedral sites is antiferromagnetic and that among octahedral ions is ferromagnetic; overall a ferrimagnetic arrangement of Fe3O4. Therefore, the net magnetic moment in Fe3O4 is due to Fe2+ ions (4 μB).
What percentage of iron is contained in an iron ore that is 80.00% by mass fe2o3?
1 Answer. 69.9% to three significant figures.
Is Fe3O4 mixed oxide?
Thus, Fe2O3 is a simple oxide where Fe is only + 3 in the oxidation state thus Fe3O4 is a mixed oxide where Fe is present in both + 2 and + 3 oxidation states.
What is the valence of Fe in Fe2O3?
3 The valency of iron in Fe2O3 is 3. The formula of iron (III) oxide is given as Fe2O3. The formula is derived by taking the valency of the compound. Generally, oxygen (O) has a valency of 2 whereas Iron (Fe) has a valency of 3.
What is the name of the compound Fe2O3?
Iron(III) oxide Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO) the rarer form, and iron(II,III) oxide (Fe3O4) which naturally as magnetite.
Which of the following is haematite a Fe3O4 B Fe2O3?
Iron ore consists primarily of hematite (Fe2O3) and magnetite (Fe3O4) in proportions which vary appreciably among ore bodies, as well as variously hydrated hematites, siderite (FeCO3), and pyrite (FeS2).
What is the magnetic moment of Fe3O4?
The trivalent Fe3+ ion is in the state with a spin S = 5/2 and zero orbital moment. The bivalent Fe2+ ion has a spin of 2, and its contribution comes to ~4μB, unless one considers a certain possible contribu tion from orbital moment (2). The measured value of the magnetic moment for magnetite is 4.1μB.
Which is ferromagnetic substance Fe3O4?
The magnetic interaction among iron ions at octahedral and tetrahedral sites is antiferromagnetic and that among octahedral ions is ferromagnetic; overall a ferrimagnetic arrangement of Fe3O4. Therefore, the net magnetic moment in Fe3O4 is due to Fe2+ ions (4 μB).
How do you find the percent by mass of iron?
Mass percent composition of Fe = mass contribution of Fe/molecular mass of K3Fe(CN)6 x 100% Mass percent composition of Fe = 55.85 g/mol/329.27 g/mol x 100% Mass percent composition of Fe = 0.1696 x 100% Mass percent composition of Fe = 16.96%
Why is Fe3O4 called mixed oxide?
They are ferrous oxides. Thus, Fe2O3 is a simple oxide where Fe is only + 3 in the oxidation state thus Fe3O4 is a mixed oxide where Fe is present in both + 2 and + 3 oxidation states.
What is the valency of iron in fe3o4?
Why is the chemical formula of iron oxide Fe3O4 when the valency of iron is 2,3 and that of oxygen is 2.
