What is the formula of K2S?
Is K2S correct?
e.g, K2S is potassium sulfide. … dipotassium sulfide is incorrect because potassium ion is always K+1 and sulfide is always S-2 and therefore the only way to combine them is K2S.
How would you write K2S?
Why is it K2S?
The 2 in K2S indicates that there are two potassiums present in the compound. We need these two potassiums so the compound can have a charge of 0.
Is K2S ionic or covalent?

Why is aluminum oxide Al2O3?
Since the overall charge of a compound must always be equal to zero (neutral), we need 2 aluminum atoms and 3 oxygen atoms in order to balance out the charge and make the compound neutral. This means that the chemical formula for aluminum oxide is simply Al2 O3.
What is Fe3O4 10?
Fe3O4 is the chemical formula of Iron (II, III) oxide which has four oxygen atoms, three iron atoms.
What are the reactants of Fe3O4?
Fe3O4 Is actually a combination of two compounds,Fe2O3 and FeO. The First is called ferric oxide and the second is ferrous oxide.. It is known as Ferrous ferric oxide,ferroso ferric oxide,magnetite,black iron oxide.. Fe3O4 Is actually a combination of two compounds,Fe2O3 and FeO.
What is Fe3O4 made of?
Ferrosoferric oxide is an iron oxide. Iron (II,III) oxide (Fe3O4). It is a black ore of IRON that forms opaque crystals and exerts strong magnetism.
Is Fe3O4 ferrimagnetic?
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 write Fe3O4?
Fe2O3 is written as iron(II) oxide while Fe3O4 is written as iron(II,III) oxide.
How do you read Fe3O4?
What is ferromagnetism and ferrimagnetism?
Ferromagnetism is the property of materials being attracted to magnets. Ferrimagnetism is the magnetic property of materials having atomic moments aligned in opposite directions. Curie Temperature. The Curie temperature of ferromagnetic materials is higher when compared to ferrimagnetic material.
Which type of compound is Fe3O4 ferrimagnetic?
Iron(II,III) oxide is the chemical compound with formula Fe3O4. It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe2O3) which also occurs naturally as the mineral hematite.
Why is Fe3O4 paramagnetic at 850k?
Ferrimagnetic Fe3O4 on heating to 850 K becomes paramagnetic. This is due to alignment of spins in one direction on heating.
