Iron, sulfur and oxygen are present in ferrous sulfide.
Iron(II) sulphide
3.2g ..... assuming it is iron (II) Sulphide FeS2. The relative atomic mass of iron is 56, sulphur is 32, so the ratio of masses of these two elements IN THE FORMULA = 56 : 64. If 2.8g of iron was used then, from the ratio, this will react with 3.2g of sulphur.
Pyrite (A.K.A. Fool's gold) isn't an element, its formula is FeS2 (iron (II) disulfide) Pyrite is classed as a mineral.
I believe you mean iron pyrophosphate, Fe4(P2O7)3 This is the pyrophosphoric acid salt of iron(II). It contains the elements iron, phosphorus and oxygen.
The sulfur is present as the [S2]2- ion iron is present as iron(II). The average ox # of S is therefore -1
This is the chemical formula of iron(II) sulfate.
If you mean, "What elements make up iron sulphide," then they are Iron and Sulphur. Various 'types' of iron sulphide exist, including FeS (iron (II) sulphide), FeS2 (commonly known as pyrite, iron (II) disulphide or fool's gold), and Fe2S3 (iron (III) sulphide).
iron sulphide, iron(II) sulphide or ferrous sulphide. Iron sulphide is ambiguous however and could refer to any one of a range of iron sulphur compounds,including Fe3S4 and Fe2S3
Iron(II) sulphide: FeS. Iron sulphide is a synonym, but the first expression is more correct. Iron(III) sulphide: Fe2S3. Other forms of natural iron sulphides are known: see the link below.
Fe2SO4 for Iron(II) sulfate and Fe2(SO4)3 for Fe(III)sulfate.
Iron(II) sulphide
Iron (ii) _________ Sulphur ____________ Iron Sulphide Fe _____________ S _________________ FeS Fe2S3
Iron (II) sulfate is the correct name for this compound. The Fe ion has a charge of 2 and so does the sulfate ion, so there is no subscript after them.
iron II sulfide
Two iron chlorides are known: iron(II) chloride and iron(III) chloride, FeCl2 and FeCl3.
The formula for Lead Sulfide (or Lead Sulphide) is either: PbS for Lead(II) Sulphide, or PbS2 for Lead(IV) Sulphide.
FeS is not a chemical equation but a chemical formula; FeS is the chemical formula of iron sulfide.
