iron (Fe), sulphur (S), oxygen (O)
Two elements, iron and sulpur, make up a molecule of the compound iron sulphide.
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
Iron plus sulfur react to form iron sulfide. This is a chemical reaction that takes place when iron powder is mixed with powdered sulfur in the presence of heat. The reaction produces a black compound called iron sulfide.
The rocks in earths mantel are made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. Iron, calcium, sodium, aluminum, and potassium are also present. The elements occur in rocks as oxides.
Iron sulphate is expressed as FeSO4 and hydrogen is simply H. So to answer your question, iron sulphate plus hydrogen is made up of iron, sulfur, oxygen and hydrogen.
Two elements, iron and sulpur, make up a molecule of the compound iron sulphide.
Iron is, itself, and element. It is not a compound of two elements.
Iron(II) Sulphate or Iron(III) Sulphate Iron (II) Sulphate also goes by the name 'Ferrous Sulphate , and has the formula FeSO4 . Iron (III) Sulphate also goes by the name 'Ferric Sulphate , and has the formula Fe2(SO4)3 They are two entirely different compounds. .
A mixture is a collection of various elements which have not ionically bonded. A compound is when those elements are heated up and join together. Mixture = Iron and Sulphur Compound = Iron Sulphate
iron and sulfur
Magnesium sulfate is composed of the atoms of magnesium, sulfur and oxygen.
There are two compounds , that are sulphates of iron. It depends on the oxidation state of the iron cation. Oxid'n state '2' ; Ferrous sulphate ;Iron(II) sulphate ; (FeSO4) (Pale green colour) Oxid'n state '3' ; Ferric sulphate ;Iron(III) sulphate ; (Fe2(SO4)3) (Brown colour).
Iron and oxygen
Magnesium sulfate is composed of the atoms of magnesium, sulfur and oxygen.
Iron is a magnet so it could be used for separating bits of metal from crushed up rock? True for iron, and separating bits of iron. But iron sulphate is not magnetic.
Iron sulfate is a compound, not an element. It is made up of iron (Fe) and sulfate (SO4) ions, which combine to form the compound FeSO4.
