Iron is needed to produce iron sulphate.
Iron sulfate can be made by reacting iron metal with sulfuric acid. The balanced chemical equation for this reaction is 3 Fe + 4 H2SO4 → Fe2(SO4)3 + 4 H2.
You would need to react iron with sulfuric acid (H2SO4) to produce iron sulfate (FeSO4).
Iron ore was traditionally used to make metal poles. These metal poles would be used as support beams in buildings for example.
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.
Iron Oxide + Sulphuric Acid = Iron Sulphate + Water
To make ferrous sulfate, also known as iron(II) sulfate, start with iron filings or iron sulfate heptahydrate crystals. Dissolve the iron source in sulfuric acid and oxidize it to form ferrous sulfate solution. Then, crystallize the solution to obtain solid ferrous sulfate crystals.
Two elements, iron and sulpur, make up a molecule of the compound iron sulphide.
There is iron.
I believe it would have been cast iron, but that is only my guess.
It is highly unlikely that you can make a hole in a sixpence with a soldering iron due to the hardness of the metal. Sixpences are typically made of a durable metal alloy that would not easily melt or create a hole with a soldering iron. It would be more practical to use a drill or specialized tools for this purpose.
I think steel Because it is versatile Building material
Iron is a very hard metal so, it would make a great hammer.
