FeS, though that is not a very stable form.
I believe it's Fe.
The chemical symbol for iron is Fe and the chemical symbol for nickel is Ni.
Chemical, as rust is iron oxide. The iron is turning from iron to iron oxide, which (as you can see) is a chemical change. In general, a colour change usually indicates a chemical change.
Yes. Iron corrodes because oxygen ions attach to iron atoms to make iron oxide
I think it`s a chemical change.
Iron fillings are pure iron - until they start rusting. So their formula is Fe.
Iron (Fe) is a chemical element.
Rusting of iron is chemical. It is the combination of oxygen with the iron, creating a different chemical: rust or iron oxide.
FeS is not a chemical equation but a chemical formula; FeS is the chemical formula of iron sulfide.
Iron is a chemical element, not a "change" !
rust is a chemical change for iron
Iron is a chemical element, not a "change".
The chemical formula of iron pyrite is FeS2.
Iron, as an element, is its own chemical. He means chemical formula, in that case it's "Fe."
Iron (Fe) is a chemical element, water is a chemical compound (H2O).
The chemical symbol for iron is Fe and the chemical symbol for nickel is Ni.
Iron rusting is a chemical change.
Iron is a chemical element, not a change.
