the difference is that the formula does not have the same categories as the chemical compound does
Because as a rule only a chemical compound has a chemical formula; a mixture contain two or many componds and each compound has a different chemical formula.
The compound formed between iron and selenium is iron(II) selenide, with the chemical formula FeSe.
The chemical formula of the compound formed between cobalt (III) and the bromide ion it would be CoBr3, if this compound exist !
Isomers.
A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a chemical compound.So this being said, that basically means the chemical formula represents the atoms that are bonded to one another (An atom is classified according to chemical element and isotope more specifically)
Because as a rule only a chemical compound has a chemical formula; a mixture contain two or many componds and each compound has a different chemical formula.
