Question

which statement describes the bonds in iron sulfate (feso₄)?
(1 point)
fe and s are covalently bonded, and s and o also have a covalent bond are covalently bonded.
fe and s are ionically bonded, while s and o are covalently bonded.
fe and s are ionically bonded, and s and o also are ionically bonded.
fe and s are covalently bonded, while s and o are ionically bonded.

Explanation:

Iron sulfate ($FeSO_4$) is an ionic compound. In ionic compounds, metal (here $Fe$, a metal) and non - metal (here $S$ in the sulfate ion) are ionically bonded. In the sulfate ion ($SO_4^{2 - }$), sulfur ($S$) and oxygen ($O$) are non - metals. Non - metals share electrons to form covalent bonds. So, $Fe$ (metal) and $S$ (in the sulfate ion, non - metal) have an ionic bond, and $S$ and $O$ (both non - metals) have covalent bonds.

Answer:

Fe and S are ionically bonded, while S and O are covalently bonded.
