The correct statement that describes the bonds in iron sulfate (FeSO₄) is:
D. Fe and S are ionically bonded, while S and O are covalently bonded.
In iron sulfate, the iron (Fe) forms a cation (Fe²⁺), which is ionically bonded to the sulfate ion (SO₄²⁻). Within the sulfate ion, sulfur (S) and oxygen (O) are covalently bonded to each other.
