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:

Step1: Determine bond type between Fe and S

Iron (Fe) is a metal (electronegativity \(1.8\)) and sulfur (S) is a non - metal (electronegativity \(2.5\)). The electronegativity difference \(\Delta\chi=2.5 - 1.8=0.7\). Since metals and non - metals with a significant electronegativity difference (usually \(\Delta\chi>0.5\) for ionic character in a simple sense for binary compounds) form ionic bonds.

Step2: Determine bond type between S and O

Sulfur (S, \(2.5\)) and oxygen (O, \(3.5\)) are both non - metals. The electronegativity difference \(\Delta\chi = 3.5-2.5 = 1.0\). Non - metals with an electronegativity difference less than \(1.7\) (a general rule for covalent bonds) form covalent bonds. In the sulfate ion (\(SO_{4}^{2-}\)), S and O are covalently bonded.

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

Answer:

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