Answer:

a. Copper (I)Iodide.

b.Iron (III)Hydrogen sulfate.

c. Magnesium Chromate.

Explanation:

a.Cu I

Copper(I) Iodide

We know that charge on iodide ion is -1 and charge on +1.

Hence, the correct name is copper (I)Iodide.

b.[tex]Fe(HSO_4)_3[/tex]

We know that charge on hydrogen sulfate ion is -1

and charge on iron is +3

Then , it require 3 ion of hydrogen sulfate to form iron Hydrogen sulfate.

Hence, the correct name is Iron (III)hydrogen sulfate.

c.[tex]MgCr_2O_7[/tex]

[tex]Cr_2O_7^{-2}[/tex] is Chromate ion

The charge on magnesium is +2.

Hence, the correct name is Magnesium Chromate.
