Answer:
Copper(II) sulfate.
Explanations:
Before we name the given compound, we need to know what chemical compounds are. Chemical compounds are chemical substances composed of molecules formed from atoms of an element and held together by a chemical bond.
Given the chemical compound CuSO4, this compound contains copper, sulfur, and oxygen element.
The molecular compound CuSO4 is named with the first element first and then the second element by using the stem of the element name plus the suffix -ate
The compound name for CuSo4 will therefore be Copper(II) sulfate. The roman numeral of (II) comes from the sum of the oxidation state of the element.
Note that the oxygen atoms have a -2 oxidation number, and sulfur has a +6, oxidation number to have (4 * -2) + 6 = -2. This makes copper have an oxidation number of +2.
