Answer to Problem 36R

The correct option is (C).

Explanation of Solution

Introduction:

A chemical formula is a way to provide knowledge on the chemical quantities of atoms that make up a given chemical substance or molecule.

The chemical formula of the given compound is $\text{CuO}$ . In this case, the positive part of the compound is copper. The negative part of the compound is oxygen. The oxygen belongs to group 16 of the periodic table and needs 2 electrons to complete its outermost shell. However, elements of group 16 shows an oxidation number of +3. Since the compound as a whole should have zero net charge, therefore, the charge on the copper should be +2.

Therefore, the name of the compound is copper (II) Oxide.

Conclusion:

Hence, the name of the compound is copper (II) Oxide.
