H2O is a compound. So it's second one.
The name of CuO is copper II oxide and its bond type is ionic or electrovalent bond.
<h3>What is electrovalent bond?</h3>
An ionic or electrovalent bond is the type of chemical bond where two atoms or molecules are connected to each other by electrostatic attraction.
This electrostatic attraction is as a result of the transfer of electrons from the metallic element to the non-metal.
According to this question, CuO is a chemical compound consisting of two elements namely; copper and oxygen. The compound name is copper II oxide.
Copper as a metal transfers electrons to oxygen atoms, hence, an ionic bond is formed between the molecules.
