<h3>
Explanation:</h3>
To answer this question we need to know what is a compound.
- A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
- A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
- Additionally, the chemical formula shows the number of each type of atom in a molecule.
- In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.
