Answer 1

The correct list that only includes terms that describe oxygen gas (O2) is:

**element, molecule, pure substance**

Here's why:

- **Element**: O2 is an elemental form of oxygen.
- **Molecule**: O2 consists of two oxygen atoms bonded together, making it a molecule.
- **Pure substance**: O2 is a pure substance because it is made up of only one type of molecule.

The other options contain terms that do not accurately describe O2.
