Both are molecules. cap n cap o sub 2 is also a compound. Both are molecules. N2 is also a compound. Both are molecules. cap n sub 2 is also a compound. Both are elements.

Answer 1

The best statement that describes the substances N₂ and NO₂ is: **Both are molecules. NO₂ is also a compound.**

Here's the reasoning:
- N₂ (nitrogen gas) is a molecule made up of two nitrogen atoms, and it is considered an element because it consists of only one type of atom.
- NO₂ (nitrogen dioxide) is a molecule that consists of nitrogen and oxygen atoms, and it is classified as a compound because it is made up of more than one type of element.

Thus, the correct response should acknowledge that N₂ is an element (specifically a diatomic molecule), while NO₂ is a compound that is also a molecule.
