Question

Which of the following correctly labels these substances? Oxygen (O2), Carbon dioxide (CO2), Nitrogen (N2), Water (H2O).
Options
A All are both molecules and compounds.
B O2 and N2 are molecules only; CO2 and H2O are both molecules and compounds.
Correct Answer
C O2 and N2 are compounds only; CO2 and H2O are molecules only.
D All are elements.
Correct Answer

Option B is the correct answer.

Detailed Explanation

O2 and N2 are molecules because they consist of two atoms of the same element bonded together, but they are not compounds because they are not composed of different elements. CO2 and H2O are molecules (two or more atoms bonded) and also compounds (contain two different elements).

Hint

A molecule is any two or more atoms bonded; a compound requires atoms from different elements.
