which of these is a molecule but not a compound?\no₂ (two atoms of oxygen joined together chemically)\nh₂o (water with two atoms of hydrogen and one atom of oxygen joined together chemically)
Answer
Brief Explanations:
A molecule is two or more atoms chemically bonded. A compound is a molecule made of different - element atoms. $O_2$ is a molecule of two oxygen atoms (same - element atoms), so it's not a compound. $H_2O$ is a molecule with different - element atoms (hydrogen and oxygen), so it's a compound.
Answer:
$O_2$ (two atoms of oxygen joined together chemically)
