which of these is a molecule but not a compound?\nh₂o (water with two atoms of hydrogen and one atom of oxygen joined together chemically)\no₂ (two atoms of oxygen joined together chemically)
Answer
Answer:
$O_2$
Explanation:
Step1: Define molecule and compound
A molecule is two or more atoms chemically bonded. A compound is a molecule made of different - element atoms.
Step2: Analyze $H_2O$
$H_2O$ has hydrogen and oxygen atoms, so it is a compound.
Step3: Analyze $O_2$
$O_2$ is a molecule as it has two oxygen atoms bonded, but it is not a compound since both atoms are of the same element (oxygen).
