which of these is a molecule and is also 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:
$H_2O$ (water with two atoms of hydrogen and one atom of oxygen joined together chemically)
Explanation:
Step1: Define molecule and compound
A molecule is two or more atoms joined chemically. A compound is a molecule made of different - element atoms.
Step2: Analyze $H_2O$
$H_2O$ is a molecule as it has multiple atoms joined chemically. It is also a compound since it has hydrogen and oxygen, two different elements.
Step3: Analyze $O_2$
$O_2$ is a molecule as two oxygen atoms are joined chemically. But it is not a compound because it consists of only one - type of element (oxygen).
