Explanation:

Water has a formula which represents two hydrogen atoms are attached to one oxygen atom. Therefore, the formula of water is H_{2}O.

Salt is also known as sodium chloride. Its formula represents that one sodium atom is attached to one chlorine atom, therefore, its formula is NaCl.

Carbon dioxide has a formula which represents one carbon atom is attached to two oxygen atoms. Therefore, its formula is CO_{2}.

Methane has a formula which represents one carbon atom is attached to four hydrogen atoms. Therefore, its formula is CH_{4}.

Thus, we can conclude that H_{2}O is water, CO_{2} is carbon dioxide, NaCl is salt, and CH_{4} is methane.
