You probably already know the names of some molecules. identify which compound (water, salt, carbon dioxide, or methane) corresponds to each of the following chemical formulas. h2o is . co2 is . nacl is . ch4 is .

Explanation:

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

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 .

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

Thus, we can conclude that is water, is carbon dioxide, NaCl is salt, and is methane.

false

because it does not have the potential to be entirely used up
