Responses
There is one molecule in the compound.
There is one molecule in the compound.
There are two oxygen atoms in the compound.
There are two oxygen atoms in the compound.
There is one oxygen atom in the compound.
There is one oxygen atom in the compound.
There are no oxygen atoms in the compound.
There is one oxygen atom in the compound.
The lack of a subscript after the "O" indicates that there is one oxygen atom in the compound.
The lack of a subscript after the O in the formula for water (H2O) indicates that there is only one oxygen atom in the compound. To understand this, we can break down the formula:
H2O means that there are 2 hydrogen (H) atoms and 1 oxygen (O) atom. The subscript 2 after the H indicates that there are two hydrogen atoms. However, there is no subscript after the O, which means there is only one oxygen atom.
Therefore, the correct response is: There is one oxygen atom in the compound.
