Answer:
The correct chemical formula for water is H2O.
Step-by-step explanation:
Two hydrogen atoms (H) are joined to one oxygen atom (O) to form the water molecule that is represented by the symbol H2O. In the discipline of chemistry, this formula is widely established and recognised. The proportion of elements in a water molecule is represented by the formula H2O. The subscript "2" denotes the presence of two hydrogen atoms in each molecule, while the "H" stands for hydrogen. The oxygen that is joined to the hydrogen atoms is denoted by the letter "O". As a result, there are two hydrogen atoms and one oxygen atom in each water molecule.
