Physical
H20
The chemical formula H2O represents the chemical composition of water, so it is a chemical property. It describes the substance's composition and the ratio of atoms in the molecule, rather than a physical characteristic like color or texture.
The chemical formula H2O itself is a chemical property because it represents the specific composition of water molecules. Physical properties, on the other hand, describe characteristics that can be observed or measured without changing the substance's chemical identity.
H20 is a chemical property because it refers to the chemical formula for water, which consists of two hydrogen atoms bonded to one oxygen atom. This composition describes the specific arrangement of atoms in a water molecule, which is a characteristic of its chemical identity.

2 H2O is the chemical formula of two molecules of water, not a reaction.
For example - dihydrogen oxide.
To write a sentence using the term "chemical formula," you can say: "H2O is the chemical formula for water." This simple example showcases a chemical formula and relates it to a common substance.
Sprite's chemical formula is C12H22O11. It is a carbonated soft drink produced by the Coca-Cola Company.
A chemical reaction changes the actual chemical make-up of a molecule while a physical reaction only changed the physical state of a molecule, the atomic make-up in the molecule stays the same. (ex: H20(l) ---heat--> H20(g))
