Pure water is H2O, liquid at room temperature.
It is matter. because H2O means water, and water is one form of matter cause its liquid.
Gaseous matter such as H2O, SO2, CO2. Solid materials such as ash, lava, bombs.
You think probable to a chemical compound.A chemical compound may be a gas (CH4), a liquid H2O) or a solid (U3O8).
H2O represents the chemical formula for water, which is a chemical compound. In terms of type of equation, it is a molecular formula that shows the number and type of atoms present in a molecule of water.

H2O and CO2
The states of matter of H2O (water) are solid (ice), liquid (water), and gas (water vapor). Each state is determined by the temperature and pressure conditions under which the water exists.
h2o
Matter that is an element consists of only one type of atom, such as oxygen or gold. Compounds consist of two or more different elements chemically bonded together, such as water (H2O) or carbon dioxide (CO2).
Water is homogeneous. ------------------------------------------------- Actually natural water is heterogeneous as it is a mixture of H2O and a very tiny amount of D2O. The D2O (i.e. heavy water) has higher mass than H2O and slightly different chemical properties. However for ordinary practical purposes the presence of this D2O can usually be ignored.
Hydrochloric acid is an aqueous solution of hydrogen chloride (HCl) and water (H2O). The acid is a liquid matter.
