can be split into hydrogen and oxygen chemical property
is liquid at room temperature physical property
has a density of 1.0 g/cm³ physical property
reacts with certain metals chemical property
Explanation:
The physical properties of matter are the properties that occur when no change is occurring to a matter. They are usually observed with our senses or some simple laboratory experiments.
Some of the physical properties are boiling point, density, state of matter, e.t.c
The chemical properties are the properties that occurs when a matter undergoes some chemical changes.
For example rusting, decomposition, reactivity e.t.c
