Chemical properties are those properties that tell us about what a substance can do as regards to whether or not the substance reacts with other substances.
Examples are flammability, rusting of iron, precipitation, decomposition of water by an electric current.
The ability to decompose and reactivity are chemical properties of a substance.
Physical properties tells us everything about what a substance is when no change is occurring to its constituents.
Examples are state of matter, color, odor, taste, texture, hardness e.t.c
