What is the difference between the chemical and physical properties for sodium chloride?
For all materials physical properties are related to some characteristics as density, hardness, refractive index etc. and the chemical properties are related to some characteristics as chemical reactivity, flammability, oxydation etc. Physical properties are characterized by getting back the original material by changing its form, state, etc. Chemical properties are characterized by a complete change in the material itself i.e. you cannot get back the same material.
Explain the difference between the two kinds of substances?
