Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected greatly for its chemical properties to be investigated . When a substance goes under a chemical reaction, the properties will change drastically, resulting in chemical change . However, a catalytic property would also be a chemical property . </P> <P> Chemical properties can be contrasted with physical properties, which can be discerned without changing the substance's structure . However, for many properties within the scope of physical chemistry, and other disciplines at the boundary between chemistry and physics, the distinction may be a matter of researcher's perspective . Material properties, both physical and chemical, can be viewed as supervenient; i.e., secondary to the underlying reality . Several layers of superveniency are possible . </P>

A chemical property is determined by the following
