Concept explainers
Interpretation:
The evidence whichdoes not represent a chemical change needs to be identified.
Concept introduction:
Physical property is the characteristic of any substance measured or observed without losing the identity of thesubstance. It includes color, hardness, density, melting and boiling points. On the other hand, chemical property describes the ability of any substance to undergo the specific chemical change.

Answer to Problem 9STP
The correct option is D.
Explanation of Solution
Chemical properties can be describes as the ability of substance undergoing specific chemical change. In accordance with the law of mass conservation, mass of a substance can neither be created nor destroyed during a
The statement ‘‘Change in the total mass of the substances involved in the reaction’’ is not correct in accordance with the law of conservation of mass. Hence, the correct option is D.
