define chemical properties. then give 3 examples. then explain the reversibility and fundamental differences.

A property of a substance relating to its chemical reactivity is called chemical properties.Examples of chemical properties include flammability, toxicity, acidity, reactivity and heat of combustion.A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. Therefore, if two things are fundamentally different, this means that they are different at their very foundation—they are different from the ground up. They have been built on entirely separate things, indicating that the difference between them isn't minor or something that can be changed.
