Yes because, If you had a BRAND NEW bike, And it wasnt rusted or had any cracks at ALL, It would be obvious that if in a couple years it was completely rusted it would be noticable, In other words ( It is obvious that a substance undergoes a chemicaL WHICH MEANS that a chemical change has happened.)

This is called reaction rate.
A substance that undergoes change in a chemical reaction is called a reactant.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped

If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
It does change its physical look but it does not change chemically.
The chemical composition of a substance does not change when it undergoes a physical change.
