It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
A chemical change involve a change of composition.
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
This is called reaction rate.
reactants
That is correct, a candle (or the material of which it is composed, which is usually paraffin) undergoes a chemical change when it burns.

The chemical composition of a substance does not change when it undergoes a physical change.

A catalyst does no change chemically.
For example a chemical reaction with an alkali metal.
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
