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
It does change its physical look but it does not change chemically.
A reactant
Chemical reactions are chemical processes.
i want to know the answer.............................................................................................................................................................................. .................................................................................................................................. ................................................................................................................................................ .................................................................................................................................................... ................................................................................................................................. ...................................................................................................................................... but I don't!
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.

A chemical reaction
This is called reaction rate.
A substance that undergoes change in a chemical reaction is called a reactant.
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.

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.
