Chemical Changes
In chemical change, new substances are formed.
The new substances formed have properties entirely different from the original substances.
In a chemical change, a substance undergoes a change in its chemical properties.
Chemical changes are also called chemical reactions.
In chemical change, the changes are permanent which can usually not be reversed to form the original substances.
For example: Curdling of milk.
