What are the five examples of Chemical Changes?

The change in which chemical properties of the matter change is known as chemical change.

During a chemical reaction, the chemical bond between the molecules broken, rearranged, and new bonds are formed resulting in the formation of the new compound.

For example, photosynthesis reaction is a chemical change as carbon dioxide and water in the presence of sunlight and chlorophyll to give sugar molecule and oxygen as a product. Here, sugar once formed cannot be converted back to carbon dioxide and water easily. As the new compound is formed from the reaction between water and carbon dioxide, it is a chemical change.

Other Examples: Digestion of food, burning of petrol and diesel, rusting, preparation of tea and coffee, burning of magnesium ribbon, the ripening of fruits, etc.
