Detailed Solution

The above statement is true.
A change in which the chemical properties of a substance get altered is called a chemical change. The chemical change is also called a chemical reaction that is generally irreversible. In a chemical change, one or more new substances always get formed during the reaction. The burning of wood and paper is an example of chemical change, as it is an irreversible reaction in which a new substance named ash is obtained with a different chemical composition from that of wood or paper.
