best_answer

(c) Burning of coal is a chemical change because it involves the combustion of coal in the presence of oxygen, resulting in the formation of new substances such as carbon dioxide (CO?), carbon monoxide (CO), and ash. This process is irreversible, and the chemical composition of coal changes permanently during the reaction.
