The example that illustrates a chemical change is **burning wood**.
In a chemical change, the substance's chemical composition is altered, resulting in the formation of new substances. When wood burns, it undergoes a chemical reaction with oxygen that produces ash, smoke, and various gases. In contrast, shredding paper, smashing a soda can, and chopping wood are all physical changes, where the substances involved remain chemically the same despite changes in their form or appearance.
