Chemical changes take place on the molecular level. A chemical change produces a new substance. It is a permanent and irreversible change. Examples of chemical changes include combustion (burning), cooking an egg, rusting of an iron pan, and mixing hydrochloric acid and sodium hydroxide to make salt and water.
