When a pure substance undergoes a chemical change, its molecular structure is altered, resulting in the formation of one or more new substances with different chemical properties. This process is typically accompanied by observable signs such as color change, gas production, or temperature change. Unlike physical changes, where the substance retains its original identity, chemical changes are often irreversible under normal conditions. Examples include combustion, rusting, and fermentation.
