A chemical reaction occurs when chemicals combine to form new substances with new properties. Burning is a rapid type of chemical reaction that produces large amounts of heat and light. An example of a fast chemical reaction is an explosion, such as the exploding of fireworks or a bomb. An example of a slow chemical reaction is rusting (or oxidisation). One of the chemicals produced during burning is carbon dioxide, which we now refer to as a 'greenhouse gas'.
