What is a chemical reaction? - BBC Bitesize

WebA chemical reaction is a process in which one or more substances are converted to one or more different substances. In the reaction, the atoms of the starting substances are rearranged, forming new substances that have different properties. The number of atoms and the amount of mass are the same before and after the reaction takes place; thus ...
