How do you define a chemical reaction
WebPaulnasca. A 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 ... Weboxidation-reduction reaction, also called redox reaction, any chemical reaction in which the oxidation number of a participating chemical species changes. The term covers a large and diverse body of processes. Many oxidation-reduction reactions are as common and familiar as fire, the rusting and dissolution of metals, the browning of fruit, and respiration and …
