# chain reactionZoomA-Z

## Subject - Inorganic Chemistry, Organic Chemistry, Macromolecular Chemistry

Chain reactions are processes in which particles required to initiate a reaction are constantly re-generated, thereby again triggering similar processes. Such processes take part in many chemical reactions. Examples are the chlorine-oxyhydrogen gas reaction, combustion processes and photodegradation by $OH$ radicals, polymerizations, and chain reactions in a nuclear reactor.
