Question

what is chain reaction? give an example

Answer 1

chain reaction. In chemistry and physics, a self-sustaining series of reactions. In a chain reaction in a uranium-based nuclear reactor, for example, a single neutron causes the nucleus of a uranium atom to undergo fission. In the process, two or three more neutrons are released.

Answer 2

A succession of reactions, usually involving free radicals, where the products of one stage ard the reactants of the next. A chain reaction is characterized by the continual generation of reactive substances.
Example the oxidation of edible oils.
