chain reaction n 1.(General Physics) a process in which a neutron colliding with an atomic nucleus causes fission and the ejection of one or more other neutrons, which induce other nuclei to split 2.(Chemistry) a chemical reaction in which the product of one step is a reactant in the fo...
Chain reaction (physics) A succession of generation after generation of acts of division (called fission) of certain heavy nuclei. The fission process releases about 200 MeV (3.2 × 10-4 erg = 3.2 × 10-11 joule) in the form of energetic particles including two or three neutrons. Some of...
The chemical reaction between hydrogen gas and oxygen gas to form water is another example of a chain reaction. In the reaction, one hydrogen atom is replaced by another as well as two OH radicals. The propagation of the reaction can lead to an explosion. Chain Reaction Steps A typical chai...

Nuclear Physics: Control of the Chain Reaction involved in Fission of the Uranium NucleusIT has recently been shown that the numberof neutrons liberatedin the nuclear fission of a uranium nucleus is sufficiently high to make the realization of a self-perpetuating reaction chain seem possible. The ...

In this section we consider the basic definitions of molecular weight distribution in chain polymerization, emphasizing particularly the relationship of molecular weight distribution to the mechanisms of the polymerization reaction. Other more fundamental aspects of distribution functions, relevant to the chara...
The reaction mixture was heated to 60 °C, and the course of the reaction was monitored by the gas chromatography. After the starting materials were consumed, the volatiles were evaporated, the solid crude product was dissolved in diethyl ether, and the obtained solution was filtered through ...
