chain reaction
(also Nuclear chain reaction) 1 A reaction that stimulates its own repetition 2 For example, nuclear reaction occurs when neutrons released from a split atom such as a uranium-235 (U235) nucleus go on to fission other nuclei This reaction produces additional neutrons that cause more fissions, which release still more neutrons to cause even more fissions, which release even more neutrons, and so on See Fission
chain reaction
The continuing process of nuclear fissioning in which the neutrons released from a fission trigger at least one other nuclear fission In a nuclear weapon, an extremely rapid, multiplying chain reaction causes the explosive release of energy In a reactor, the pace of the chain reaction is controlled to produce heat (in a power reactor) or large quantities of neutrons (in a research or production reactor)

chain reaction
A reaction in which one of the agents necessary to the reaction is itself produced by the reaction, thus causing like reactions
chain reaction
A chain reaction is a series of events, each of which causes the next. The powder immediately ignited and set off a chain reaction of explosions. Process yielding products that initiate further processes of the same kind. Nuclear chain reactions are a series of nuclear fissions initiated by neutrons produced in a preceding fission. A critical mass, large enough to allow more than one fission-produced neutron to be captured, is necessary for the chain reaction to be self-sustaining. Uncontrolled chain reactions, as in an atomic bomb, occur when large numbers of neutrons are present and the reactions multiply very quickly. Nuclear reactors control their reactions through the careful distribution of the fissionable material and insertion of neutron-absorbing materials
chain reaction
A chain reaction is a series of chemical changes, each of which causes the next
chain reaction
series of reactions in which each is directly caused by the one before it
chain reaction
A reaction which, once started, will produce a material or substance necessary to continue the reaction An example is nuclear fission Once a fission reaction is started, neutrons are released, which cause more nuclei to undergo fission, which release more neutrons, and so on
chain reaction
A reaction that initiates its own repetition In a fission reaction, free neutrons are produced which fly off and strike other nuclei, causing them to split and send off yet more free neutrons The fission will continue as long as there are enough free neutrons carrying the right amount of energy

chain reaction

chain reaction
A process in which some of the neutrons released in one fission event cause other fission events that in turn release neutrons
chain reaction
a self-sustaining reaction in which the products of one reaction event stimulate further reaction events
chain reaction
A large number of nuclear fissions, taking place within a certain mass of a fissionable isotope, that release a great quantity of energy in a short time
chain reaction
A process in which one nuclear transformation sets up conditions for similar nuclear transformation in another atom Thus, when fission occurs in uranium atoms, neutrons are released, which in turn produce fission in other uranium atoms
chemical reaction
a natural process in which the atoms of chemicals mix and arrange themselves differently to form new substances. Any chemical process in which substances are changed into different ones, with different properties, as distinct from changing position or form (phase). Chemical reactions involve the rupture or rearrangement of the bonds holding atoms together (see bonding), never atomic nuclei. The total mass and number of atoms of all reactants equals those of all products, and energy is almost always consumed or liberated (see heat of reaction). The speed of reactions varies (see reaction rate). Understanding their mechanisms lets chemists alter reaction conditions to optimize the rate or the amount of a given product; the reversibility of the reaction and the presence of competing reactions and intermediate products complicate these studies. Reactions can be syntheses, decompositions, or rearrangements, or they can be additions, eliminations, or substitutions. Examples include oxidation-reduction, polymerization, ionization (see ion), combustion (burning), hydrolysis, and acid-base reactions

a chemical reaction accompanied by the absorption of heat
exoergic reaction
a nuclear reaction accompanied by the evolution of energy
exothermic reaction
a chemical reaction accompanied by the evolution of heat
heat of reaction
Amount of heat that must be added or removed during a chemical reaction to keep all substances involved at the same temperature. If it is positive (heat must be added), the reaction is endothermic; if it is negative (heat is given off), the reaction is exothermic. Accurate heat of reaction values are needed for proper design of equipment used in chemical processes; they are usually estimated from compiled tables of thermodynamics data (heats of formation and heats of combustion of many known materials). The activation energy is unrelated to the heat of reaction

photochemical reaction
a chemical reaction produced by the action of light
photochemical reaction
Chemical reaction initiated by absorption of energy in the form of visible (light), ultraviolet, or infrared radiation. Primary photochemical processes occur as an immediate result, and secondary processes may follow. The most important example is photosynthesis. Vision depends on photochemical reactions that occur in the eye (see retina; rhodopsin). In photographic film and paper, light activates their silver salts to a state that is easy to reduce to metallic silver grains during development. Bleaching of laundry, tanning of human skin, formation of Earth's ozone layer, and many industrial reactions are also photochemical. Certain air pollutants (see smog) become more reactive and form noxious compounds in photochemical reactions
polymerase chain reaction
laboratory technique used to replicate segments of DNA by repeatedly splitting the DNA strands and duplicating them with a DNA polymerase enzyme, PCR (Molecular Biology)
polymerase chain reaction
A technique for amplifying DNA sequences in vitro by separating the DNA into two strands and incubating it with oligonucleotide primers and DNA polymerase. It can amplify a specific sequence of DNA by as many as one billion times and is important in biotechnology, forensics, medicine, and genetic research. Laboratory technique used to make numerous copies of specific DNA segments quickly and accurately. These are needed for various experiments and procedures in molecular biology, forensic analysis (DNA fingerprinting), evolutionary biology (to amplify DNA fragments found in ancient specimens), and medicine (to diagnose genetic disease or detect low viral counts). Invented by Kary Mullis, PCR requires a DNA template (as little as one molecule) to copy, nucleotides to build the copies, and the enzyme DNA polymerase to catalyze the formation of bonds between the nucleotide monomers. Each three-step cycle (separating the two strands of the DNA double helix, marking the ends of the segment to be copied, and catalyzing the formation of bonds), which takes only minutes to complete, doubles the number of DNA strands present in the reaction medium. Repetition of this cycle many times results in an exponential increase in the amount of DNA
