A chain reaction is a sequence of reactions where a reactive product or by- product causes additional reactions to take place. In a chain reaction, positive. Chain Reaction (deutsch: Kettenreaktion) bezeichnet unter anderem: Außer Kontrolle (), Originaltitel Chain Reaction, ein Action-Thriller; Chain Reaction. Dominoes, Kapla, popsicle stick bombs, cobra weaves, chain reactions, and other cool tricks! Click to tweet. In , Walther Nernst proposed that the photochemical reaction of hydrogen and chlorine is a chain reaction in order to explain the large quantum yield , meaning that one photon of light is responsible for the formation of as many as 10 6 molecules of the product HCl. Navigation Hauptseite Themenportale Von A bis Z Zufälliger Artikel. But don't worry that you won't have the right bricks; we worked with the folks at LEGO to make sure you'll need only the most common bricks, and that there are plenty of substitutes. In , Danish and Dutch scientists Christian Christiansen and Hendrik Anthony Kramers , in an analysis of the formation of polymers, pointed out that such a chain reaction need not start with a molecule excited by light, but could also start with two molecules colliding violently due to thermal energy as previously proposed for initiation of chemical reactions by van' t Hoff. Wikimedia Commons has media related to Chain reactions. The initial conditions are critical, as the quantity of fissionable material must exceed the critical masswhich is the mimimum mass needed of fissionable material. I just wish it was clear that more pieces bus parking spiele needed to complete some of the set-ups. Some chain reactions have complex rate equations with fractional order or mixed order kinetics.

Proper conditions for a chain reaction depend not only on various external factors, such as temperature, but also on the quantity and shape of the substance undergoing the reaction.

Demonstration of a self-sustaining nuclear chain reaction was accomplished by Enrico Fermi and others, in the successful operation of Chicago Pile-1 , the first artificial nuclear reactor, in late In order to sustain a chain reaction, a sample must be large enough to slow the neutrons so that one can be captured by another nucleus and produce a second fission. Your current work will be lost. The main types of steps in chain reaction are of the following types.

The result is in fact an exponential growth, thus giving rise to explosive increases in reaction rates, and indeed to chemical explosions themselves.

A quantitative chain chemical reaction theory was created by Soviet physicist Nikolay Semyonov in The initial conditions are chain ractions, as the quantity of fissionable material must exceed the critical masswhich is the mimimum mass needed of fissionable material.

A line of turm spiele online falling after the first one has been pushed is an example of a spiel 1 chain reaction; a pile of wood burning after it has been kindled is an example of a chemical chain reaction. The extremely high temperature of the resulting plasma cracks the surrounding gas molecules and the free ions recombine to create new chemical compounds. This would in theory produce a chain reaction at the level of the nucleus.
