what is a chain reaction?

Answer 1

the reaction which keep on going and products became reactants during the next reaction

Answer 2

Many reactions occur slowly at a given temperature. If they are exothermic reactions (giving off heat) any random reaction may provide enough heat to speed up a nearby reaction. Soon there is a chain (or string?) of reactions all producing enough heat energy to consume all the reactants. Logs burn in a fireplace because the heat of fire sustains a chain of reactions. Logs do not burn if cold even when surrounded with the same amount of fuel and oxygen, they slowly oxidize or rot. If someone slams on their brakes on a busy highway there can be a chain reaction (involving twenty or more cars?) initiated by a single car. Spontaneous combustion in a bunched up oily rag occurs because the heat of oxidation can not escape and builds up until there is a chain reaction.

Answer 3

A chain reaction is that reaction in which the end products of a reaction are same as the substances from it was started i.e. same as reactants and the reaction goes on and on

Answer 4

Chain reacion occured when a free radical formed in the reaction media, for example chlorination of methane clearify the chain reaction ,

Answer 5

A chain reaction is one "event" followed by another like a series of domino blocks putted close together. Put down one and you could have a million down minutes afterwards if you like. Johan

Answer 6

where on event creates a chain of events like in a nuclear reactor for example

Answer 7

Have u ever seen dominos set up so that one domino knocks over another dominoe and that one knocks over another one and that one knocks over another one, etc, etc, etc. That's a chain reaction.
