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 feedback leads to a self-amplifying chain of events.
Subsequently, how do you make a simple chain reaction?
Also question is, what is an example of a chain reaction?
A burning candle or other fire is an example of a chemical chain reaction. When a flammable material is surrounded by enough oxygen and is exposed to a source of heat or temperature above the flash point, a fire starts.
What three steps are involved in a chain reaction?
PCR is based on three simple steps required for any DNA synthesis reaction: (1) denaturation of the template into single strands; (2) annealing of primers to each original strand for new strand synthesis; and (3) extension of the new DNA strands from the primers.
Why is it considered as a chain reaction?
A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. … If each neutron releases two more neutrons, then the number of fissions doubles each generation.
