A fission reaction is a chemical reaction wherein the atom gets split to generate energy. The most commonly used controlled form of this is in splitting Hydrogen for producing energy in nuclear reactors. It is also used in weaponry such as Hydrogen Bombs which have much greater power than in nuclear fusion reactions.
It is not a chemical reaction! You can write U-235, with atomic number 92, plus a neutron, produces two fission product nuclei (which can be various combinations) plus two or three free neutrons. The limitations of notation on this site does not allow to show this properly. If you look up nuclear fission in Wikipedia you will see how such a reaction is written.
Fission does not respond to changes in temperature and pressure like chemical reactions do. In a nuclear reactor, the fission chain reaction can be sped up by removing rods of cadmium, which absorb neutrons. These are in place to prevent the reaction from occurring too quickly. Remove them, and the chain reaction may proceed out of control.
Basically a chain reaction (nuclear or chemical) is a self sustaining auto-catalytic reaction.In a nuclear reactor it is a neutron chain reaction, where each neutron released in every fission event can trigger another fission event. In a nuclear reactor the excess neutrons must be disposed of, which is the purpose of the control rods so that the reaction can be kept at some desired constant rate.
no
yes.
Bond fission is the breaking of bonds in a chemical reaction. (Organic Chemistry)

Thebond energy in an atomic nucleus are greater than the energy of chemical bonds.The binding enegy of a nucleon is 7,6 MeV.
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
To sustain a fission chain reaction, each fission reaction must result in one more fission reaction. And that one should result in one more, and so on.

another name for nuclear fission is: E=MC squared
The first time a fission chain reaction was produced was in 1942
what is the role of control rods in a fission reaction
I would say it is actually both. Fusion itself is a chemical reaction but it is powered by a physical feature named gravity.
