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.
A new chemical substance is formed during a chemical reaction by rearranging the atoms of the reactants. The products of a chemical reaction have different properties compared to the original reactants.

The amount of energy released from a fission reaction is much greater than that from a chemical reaction because fission involves the splitting of atomic nuclei, leading to a significant release of nuclear binding energy. This energy release is millions of times greater than the energy released in chemical reactions, which involve breaking and forming chemical bonds.
Bond fission is a chemical process in which a chemical bond in a molecule is broken, resulting in the formation of two separate ions, radicals, or new molecules. This process can be induced by various means such as heat, light, or chemical interactions.
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.
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
The first time a fission chain reaction was produced was in 1942
In a chain reaction, each fission reaction must produce at least one additional fission reaction to sustain the reaction. This is necessary to achieve a self-sustaining nuclear reaction where each fission event leads to more fission events, releasing energy in the process. Without this multiplication of fission reactions, the chain reaction would not be able to continue and sustain itself.
No. Fireworks rely on chemical rather than nuclear energy. They are driven by an oxidation-reduction reaction. Fireworks were developed centuries before we discovered nuclear fission.
Only with fission (see nuclear science).
fission..sup
For a chain reaction to occur, each fission must produce at least one more fission reaction. This leads to a self-sustaining reaction where each fission event triggers more fission events, resulting in a continuous release of energy.
Generally no. Unless the chemical reaction involves nuclear fission or fusion, you can only rearrange existing components; you cannot create new atoms.
