The neutron
One of the particles released during the fission of uranium-235 is a neutron. When uranium-235 undergoes fission, it splits into two smaller atoms along with several neutrons. These neutrons can then go on to initiate additional fission reactions in a chain reaction.
Neutrons are required to start a fission reaction as they can initiate the splitting of uranium or plutonium atoms. In the process, additional neutrons are released which can go on to trigger more fission events. So, while neutrons are necessary to begin a fission reaction, they are not typically produced as a product of the reaction.
After the nuclear fission of uranium-235 many fission products (other elements) are formed.
Nuclear fission in a nuclear reactor is initiated by bombarding uranium or plutonium atoms with neutrons, causing them to split and release more neutrons, which then continue the chain reaction.
Probably approx. 40 kg of enriched uranium.
Probably you think at fission products.

Uranium-238 and Uranium-235 do not release neutrons spontaneously in nature in the same way they do during a fission process. Neutrons are typically required to initiate the fission process in nuclear reactions. In natural settings, radioactive decay processes such as alpha and beta decay occur in uranium isotopes, but not neutron release.
If a solid piece of uranium goes through a process like fission, the amount of uranium left would depend on the specific fission reactions that occur. During fission, uranium atoms split into smaller atoms, releasing energy and more neutrons which can continue the reaction. Some uranium atoms may be converted into other elements through the fission process, so the amount of remaining uranium would be less than the original piece.
The fission of uranium-235 is an example of natural radioactivity, as uranium-235 is a naturally occurring radioactive isotope. Artificial radioactivity, on the other hand, refers to the radioactivity induced in a normally stable element through processes like nuclear reactions or particle bombardment.
It is true that a uranium nucleus splits in the nuclear fission of uranium.
Neutrons are necessary to start a fission reaction. When a neutron collides with a heavy atomic nucleus, such as uranium-235, it can induce the nucleus to split and release more neutrons, leading to a chain reaction.
The fission energy of the fissile isotope uranium-235 is 1,68.10e8 kJ/mol.

Carbon dioxide is not a product of the fission of uranium. When uranium undergoes fission, it typically produces two or more fission fragments, such as krypton and barium isotopes, along with neutrons and a large amount of heat.

In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
