In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium-235. What happens next?
a neutron is absorbed by an atom’s nucleus. (apex)
In a nuclear fission reaction a freely moving neutron is introduced to a nuclear fuel such as uranium what happens next?
If things go according to plan, the neutron encounters a fissionable atomic nucleus and then undergoes what is called neutron capture. That's the next step in the process. The presence of that neutron in the nucleus destabilizes the nucleus (more than it already is as that nucleus is radioactive and unstable anyway). In an extremely short period of time the instability results in nuclear fission. The nucleus splits.

The 235U fuel releases neutrons, which will continue the chain reaction. It also releases heat, which is carried off in the coolant and (usually) used to generate steam to spin turbines to generate electricity.
Where does technetium come from?
Technetium is now produced in nuclear reactors. Neutrons collide with atoms of uranium or plutonium to form new elements. The technetium is then converted to a compound called ammonium pertechnate (NH 4 TcO 4 ). That compound is then treated with hydrogen gas to obtain pure technetium metal.Technetium has never been found on Earth. It has, however, been found in certain types of stars.
What passes through the nuclear envelope?
Polar molecules, ions, proteins, and RNA can pass through the nuclear envelope. The smaller particles pass freely while the larger particles can only travel in one direction.

What is a fuel rod?
A nuclear fuel rod is a tube filled with nuclear fuel. The tube part is made of material that allows neutrons to pass freely through, so the fuel can undergo reaction unhindered. The rods are put together in groups called bundles, which are attached together so they can be handled together. There is a link below to the section in an article on nuclear fuel that explains the fuel rods. Pictures are there as well.
What would happen to entropy in a solid to gas reaction?
It increases; more freely moving particles.
How do you move when there is no gravity?
Very freely; Newton's law of action and reaction comes into full play.

Why is the nuclear test ban treaty important?
To be able to monitor unconditionally all nuclear tests. If nuclear tests are allowed freely, no third party would have rights to observe and provide expertise, no error reporting available, no standard recollection of facts, no responsibility recorded.
How is the DNA in prokaryotes different form the DNA in eukaryotes?
DNA in a eukaryote is surrounded by a nuclear membrane, hence forming a distinct nucleus whereas the DNA in a prokaryote is not bounded by a nuclear membrane and floats freely in the cytoplasm.
What passes through the nuclear envelope?
Polar molecules, ions, proteins, and RNA can pass through the nuclear envelope. The smaller particles pass freely while the larger particles can only travel in one direction.
Where are hereditary or genetic materials inside a Cell found?
They are located within the Chromosome: freely floating in Prokaryotes; contained within the nuclear envelope in Eukaryotes.
