Which will leak more neutrons two separate pieces of uranium or the same pieces stuck together?

The pieces stuck together. This is because there will be more of a chain reaction, so there will be more neutrons available to leak in the first place.

The stronger force between protons and neutrons in a small nucleus and a larger nucleus?
In a small nucleus, such as oxygen, xenon, or any of the lighter elements, the strong force generated by the protons and neutrons is stronger than the repulsion between protons, and the nucleus holds together. In a larger nucleus, such as uranium, curium, or the heavier elements, the strong force isn't strong enough to hold it together, and the electromagnetic force pulls it to pieces.
How does nuclear energy develops nuclear weapon?
To produce nuclear energy an unstable element, such as Uranium 235, is struck with neutrons which causes it to decay and release more neutrons and a small amount of mass changes into energy, E=MC2. This is know as nuclear fission. The neutrons continue on and strike more atoms of Uranium causing them to decay. In the reactor are rods of Boron which absorb stray neutrons and can be either withdrawn or inserted to control the rate of the reaction. The energy released is mostly heat and is used to heat water to steam, which is then used to turn turbine generators and send power to the grid. In a nuclear weapon there is a large enough amount of the unstable element to cause what is called, "Critical mass", that is, enough for the nuclear reaction to start all by itself. It is broken into two pieces so that, until explosives slam the two pieces together, the reaction will not start. Once the pieces have collided and critical mass has been achieved, there are no Boron rods to control the reaction so, there is a run away chain reaction and all the fissionable material decays, releasing its energy.
What is fission made from?
Nuclear fission occurs in a few elements and then only in certain isotopes, best known are uranium-235 and plutonium-239. In these cases capture of a neutron causes the nucleus to split up into two lighter pieces, and for neutrons to be emitted. This enables a chain reaction to be started.
Is uranium reliable?
It is unclear what you are asking. "Reliable" in what way? The halflife of each uranium isotope is absolutely reliable and because of that is used for radiometric dating. Uranium-235 fissions very reliably when struck by neutrons making the neutron chain reaction happen and powering both nuclear power plants and some nuclear explosives. Uranium-238 makes excellent armor penetrating bullets that not only reliably penetrate thick armor but once inside absolutely reliably spontaneously burst into flame, spraying the occupants of the vehicle with burning pieces of molten metal. Thus delivering a kill of both vehicle and crew with nearly unbelievable reliability. However although uranium makes a beautiful orange pottery glaze such pottery should never be used for food or water as the uranium can leach and when ingested sometimes causes cancer decades later. Uranium has many other properties.
What are the Function of each parts of nuclear power plant?
ReactorA diagram of a fission reaction The reactor is where the reaction takes place. Nuclear reactors use nuclear fission, which breaks the nucleus of a uranium atom into smaller pieces, freeing neutrons in the process. The freed neutrons break other nuclei into smaller pieces, which free further neutrons. The movement of the neutrons generates heat.Control RodsControl rods are made of a substance, such as graphite or cadmium, that absorbs extra neutrons. Since the movement of the neutrons causes the reaction, absorbing the extra neutrons slows down the reaction.Steam GeneratorThe heat from the nuclear reaction is used to heat massive amounts of water in the steam generator. Inside the steam generator are bundles of tubes that keep the water from boiling, allowing it to superheat.Turbines and GeneratorThe superheated water from the steam generator turns turbines. The turbines then operate the generator, which creates the electricity.Cooling TowerThe best-known, and most-visible, part of a nuclear power plant is the cooling tower. In the cooling tower, water is cooled down to be used again.
Is a chain reaction more likely in two separate pieces of uranium or in the same pieces stuck together?
separate ------- Depending on the total mass of uranium, purity of uranium, physical form, enrichment, geometry, etc.
Is a chain reaction more likely to occur in two separate pieces of uranium-235 or in the same two pieces stuck together?
Stuck together.
Is a chain reaction more likely in two separate pieces of uranium or in the 2 combined?
Depending on the total mass of uranium and the enrichment, geometry, purity, etc.

What is that thing called where it has an image on itBreak it into pieces the whole picture can be seen on each of the separate pieces and if you put it back together it forms the original pic?

Why is a chain reaction more likely in a big pieces of uranium than its in a small piece?
A small piece has more surface area compared to its mass; as a result, more neutrons will escape before they can participate in the chain reaction.
How do you make nuclear weapons?
Some heavy elements such as uranium and plutonium disintegrate over time into lighter elements while ejecting neutrons and creating energy. These neutrons, not having an electric charge, can impact the nuclei of other atoms, causing them to disintegrate immediately. Normally this is the end of the process, because most neutrons produced by this process pass harmlessly into space, without impacting other atoms of the uranium or plutonium. Increasing the size of the piece increases the number of target nuclei available to the neutrons, so that more neutrons impact a nucleus. A critical mass is formed when a piece of uranium or plutonium is just the right size to maintain a chain reaction, continually producing enough neutrons to maintain the process indefinitely. A nuclear reactor has exactly the amount of uranium or plutonium, at just the right proximity and moderated by heavy water, so that an average of one neutron is produced by each neutron already produced - resulting in a chain reaction. A nuclear explosion will occur if there is more nuclear fuel than a critical mass, so that the number of available neutrons grows exponentially. A nuclear weapon has sufficient nuclear fuel for an explosion to occur, in two or more separate pieces, each of sub-critical size and separated from each other. A trigger mechanism fires the pieces together so that they rapidly form a super-critical mass, and the energy released results in the explosion. A thermonuclear weapon uses a nuclear weapon as the trigger for an explosive fusion of hydrogen atoms. When heated to extreme temperatures by a nuclear reaction, atoms of hydrogen will fuse into heavier atoms, producing energy.
What are three pieces of atoms?
Electrons, protons, and neutrons:)
When pennies are put together are they two separate pieces?
No. A US cent minted after 1983 starts out life as a zinc disk that is then "upset"

How you separate separate aluminium pieces from salt?
One commonly used method to separate aluminium pieces from salt is by using a magnet. Since aluminium is not magnetic, the magnet can attract and separate the aluminium pieces from the salt. Another method is to dissolve the salt in water and then use filtration to separate the larger aluminium pieces from the saltwater solution.
