Depending on the total mass of uranium and the enrichment, geometry, purity, etc.

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.
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.
Which of the following elements is most likely to be produced during a nuclear fusion reaction helium-4 hydrogen-1 uranium-235 or uranium-238?
Helium-4 can be a product of fusion. Hydrogen-1 cannot be produced by fusion. The uranium isotopes were probably produced by fusion in some star, long ago, and possibly not as uranium, but as something that decayed into uranium. I suppose it would be possible to produce the uranium isotopes in a lab by fusion, but I cannot imagine anyone do so, unless it was to prove a point.
What isotope uranium is radioactive?
Yes.......most likely. I can't think of anything to do with Uranium, that isn't radioactive! -------- Uranium natural isotopes are not so radioactive compared with other isotopes; but all the isotopes of uranium are radioactive.
What element is best suited for nuclear fission?
Plutonium, most likely, a man-made element, but mined Uranium will also do.

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.
What was the function of graphite in the first atomic reaction?
moderator, it slowed fast neutrons to thermal velocities so that they would be less likely to be captured by uranium-238 before they could fission uranium-235.

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.
What element is most likely to be produced as a result of a fission reaction using uranium-235 as a fuel?
There are about 50 that form, the 2 groups most likely are ones with Atomic Mass numbers near 95 and 140.
If a piece of uranium is flattened into a pancake shape will this make a supercritical chain reaction more or less likely?
It would make a chain reaction less likely. A high density is needed to maintain a chain reaction. The flat pancake does not have the right shape as neutrons will be able to pass through with only a very low probability of hitting a nucleus.

Is uranium more likely to lose or gain electrons?
Uranium loose electrons becoming a cation.
What material used to decrease the rate of reaction is?
Water for one. If a reaction is diluted, the components of the reaction are less likely to contact one another. This will mean that they will be also less likely to continue a reaction.
What are the dangers associated with uranium ming?
The radon gas emitted by the uranium ore makes it much more likely that you'll get cancer if you're exposed to it for too long.
