How many neutrons are produced during a typical uranium fission reaction and what is the role of these neutrons in a nuclear chain reaction?
A typical uranium fission event produces 2 to 3 neutrons. These neutrons are moderated (slowed down) and go on to initiate the fission of more uranium. On average, in a controlled reaction that is maintained at normal criticality (KEffective = 1), each fission creates exactly one neutron that is used to produce another fission.
An ongoing series of fission reactions is called a (n) .?
Fission and fusion reactions are chain reactions but in different ways. In fission reaction a heavy nuclei is bombarded with a slow moving neutron and this nuclei breaks to produce more such neurons along with generation of new elements. These slow moving neutrons are further used to carry out fission of more such nuclei. This is chain reaction. Fusion reaction are a different class of nuclear reaction in which small nuclei fuse together to produce bigger nuclei along with the generation of energy due to mass defect.. In fusion reaction lot of energy is produced and this energy is used to carry out further reaction. Thus both can be called series reaction.
How is a chain reactor controlled?
Since the continued chain reaction of a nuclear fission reactor depends upon at least one neutron from each fission being absorbed by another fissionable nucleus, the reaction can be controlled by using control rods of material which absorbs neutrons. Cadmium and boron are strong neutron absorbers and are the most common materials used in control rods. A typical neutron absorption reaction in boron is In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by- products which absorb neutrons build up. To keep the chain reaction going, the control rods must be withdrawn further. At some point, the chain reaction cannot be maintained and the fuel must be replenished
Is atomic bomb and nuclear bomb the same?
No, I don't believe so anyway. You see, an Atomic Bomb has an explosion made of the ripping of atoms whereas a nuclear bomb is either a Fission or Fusion reaction(fission=the splitting of molecules/fusion=the joining of atoms to create molecules)Ex. The sun is a giant nuclear explosion/reaction when the atoms of Uranium molecules separate to make a fission reaction and those same atoms join with other atoms to make a fusion reaction and recreating molecules to procede to the fission stage where the process is redone again and again and... etc.Fun Fact: Only two atomic bombs have been dropped one on Hiroshima and one on Nagasaki No nuclear bombs have ever been dropped in war.-Zazzer acc;)The above is one of the most confused explanations/understandings I have ever seen. For one thing "ripping of atoms" is confused, it really is just a way of saying fission yet its use implies something different from and probably weaker than fission is happening. Molecules are not involved here either, only atomic nuclei (this is a serious confounding of chemical reactions and nuclear reactions, which happen in entirely different parts of atoms and involve about three orders of magnitude difference in energy). Another thing the reaction in the sun does not involve uranium, the sun (as any star) only operates on fusion and at its current stage of life can only fuse hydrogen into helium. There is no such thing as a fission-fusion... and repeat cycle in any star. No star can ever produce elements large enough and heavy enough to fission, only supernova explosions are powerful enough to do that. The two Fission bombs dropped on Japan in the war could equally validly be called Atomic bombs or Nuclear bombs.Atomic and Nuclear are basically interchangeable terms in this area. Both refer to energy obtained from the binding energy of atomic nuclei.There are two types of reactions involved:Fission - breaking of large heavy atomic nuclei into smaller lighter ones.Fusion - combining of small light atomic nuclei into larger heavier ones.From the 1945 Trinity test through 1951 all atomic/nuclear bombs were Fission bombs. After the 1952 Ivy Mike test, atomic/nuclear bombs could be Fusion bombs. However a Fusion bomb is very complex, needing at minimum:A Fission bomb trigger stage to generate x-rays to drive the implosion of the Fusion stage.A rod shaped Fission bomb "sparkplug" the length of the Fusion stage to ignite fusion at maximum compression of the Fusion stage.A cylindrical Fusion bomb stage.A cylindrical metal tamper around the bomb to hold it together for a few extra microseconds, to keep the reaction going and get a good yield. (Note: this tamper is usually made of depleted uranium because of its high density. however a depleted uranium tamper is able to absorb the high energy fusion neutrons and fission, making it responsible for about 90% of the yield and fallout of such bombs.)Therefor a typical Fusion bomb is really a fission-fission-fusion-fission bomb.Most modern Fusion bombs improve the efficiency of and miniaturize the fission trigger by using a hollow core deuterium/tritium gas fusion booster design. A Fusion bomb designed this way is really a fission/fusion-fission-fusion-fission bomb.All currently operating atomic/nuclear reactors are Fission reactors. Work has been going on since the early 1950s to make a Fusion reactor (as it should be cleaner and its fuel is more available), but none has reached "breakeven" (ability to generate enough energy to operate itself) let alone generate enough excess energy to operate as a powerplant.BTW, the "Fun Fact" is also completely false and confused. Many many atomic bombs have been dropped from airplanes or fired as missile warheads, beginning in 1945 and ending in either 1961 or 1962. The two bombs dropped on Hiroshima and Nagasaki were thee only ones actually used in war.Please excuse my "micro-thesis" on the subject, but there were so many things needing correction and/or clarification.
What are the products of a reaction of a metal with an acid?
If the acid is hydrochloric acid, HCl, then the products are the metal chloride and hydrogen gas. For example, if magnesium is dropped in hydrochloric acid, the products will be aqueous magnesium chloride and hydrogen gas.

What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
How much energy is produced by a nuclear reactor?
For a typical fission reactor, power output can range from maybe 700 to 1000 MW (megawatts) with most modern deisgns being in the high end of that range.
What is the energy efficiency of a typical nuclear power plant?
The energy efficiency of a typical nuclear power plant varies, depending on its design, but a typical value might be around 33%.

What are the products of a reaction of a metal with an acid?
If the acid is hydrochloric acid, HCl, then the products are the metal chloride and hydrogen gas. For example, if magnesium is dropped in hydrochloric acid, the products will be aqueous magnesium chloride and hydrogen gas.
What is the rate of heat generation from fission of nuclear fuel?
These are approximate figures, but in the right ballpark. A typical large reactor will produce about 3000 MW thermal, and contain about 75 tonnes of fuel, so that means 40 MW/tonne. Or if you like, 40KW/Kg.
What would you expect from an endothermic reaction?
Endothermic reactions are characterized by the release of heat during the reaction. A typical example is the combustion of methane, which when combined with oxygen releases water and carbon dioxide.
How much power is produced during nuclear fusion?
To get an exact answer, you would have to specify a fusion reaction; different reactions will produce different amounts of energy. However, to get a rough idea, the energy produced is in the order of a million times more than the typical chemical reaction.
