What are Zeolites?
admin Zeolites are aluminosilicates i.e. three dimensional net work silicates in which some silicon atoms are replaced by aluminium atoms. They are found in nature as well as synthesized in the…

What do you mean by enzymes as catalyst?
All biological reactions are catalyzed by special catalyst called enzymes. Thus enzymes are defined as biological catalyst. Chemically all enzymes are globular proteins. However, some enzymes are also associated with…
What is the other type of fissionable material which can be used in nuclear fission processes?
Various type of radioactive material like plutonium can be used as a fissionable material. However, ordinary uranium consists only of about 0.7 percent of U235 and it is extremely difficult…
Why is 92U238 not suitable for chain reaction?
As we know 92U238 is bigger in size so it will not breakup unless the energy of bombarding neutrons is more than 1.2 MeV. Such neutrons are called fast neutrons.…
What is Nuclear Fusion?
It is a process of formation of heavier and bigger nucleus by the combination of various lighter and smaller nucleus. This process is called nuclear fusion. This process can take…
How energy is produced in the sun and the stars?
The energy production in the sun and the star could be explained on the basis of carbon cycle by means of which hydrogen is converted into helium. 6C12 act as…
What is Hydrogen Bomb?
The thermal nuclear reactions among nuclei of hydrogen isotopes like deuterium and tritium serve as sources of energy on earth crust. These type of nuclei occur more rapidly so they…
Which is more powerful: hydrogen bomb or atom bomb?
Hydrogen bomb is more powerful than atom bomb due to the fast freeze of very large amount of energy in the thermo nuclear reactions among the nuclei of hydrogen isotopes.…
What are Nuclear Reactions?
A nuclear reaction involves the splitting of nuclei, usually producing something unstable and releasing neutrons. After a nuclear reaction, a process of emitting radiation (alpha beta and gamma) occurs for…
What is the difference between nuclear reaction and chemical reaction?
Difference between Nuclear reaction and Chemical reactions are as follows: NUCLEAR REACTION CHEMICAL REACTION Nuclear reaction takes place in the atom’s nucleus. Electrons in the atom are responsible for chemical…
