1. A heavy nucleus (U235 or Pu239), when bombarded by slow moving neutrons, split into two
or more nuclei.
2. Two or more neutrons are produced by fission of each nucleus.
3. Huge amount of energy is produced as a result of nuclear fission.
4. All the fission fragments are radioactive, giving off β and radiations.
<span>5. The atomic weights of fission products range from about </span>70 to 160.
6. The nuclear chain reactions can be controlled and maintained steadily by absorbing a
desired number of neutrons. This process is used in nuclear reactor.
<span>7. All the fission reactions are self-propagating chain-reactions because fission products contain </span>
neutrons (secondary neutrons) which further cause fission in other nuclei.
8. Every secondary neutron, released in the fission process, does not strike a nucleus, some
escape into air and hence a chain reaction cannot be maintained.
<span>9. The number of neutrons, resulting from a single fission, is known as the multiplication factor. </span>
When the multiplication factor is less than 1, a chain reaction does not take place.
<span>10. The control of chain reaction is necessary in order to maintain a steady reaction. This is </span>
carried out by absorbing a desired number of neutron by employing materials like
percentage of Cd, B or steel.
11. In a nuclear reactor, the multifactor is one. This is achieved by proper arrangement of
<span>fissionable materials.</span>

The finches that Darwin studied in the Galapagos islands have evolved with different types of beaks: drilling, cracking, tearing
zzz [600]
<span>The finches that Darwin studied in the Galapagos islands have evolved with different types of beaks: drilling, cracking, tearing, and fishing. This is an example of B. adaptive radiation.
These birds have adapted to their environment - they needed to drill, crack plants, fish, etc. so their beaks have changed and adapted so as to fulfill those needs.
Predation is used for hunting smaller animals, warning coloration refers to a change of color, and protective resemblance refers to an animal blending with its surroundings.

create visual representations that show the interactions between the particles in both samples during vaporization
ivolga24 [154]

Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.

<h3>What is vaporization?</h3>
  • Vaporization is the changing of a liquid into a gas.
  • This is known as a phase change.
  • This happens when the atoms receive enough heat energy.
  • The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
  • When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.

Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.

How many atoms are in KCI
vovikov84 [41]
<h3>Answer:</h3>

2 atoms

<h3>Explanation:</h3>
  • Compounds are substances that are formed when two or more elements chemically combine.
  • They are made up of molecules that contain different atoms from different elements.
  • For example, KCl is a compound that is made up of two atoms, one potassium atom and one chloride atom.
  • Unlike elements that are made of similar atoms, compounds contains atoms that are not similar from different elements.
