The Empirical Formula is
<span>a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.</span>
Double replacement means a reaction that includes two molecules that each have two different ions. After the reaction, the ions pairs have switched, which is what is shown in the above equation.
A single replacement would be a very simple reactions such as:
2Fe(II)S + Ov2^2- -> 2Fe(II)O + 2S^2-
A decomposition reaction would be shown as this:
2NaCl -(dissolve in water)> 2Na^+ + Clv2^-
A synthesis reaction could be the exact opposite:
2Na^1+ + Clv2^1- -> 2NaCl
Answer:
Chain reaction
Explanation:
A chain reaction is a process by which neutrons that have been released in a first nuclear fission produce an additional fission in at least one more nucleus. This atomic nucleus fishes and releases more neutrons, giving the opportunity to repeat the process.
Nuclear fission is the physical-chemical reaction through which the nucleus of an atom is split. In the main interest of fission reactions is that through this operation a large amount of energy is obtained. According to the definition of nuclear energy, atomic energy is the energy contained in the nucleus of an atom and the energy obtained is thermal energy, energy in the form of heat.
The other form of exploitation is through nuclear fusion reactions. In this case, the process is reverse, merging two different nuclei forming a single atomic nucleus.
After fission of the atomic nucleus we obtain various fragments with a mass almost equal to half of the original mass plus two or three neutrons. It is remarkable the release of these two or three neutrons because they are what will allow a new reaction in another atom.

Answer:
Depending upon the mass gathered, the next process formation varies:
Nuclear fusion can kick in leading to formation of star. The nuclei fuse to together and energy is liberated in the form of light and heat.
If sufficient mass is not gathered to start nuclear fusion reaction, gaseous planet forms like Jupiter.
In third case, even though sufficient mass is present (twice the mass of Jupiter) still no fusion reaction starts. Such bodies are known as failed stars or brown dwarfs.
