Dissociation is the process by which ions separate when an ionic solid dissolves in a solvent. The compound is simply broken down into its elements when reacted with a solvent.
For example, if you have the compound AB, it could be broken down into A + B
AB ----> A + B
You could also take the example of dinitrogen tetroxide (N2O4) dissociating to nitrogen dioxide (NO2)
N2O4 ----> 2 NO2
which is the same as writing
N2O4 ----> NO2 + NO2
so you can see how N2O4 was broken down into smaller parts

∙ 13y agoDissociation is the process by which a molecule separates into ions. It may also be called ionization, but because there are other ways to form ions, the term dissociation is preferred. Substances dissociate to different degrees, ranging from substances that dissociate very slightly, such as water, to those that dissociate almost completely, such as strong acids and bases. The extent to which a substance dissociates is directly related to its ability to conduct an electric current. A substance that dissociates only slightly (as in the case of a weak acid like vinegar) is a weak electrolyte, as it conducts electricity poorly. A substance that is almost completely dissociated (such as table salt, NaCl, or hydrochloric acid, HCl) conducts electricity very well. The ability to conduct electricity is based on the ionic makeup of a substance. The more ions a substance contains, the better it will conduct electricity.

That is, degree of dissociation = (Number of molecules or moles ionized / Total Number of molecules or moles taken).
It is also called Degree of ionization.

Molecular weight of air at standard conditions?
First, molecular weight is a direct function of the level of dissociation and hence an indirect function of temperature. Dissociated Air has a significantly (about an order or magnitude) lower molecular weight as associated air (e.g. air at room temperature). Dissociation for air starts somewhere around 2000 Celsius (that's where O2 goes into O+O) and hence, the molecular weight of air up to 2000 Celsius is constant. This also affects the "specific gas constant" which drastically decreases in temperature regimes where dissociation occurs.With that said, the molecular weight of DRY air (no water vapor) is 28.97. Engineering Toolbox does a good job of breaking down the composition of associated air, see the URL below:http://www.engineeringtoolbox.com/molecular-mass-air-d_679.html
How molecular ion is formed?
when an atom loses or gain an electron, it form an ion. similarly, a molecule may also lose or gain an electron to form a molecular ion. example., CH4+
Why does a larger Ka mean a stronger acid?
A larger Ka indicates that the acid will more readily react as the molecular bonds are relatively weak. The Ka is known as the dissociation constant.
What is compound dissociation?
Dissociation is the decomposition of a substance in ions in a solution.Generally is a decomposition.
What is the dissociation constant k of pure water?
The dissociation constant of pure water is 1.9E-5.

What is energy contained in molecular bonds?
Based on the question, my answer is "bond energy." I doubt that we need to step too far into chemistry and cover bond-dissociation energy (or BDE).

Is the dissociation disorder healthy?
Dissociation is a dangerous mental disease.
Is Dissociation a process?
Dissociation is a process that occurs along a spectrum of severity
What is compound dissociation?
Dissociation is the decomposition of a substance in ions in a solution.Generally is a decomposition.
Is Bond dissociation energy positive or negative?
The dissociation of a compound is when a molecular compound, for example: HCl(g) is broken apart to give H+ and Cl- ions when it is dissolved in water. Example the dissociation of compound HCl(g): HCl(g) --(H2O)--> H+ (aq) + Cl-(aq)
