What is dissociated in chemistry?
dissociation, in chemistry, the breaking up of a compound into simpler constituents that are usually capable of recombining under other conditions. Most dissociating substances produce ions by chemical combination with the solvent.
What is dissociation process?
Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner, as do CO2 and H2O at high temperatures. Dissociation is the opposite of association and recombination.
What does the word dissociates mean?
transitive verb. 1 : to separate from association or union with another attempts to dissociate herself from her past. 2 : disunite specifically : to subject to chemical dissociation.
Does water dissociate gasoline?
Typically, gasoline contains more than 150 chemicals including small amounts of benzene, toluene, xylene, and sometimes lead. Gasoline may be present in the air, groundwater, and soil. Gasoline does not dissolve readily in water. However, some of the chemicals that make up gasoline can dissolve easily in water.
Do gases dissociate?
As for the question you supposedly intended to ask: no, electrolytic dissociation of dissolved substances never happens in gases the way it happens in water.
Why do ions dissociate?
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process represents a physical change known as dissociation.
What is dissociative reaction?
n. A psychological reaction characterized by such behavior as amnesia, fugues, sleepwalking, and dream states.
What is dissociative Behaviour?
Dissociative disorders are mental disorders that involve experiencing a disconnection and lack of continuity between thoughts, memories, surroundings, actions and identity. People with dissociative disorders escape reality in ways that are involuntary and unhealthy and cause problems with functioning in everyday life.
What is dissociation in simple words?
Dissociation is a disconnection between a person’s memories, feelings, behaviors, perceptions, and/or sense of self. 1 This disconnection is automatic and completely out of the person’s control. It’s often described as an “out of body” experience.
What is the polarity of gasoline?
Ethyl alcohol will dissolve in water in all proportions, because the polar molecules interact with each other freely. In contrast, gasoline (C8H18) is a completely nonpolar molecule. Water added to gasoline will not interact favorably with it.
What kind of gas is a dissociated atmosphere?
Forming gas. Forming gas is a mixture of hydrogen (mole fraction varies) and nitrogen. It is sometimes called a “dissociated ammonia atmosphere” due to the reaction which generates it:
When is associated gas called non associated gas?
When the associated gas can exist separate from oil in the formation it is called free gas. In opposite way the natural gas coming from gas and condensate wells, in which there is little or no crude oil, is named non-associated gas.
How is the degree of dissociation in a gas determined?
The degree of dissociation in gases is denoted by the symbol α where α refers to the percentage of gas molecules which dissociate. Various relationships between K p and α exist depending on the stoichiometry of the equation.
Why is dissociated ammonia used as an atmosphere?
It is sometimes called a “dissociated ammonia atmosphere” due to the reaction which generates it: 2 NH 3 → 3 H 2 + N 2 It can also be manufactured by thermal cracking of ammonia, in an ammonia cracker or forming gas generator. Forming gas is used as an atmosphere for processes that need the properties of hydrogen gas.
