Inorganic chemistry is the branch of chemistry concerned with the properties and reactions of inorganic compounds.
Inorganic chemistry is based upon physical chemistry and forms the basis for mineralogy and materials chemistry.
The range of inorganic chemistry includes both molecular compounds, which exist as discrete molecules, and crystals, whose structures are described by infinite lattices of regularly-ordered atoms and which are studied by crystallography and solid-state chemistry.

Chemical Reaction, process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of substances.
An example of a chemical reaction is formation of rust (iron oxide), which is produced when oxygen in the air reacts with iron.
In order to discuss the nature of chemical reactions, certain basic facts about chemical symbols, nomenclature, and the writing of formulas must first be understood.

Chemicals are an essential component of manufacturing, vital to industries such as construction, motor vehicles, paper, electronics, transportation, agriculture, and pharmaceuticals.
Chemical manufacturing is divided into six segments: Basic chemicals; synthetic materials, including resin, synthetic rubber, and artificial and synthetic fibers and filaments; agricultural chemicals, including pesticides, fertilizer, and other agricultural chemicals; paint, coating, and adhesives; cleaning preparations, including soap, cleaning compounds, and toilet preparations; and other chemical products.
Chemical firms in the United States are concentrated in areas abundant with other manufacturing businesses, such as the Great Lakes region near the automotive industry, or the West Coast near the electronics industry.

 chemical reaction
A chemical reaction does not change the nucleus of the atom in any way, only the interaction of the electron clouds of the involved atoms.
A chemical reaction almost always involves a change in energy, conveniently measured in terms of heat.
A reaction may have a positive ΔH. This means that, to proceed, the reaction requires an input of energy from outside.

 Chemical Reactivity
Useful information about reaction mechanisms may be obtained by studying the manner in which the rate of a reaction changes as the concentrations of the reactant and reagents are varied.
A reaction mechanism should include a representation of plausible electron reorganization, as well as the identification of any intermediate species that may be formed as the reaction progresses.
Since chemical reactions involve the breaking and making of bonds, a consideration of the movement of bonding (and non-bonding) valence shell electrons is essential to this understanding.

 Simultaneous particle separation and chemical reaction - US Patent 6221677   (Site not responding. Last check: 2007-10-15)
It includes chemical reaction, physical binding, adsorption, absorption (for example when the analyte particle is sucked inside a porous reagent particle such as a zeolite), antibody reaction, nucleic acid binding, ion pairing, ion exchange, chromatographic type reaction and receptor hormone reaction.
The length of the reaction channels and the distance traveled by the product stream prior to detection can be selected to allow reactions to go to completion, to limit the sampling of constituents based on their diffusion constants, and to alter the efficiency of separation of particles.
The reaction channel is long enough to permit small analyte particles to diffuse from the sample stream and have a detectable effect on reagent particles, preferably at least about 2 mm long.

 Condensation reaction - free-definition   (Site not responding. Last check: 2007-10-15)
A condensation reaction (also known as a dehydration reaction) is a chemical reaction in which two molecules or moieties react with each other with the concurrent loss of water or ammonia.
It may be considered as the opposite of a hydrolysis reaction, ie, the cleavage of a chemical entity into two parts by the action of water.
This type of reaction is used as a basis for the making of many important polymers for example: nylon, polyester and various epoxies.

 APPLICATIONS OF PARALLEL REACTION
Running a chemical reaction in the same place and at the same time with some physical process of separation in the resultant reaction zone is an effective way to increase chemical processing rates.
Then in the reactive-separation zone not only the reaction heat will cause additional mass transfer between vapor and liquid phases but it will be increase a rate of the chemical process.
The reason is that removal of reaction products as they form promotes reversible processes in accordance with Le Chatelier principle, and irreversible processes in accordance with the law of mass action, because reagent concentrations in the reaction zone are increased as the products are removed.

To save the laser energy, we adopted the combustion synthesis which is the exothermic reaction between the raw materials.
By adding chemical reaction heat to laser heat, the particles of the products of the reaction were bonded together by relatively low laser energy.
By mixing the powdered binder with the reactive raw materials, the simple layered models were fabricated Since burning in the furnace is unnecessary in the proposed method, it is possible to fabricate the models in a short time.

Inorganic chemistry is the branch of chemistry concerned with the study of materials that contain any combination of chemical elements except for organic compounds.
Inorganic chemistry often overlaps with mineralogy, geochemistry,analytical chemistry, environmental chemistry, physical chemistry, and Organometallic chemistry.
Organometallic chemistry combines of organic chemistry with inorganic chemistry, and is partially characterized by the study of metal-carbon bonds, in which the carbon, apart from the metal-carbon bond, would otherwise be considered a part of an organic compound.

This is an addition reaction in which an atom or group of atoms is inserted between two atoms initially bound together.
The product of such a reaction is called a “polymer”, and the starting material the corresponding “monomer” (Greek polus, much; meros, share; monos, alone).
The term polymerization is also used for processes in which a polymer is formed, not from the monomer, but from other reactants of low molecular mass.
