Reactions of acids are often generalized in the form HA H < sup >+</ sup > + A < sup >−</ sup >, where HA represents the acid and A < sup >−</ sup > is the conjugate base.

Reactions such as + → + ( the two-photon annihilation of an electron-positron pair ) are an example.

Reactions with chalcogens are highly exothermic ( release energy ); the reaction with oxygen or air occurs at room temperature, and therefore barium is stored under oil or inert gas atmosphere.

Reactions with other nonmetals, such as carbon, nitrogen, phosphorus, silicon, and hydrogen, are generally exothermic and proceed upon heating.

Reactions with water and alcohols are also very exothermic and release hydrogen gas:

Reactions can proceed by themselves if they are exergonic, that is if they release energy.

Reactions that take place at Down's cell are the following:

Reactions are slow at room temperature, but are vigorous above 200 ° C:

Reactions of these isotopes of hydrogen are of interest because the energy per unit mass of fuel released by their fusion is much larger than that from fission of heavy nuclei.

Reactions in which such electron exchange occurs ( which are the basis for batteries ) are called reduction-oxidation reactions or redox reactions.

SomeOrganic Reactions chapters are made into dedicated books, such as this chapter on the Stille reaction by Farina et al.

The books are published by John Wiley and Sons, Inc. who also manage and maintain the Organic Reactions website.

Experimental approaches for characterizing polymers are also common, using Polymer characterization methods, such as size exclusion chromatography, Viscometry, Dynamic light scattering, and Automatic Continuous Online Monitoring of Polymerization Reactions ( ACOMP ) for determining the chemical, physical, and material properties of polymers.

Reactions 1 and 3 are very rapid compared to the second, so it is the slowest reaction that is reflected in the rate equation.

Reactions are catalyzed by a type III PKS enzyme.

They are divided into Noon actions ( playable on their own ), Shootout actions ( played during a shootout ), and Reactions ( played in response to another action ).

Reactions occurring at the counter electrode surface are unimportant as long as it continues to conduct current well.

Reactions are known where the deuterated species reacts faster than the undeuterated analogue, and these cases are said to exhibit inverse kinetic isotope effects ( IKIE ).

Reactions are driven to completion by the use of excess ( two-to four-fold ) activated amino acid.

Reactions to chemical components of the diet are more common than true food allergies.

Reactions secondary to food ingestion are defined generally as ' adverse reactions to food '.

" Psychotic Reactions and Carburetor Dung " was a 1971 essay by Lester Bangs, later collected in a book of the same name ( ISBN 0-679-72045-6 ).

Reactions to the ruling were mixed, with some gay-rights groups condemning the ruling as not legally recognizing sex between people of the same gender.

* Allergic Reactions / Hypersensitivity: Occasionally isolated urticaria without other symptoms, isolated cases of anaphylaxis involving urticaria, angioedema, asthma, and rapid fall in blood pressure.

Reactions take place at both electrode surfaces, absorbing each ion.

Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism.

Reactions can be exothermic, where ΔH is negative and energy is released.

Reactions can also be characterized by the internal energy which takes into account changes in the entropy, volume and chemical potential.

Reactions can take place between two solids.

Reactions studied by the CRESU technique typically have no significant activation energy barrier.

According to chemistry historian Henry Leicester, the influential 1923 textbook Thermodynamics and the Free Energy of Chemical Reactions by Gilbert N. Lewis and Merle Randall led to the replacement of the term " affinity " by the term " free energy " in much of the English-speaking world.

* Hermann Schmalzried: Solid State Reactions.

Reactions to the appearance of feminists among fannish ranks led indirectly to the creation of A Women's APA and WisCon.

This reaction was reportedly first studied in 1978 by the team at the Flerov Laboratory of Nuclear Reactions ( FLNR ) under the leadership of Yuri Oganessian.

Reactions to these chemicals include sweating, tingling and sore mouth or throat ; swelling of the lips, tongue and face ; rash ; vomiting and abdominal pain, heartburn ; and, in the most severe cases, breathing difficulties, wheezing and collapse.

Atomic Reactions.

It was first correctly identified in 1966 by scientists at the Flerov Laboratory of Nuclear Reactions in Dubna, Soviet Union.

Following initial work between 1958 – 1964, in 1966, a team at the Flerov Laboratory of Nuclear Reactions ( FLNR ) reported that they had been able to detect < sup > 250 </ sup > Fm from the decay of a parent nucleus (< sup > 254 </ sup > No ) with a half-life of ~ 50s, in contradiction to the Berkeley claim.

Reactions from Puerto Rico's two major political parties were mixed.

Reactions of governments in all developed and developing countries against the economic slowdown were largely inspired by keynesian economics.

Reactions that take place on polar stratospheric clouds ( PSCs ) play an important role in enhancing ozone depletion.
