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 involved in the collodion processes are the same as those that apply other photographic processes.

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 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 '.

Each chapter of Organic Reactions is devoted to a particular organic chemical reaction, and chapters provide exhaustive coverage of literature work in the form of a tabular survey of known reactions.

Reactions whose rate depends only on the concentration of one reactant ( known as first-order reactions ) consequently follow exponential decay.

Reactions which are generally accepted to proceed by a radical mechanism are known however.

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

Reactions to Engel and Abington were widely negative, where many school districts and states have attempted to reestablish school-sponsored prayer in different forms since 1962.

Reactions of most infants that had already started developing object permanence were of frustration because they knew it existed, but didn't know where it was.

After the Nuclear Test Ban Treaty banned open-air nuclear testing, the tower was dismantled and despite its immense size moved from its original location to Jackass Flats in Area 25 of the Nevada Test Site, where it was used for Operation HENRE ( High Energy Neutron Reactions Experiment ), a series of radiation measurement experiments using a small linear accelerator to provide neutrons.

Reactions to less common species of fire ants.

Reactions to the extension between SR 125 and SR 67 were mixed, with reports of faster transportation through the East County area.

Reactions to children's faces: Resemblance affects males more than females.

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.

He called this ERA, for Electronic Reactions of Abrams, and introduced a number of different machines which he claimed were based on these principles.

Reactions also occur within these particles, and thus the term " solid support " better describes the insolubility of the polymer.

Reactions between aldimines and α-methylene carbonyls are also considered Mannich reactions because these imines form between amines and aldehydes.

Reactions of metal-pincer complexes are localized at three site perpendicular to the plane of the pincer ligand, although in some cases one arm is hemi-labile and an additional coordination site is generated transiently.

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

Reactions included INC President Sonia Gandhi who said his death was a great loss to the party.

Reactions to the song have been mixed, however: People magazine called the song " insipid " in its review of the album, and Allmusic said that Simpson was " trying way too hard to be sexy.

Reactions in which proton transfer is rate-determining exhibit general acid catalysis, for example diazonium coupling reactions.

The experiment began in June 2009 and, in January 2010, scientists at the Flerov Laboratory of Nuclear Reactions announced internally that they had succeeded in detecting the decay of a new element with Z = 117 via two decay chains of an odd-odd isotope ( undergoing 6 alpha decays before undergoing a spontaneous fission ) and of an odd-even one ( 3 alpha decays before fission ).
