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

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 between ozone and onboard substances, including skin oils and cosmetics, can produce toxic chemicals as by-products.

Reactions can increase or decrease their rates with pressure, depending on the value of.

Reactions to and symptoms of trauma can be wide and varied, and differ in severity from person to person.

Reactions to ingestion of this plant can include both gastrointestinal and cardiac effects.

Reactions to poisonings from this plant can also affect the central nervous system.

* Reactions can be either photochemical or thermal.

* Reactions can be either ring-opening or ring-closing ( electrocyclization ).

Reactions with water produce hydrogen which can be explosive.

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

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

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

Reactions are considered to take place under thermodynamic reaction control when the reverse reaction is sufficiently rapid that the equilibrium establishes itself within the alloted reaction time.

Reactions between diols ( HO-R-OH ) and bis-ketenes ( O = C = CH-R '- CH = C = O ) yield polyesters with a repeat unit of (- O-R-O-CO-R '- CO -).

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

Reactions between the underside of the disc and a substance on the paper sleeve caused the fourth disc to be almost unplayable.

Reactions to the letter brought heightened tensions between the British Parliament and Massachusetts, and resulted in the military occupation of Boston by the British Army, which contributed to the coming of the American Revolution.

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.

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

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 ).

ADRAC publishes the Australian Adverse Drug Reactions Bulletin every two months. The Government's Quality Use of Medicines program is tasked with acting on this reporting to reduce and minimize the number of preventable adverse effects each year.

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 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 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.

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.
