In the second example CH < sub > 3 </ sub > COOH undergoes the same transformation, in this case donating a proton to ammonia ( NH < sub > 3 </ sub >), but cannot be described using the Arrhenius definition of an acid because the reaction does not produce hydronium.

However, this reaction cannot be reversed.

A primary cell is a special type of electrochemical cell in which the reaction cannot be reversed, and the identities of the anode and cathode are therefore fixed.

Each reaction is undergoing an equilibrium reaction between different oxidation states of the ions: when equilibrium is reached, the cell cannot provide further voltage.

The translation of nirodha as confinement means that this craving is a natural reaction, which cannot be totally escaped or ceased, but can be limited, which gives us freedom.

:" Although theoretical calculations can be made today, the eventually attainable range of chemical reaction cycles, error rates, speed of operation, and thermodynamic efficiencies of such bottom-up manufacturing systems cannot be reliably predicted at this time.

On the other hand, nuclear weapons are specifically engineered to produce a reaction that is so fast and intense it cannot be controlled after it has started.

* k < 1 ( subcriticality ): The system cannot sustain a chain reaction, and any beginning of a chain reaction dies out over time.

If the aldehyde cannot form an enolate ( e. g., benzaldehyde ), addition of strong base induces the Cannizzaro reaction.

Only 20 % of the power produced by the D-T reaction could be used this way ; the other 80 % is released in the form of neutrons which, because they cannot be directed by magnetic fields or solid walls, would be very difficult to use for thrust.

Even if a self-sustaining fusion reaction cannot be produced, it might be possible to use fusion to boost the efficiency of another propulsion system, such as a VASIMR engine.

" Rastafari's reaction to Selassie's ‘ death ’ was summed up by Bob Marley's song " Jah Live ", which declares emphatically that " God cannot die ".

For example, zinc cannot be solvated by hydrochloric acid, but it can be converted into the soluble salt zinc chloride by a chemical reaction.

Lone electrons normally cannot pass through the electrolyte ; instead, a chemical reaction occurs at the cathode consuming electrons from the anode.

It will burn well while wet and cannot be easily extinguished with water, although enough water will remove heat and may stop the reaction.

The embassy responded negatively in principle, adding that " US reaction to such a move cannot be determined in advance but would depend on circumstances at time ".

Under all definitions above, uranium-238 ( U-238 ) is fissionable, but because it cannot sustain a neutron chain reaction, it is not fissile.

Uranium's most common isotope, U-238, is fissionable but not fissile ( meaning that it cannot sustain a chain reaction by itself but can be made to fission, specifically by fast neutrons from a fusion reaction ).

It cannot sustain a chain reaction, because its own fission neutrons are not powerful enough to cause more U-238 fission.

Hess ' law allows the enthalpy change ( ΔH ) for a reaction to be calculated even when it cannot be measured directly.

:" Although theoretical calculations can be made today, the eventually attainable range of chemical reaction cycles, error rates, speed of operation, and thermodynamic efficiencies of such bottom-up manufacturing systems cannot be reliably predicted at this time.

It may be a reaction to a percussive sound, the following movements constituting further reactions.

The most reaction can achieve is stasis, and a stasis that can be maintained only by the expenditure of an effort which ultimately exhausts itself.

Since a civilizational crisis involves also a crisis in private interests and in the ruling class, reaction is normally found among those who feel themselves to be among the ruling class.

The rate of the gas phase exchange reaction appears to be proportional to the first power of the absorbed light intensity indicating that the radical intermediates are removed at the walls or by reaction with an impurity rather than by bimolecular radical combination reactions.

Furthermore, the exchange would not be expected to be sensitive to trace amounts of impurities because it would not be apt to be a chain reaction since the activation energy for abstraction of chlorine by a chlorine atom would be expected to be too high ; ;

Following observation of the fact that the reaction rates of supposedly identical reaction mixtures prepared on the same filling manifold and exposed under identical conditions often differed by several hundred per cent, a systematic series of experiments was undertaken to see whether the difficulty could be ascribed to the method of preparing the chlorine, to the effects of oxygen or moisture or to the effect of surface to volume ratio in the reaction tubes.

By comparing reaction cells sealed from the same manifold temperature dependency corresponding to activation energies ranging from 11 to 18 Af was observed while dependence on the first power of the light intensity seemed to be indicated in most cases.

-- Although there was some variation in results which must be attributed either to trace impurities or to variation in wall effects, the photochemical exchange in the gas phase was sufficiently reproducible so that it seemed meaningful to compare the reaction rates in different series of reaction tubes for the purpose of obtaining information on the effect of chlorine concentration and of carbon tetrachloride concentration on the reaction rate.

The unhealthy use of denial in the initial reaction to a stress must be handled through the medium of a positive controlled transference.

A more tenable explanation for the change in reactions is that the added knowledge and increased familiarity with the total situation made it possible for these subjects to be less guarded and to relax, since any reaction seemed acceptable to the examiner as `` normal ''.

Recent work with radiocarbon and deuterated alcohols as solvents, however, has given evidence that metal-hydrido and carbonyl complexes may be readily formed by reaction with alcohol in some of these systems.

Blowing can be either one of two types -- carbon dioxide gas generated by the reaction of water on the polyisocyanate or mechanical blowing through the use of a low-boiling liquid such as a fluorinated hydrocarbon.

The second reaction can be described using either theory.

Arthur Danto has described this reaction as " kalliphobia " ( after the Greek word for beauty-' kalos ').

It is the most polyphetic known enzyme: six distinct classes have been described, all catalyzing the same reaction but representing unrelated gene families with no known sequence or structural homology.

17th century historian Ahmed Mohammed al-Maqqari poignantly described Abd al-Rahman's reaction as he implored Yahiya to keep going: " O brother!

Chemical reactions are described with chemical equations, which graphically present the starting materials, end products, and sometimes intermediate products and reaction conditions.

Chemical reactions happen at a characteristic reaction rate at a given temperature and chemical concentration, and rapid reactions are often described as spontaneous, requiring no input of extra energy other than thermal energy.

The general concept of a chemical reaction has been extended to non-chemical reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles as described by quantum field theory.

The rate of a first-order reaction depends only on the concentration and the properties of the involved substance, and the reaction itself can be described with the characteristic half-life.

" Art historians have described Dada as being, in large part, a " reaction to what many of these artists saw as nothing more than an insane spectacle of collective homicide.

Exploiting his androgynous appearance, the original cover of the UK version unveiled two months later would depict the singer wearing a dress: taking the garment with him, he wore it during interviews — to the approval of critics, including Rolling Stones John Mendelsohn who described him as " ravishing, almost disconcertingly reminiscent of Lauren Bacall "— and in the street, to mixed reaction including laughter and, in the case of one male pedestrian, producing a gun and telling Bowie to " kiss my ass ".

It describes mental processes as computational operations, so that, for example, a fear response is described as arising from a neurological computation that inputs the perceptional data, e. g. a visual image of a spider, and outputs the appropriate reaction, e. g. fear of possibly dangerous animals.

It was the largest party in Dáil Éireann at every general election from the 1932 general election until the 2011 general election, when it suffered the worst defeat of a sitting government in the history of the Irish state, a loss described as " historic " in its proportions, where it saw its electoral support base diminished by 75 %, as a reaction to the intervention, and in the running of the Irish economy, of the International Monetary Fund and the European Central Bank in November 2010.

The unequivocal monotheism of Islam ( often described as the foundation of the religion and its most fundamental article of faith ) arose as a reaction to this belief system.

Another fairly detailed vehicle system, designed and optimized for crewed Solar System exploration, " Discovery II ", based on the D < sup > 3 </ sup > He reaction but using hydrogen as reaction mass, has been described by a team from NASA's Glenn Research Center.

From the 15th to 17th century, these ideas that are alternatively described as Western esotericism, which had a revival from about 1770 onwards, due to a renewed desire for mystery, an interest in the Middle Ages and a romantic " reaction to the rationalist Enlightenment.

P. J. Plauger, an early adopter of structured programming, described his reaction to the structured program theorem:

For example, the two diatomic gases, hydrogen and oxygen, can combine to form a liquid, water, in an exothermic reaction, as described by the following equation:

2000 KW Curtis steam turbine circa 1905. The first device that may be classified as a reaction steam turbine was little more than a toy, the classic Aeolipile, described in the 1st century by Greek mathematician Hero of Alexandria in Roman Egypt.

The band, described by Smear as " like the Germs, but with worse players ," played only a few gigs to lukewarm reaction before splitting up.

On 15 October 2005, Chow stated in an interview that Lee died from an allergic reaction to the muscle relaxant ( meprobamate ) in Equagesic, which he described as a common ingredient in painkillers.

Many other reaction types have since been described.
