Sushi also utilizes a similar chemical reaction between fish and the acidic content of rice glazed with vinegar.

The anthropological concept of " culture " reflects in part a reaction against earlier Western discourses based on an opposition between " culture " and " nature ", according to which some human beings lived in a " state of nature ".

Energy that can be released ( or absorbed ) because of a reaction between a set of chemical substances is equal to the difference between the energy content of the products and the reactants.

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.

An important example of cycloaddition reaction is the Diels – Alder reaction ( the so-called cycloaddition ) between a conjugated diene and a substituted alkene to form a substituted cyclohexene system.

At low pressure, there was enough space between the gas atoms that the ions could accelerate to high enough speeds that when they struck another atom they knocked electrons off of it, creating more positive ions and free electrons in a chain reaction.

In 1923, the Belgian mathematician and physicist Théophile de Donder derived a relation between affinity and the Gibbs free energy of a chemical reaction.

published a convincing synthesis of < sup > 260 </ sup > Db in the reaction between californium-249 target and nitrogen-15 ions and measured the alpha decay of < sup > 260 </ sup > Db with a half-life of 1. 6 seconds and a decay energy of 9. 10 MeV, correlated with the daughter decay of lawrencium-256:

Distinction is often made between erotica and pornography ( the depiction of acts in a sensational manner so as to arouse a quick intense reaction ) ( as well as the lesser known genre of sexual entertainment, ribaldry ), although depending on the viewer they may seem one and the same.

For example, on reaction between potassium permanganate and sodium sulfite.

Iron corrosion takes place on acid medium ; H < sup >+</ sup > ions come from reaction between carbon dioxide in the atmosphere and water, forming carbonic acid.

Explosives based on ammonium nitrate have little or no water resistance due to the reaction between ammonium nitrate and water, which liberates ammonia, nitrogen dioxide and hydrogen peroxide.

The strength of the reaction could be expressed numerically as an Immunological Distance, which was in turn proportional to the number of amino acid differences between homologous proteins in different species.

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 reaction of chlorine with carbon tetrachloride seemed particularly suited for such studies.

The required amount of carbon tetrachloride was distilled into a series of reaction cells on a manifold on a vacuum line.

The light was filtered by the soft glass window of the thermostat thus ensuring that only light absorbed by the chlorine and not by the carbon tetrachloride could enter the reaction cell.

In the liquid phase runs the amount of carbon tetrachloride in each reaction tube was determined by weighing the tube before opening and weighing the fragments after emptying.

-- 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.

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.

Alkyne trimerization describes the cyclization of three alkynes, in the Dötz reaction an alkyne, carbon monoxide and a chromium carbene complex are the reactants. Diels-Alder reactions of alkynes with pyrone or cyclopentadienone with expulsion of carbon dioxide or carbon monoxide also form arene compounds.

They used a calorimeter to estimate the heat evolved per unit of carbon dioxide produced, eventually finding the same ratio for a flame and animals, indicating that animals produced energy by a type of combustion reaction.

Other specialized cycloadditions include multicomponent reactions such as alkyne trimerisation to give aromatic compounds and the cycloaddition of an alkyne, alkene and carbon monoxide in the Pauson – Khand reaction.

When a hydrocarbon burns in oxygen, the reaction will only yield carbon dioxide and water.

In supernova explosions, calcium is formed from the reaction of carbon with various numbers of alpha particles ( helium nuclei ), until the most common calcium isotope ( containing 10 helium nuclei ) has been synthesized.

One proposed reaction is that of the olivine-rich rock dunite, or its hydrated equivalent serpentinite with carbon dioxide to form the carbonate mineral magnesite, plus silica and iron oxide ( magnetite ).

In this case, one has to use the hydroboration – oxidation reaction, where in the first step, the boron atom acts as electrophile and adds to the less substituted carbon atom.

In a rearrangement reaction, the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule.

* charcoal, which provides carbon and other fuel for the reaction, simplified as carbon ( C );

In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via an intermolecular reaction:

This reaction is strongly affected by catalysts such as manganese dioxide, or the enzyme peroxidase in organisms.

The manganese dioxide is not consumed in the reaction, and thus may be recovered unchanged, and re-used indefinitely.

Accordingly, manganese dioxide catalyses this reaction.

Indium ( I ) oxide black powder is received at 850 ° C during reaction between indium and carbon dioxide or during decomposition of indium ( III ) oxide at 1200 ° C.

Once there, a series of chemical reactions ( the Sabatier reaction coupled with electrolysis ) would be used to combine a small amount of hydrogen ( 8 tons ) carried by the Earth Return Vehicle with the carbon dioxide of the Martian atmosphere to create up to 112 tonnes of methane and oxygen.

Carbon fixation is a redox reaction, so photosynthesis needs to supply both a source of energy to drive this process, and the electrons needed to convert carbon dioxide into a carbohydrate, which is a reduction reaction.

C < sub > 4 </ sub > plants chemically fix carbon dioxide in the cells of the mesophyll by adding it to the three-carbon molecule phosphoenolpyruvate ( PEP ), a reaction catalyzed by an enzyme called PEP carboxylase, creating the four-carbon organic acid oxaloacetic acid.

Selenium dioxide is formed by the reaction of elemental selenium with oxygen:

** Carbon dioxide in water is a less simple example, because the solution is accompanied by a chemical reaction ( formation of ions ).

Recycling of the carbon dioxide has been approached in the literature using the Sabatier process or the Bosch reaction.

# In carbonation, reaction carbon dioxide in solution with water forms carbonic acid.

The chemical reaction produces large amounts of sulfur dioxide meaning that Flue gas desulfurization is an essential part of its manufacture to comply with pollution regulations.

The end-products of the reaction are silicon dioxide, magnesium carbonate and small amounts of iron oxide.
