À partir de 1920, les physiciens prirent comme étalon la masse de l'isotope 160, à laquelle ils attribuèrent la valeur 16,000 00 g tandis que les chimistes continuaient à prendre la valeur 16,000 00 pour le poids atomique de l'oxygène naturel [...]. Mais, les deux échelles ne concordaient pas exactement et la valeur numérique du poids atomique était plus petite dans l'échelle chimique [atomic weight unit] que dans l'échelle physique [atomic mass unit], ce qui entraînait des confusions. [...] on décida [...] que l'échelle chimique basée sur la valeur 16,000 00 pour l'oxygène naturel devait être abandonnée. En 1961, les Unions internationales de physique pure et appliquée et de chimie pure et appliquée prirent la décision de recommander une modification de l'échelle des poids atomiques et d'attribuer un poids atomique de 12 à l'isotope du carbone 12 [indice]C, ce qui nécessitait de recalculer les tables de poids atomiques sur la base de 12 [indice]C =12. 4, record 5, French, - unit%C3%A9%20de%20masse%20atomique

The most important carriers of hydrogen in catabolic reactions [are] NADH and NAD+.... The part of the NAD+ molecule known as the nicotinamide ring is able to accept a hydrogen atom together with an additional electron(a hydride ion, H-), forming NADH. In this reduced form, the nicotinamide ring has a reduced stability because it is no longer stabilized by resonance. As a result, the added hydride ion is easily transferred to other molecules. In the biological oxidation of a substrate molecule such as an alcohol, two hydrogen atoms are lost from the substrate. One of these is added as a hydride ion to NAD+, producing NADH, while the other is released into solution as a proton(H+) 3, record 10, English, - hydrogen%20carrier

Carbonation occurs when carbon dioxide is dissolved in water or an aqueous solution. This process is generally represented by the following reaction, where water and gaseous carbon dioxide react to form a dilute solution of carbonic acid. [H2O + CO2=H2CO3] This process yields the "frizz", to carbonated water, the head to beer, and the cork pop and bubbles to champagne and sparkling wine. Carbonation is used to improve both the taste and "texture" of the carbonated consumable. Carbonation is sometimes used for reasons other than consumption, to lower the pH(raise the hydrogen ion concentration) of a water solution... 2, record 14, English, - carbonation

La carbonatation est une réaction qui a lieu lorsque le dioxyde de carbone est ajouté à un liquide à base d'eau. Le dioxide de carbone réagit avec les molécules d'eau pour en former un acide carbonique selon la réaction suivante : CO2+H2O = H2OCO3 (acide carbonique).

L'eau pure est faiblement dissociée en ions H+ et OH-; à 23 °C, par exemple, le produit des concentrations en ions H+ : (H+) et en ions OH- : (OH-), qu'on appelle "produit ionique" de l'eau, vaut (H+) x (OH-) + 10 [exposant-14] 1, record 35, French, - produit%20ionique

Cette notion complexe donne lieu à plusieurs expressions qui sont des quasi-synonymes selon l'aspect qu'on fait ressortir. Un produit chimique se dissocie (dissociation) en ions positifs et négatifs (ionisation) jusqu'à ce qu'il atteigne un certain équilibre (stabilité), variable selon chaque produit. La concentration des ions positifs multipliée par celle des ions négatifs donne le produit ionique, une constante qui permet d'évaluer quantitativement cet équilibre. La constante permet donc d'évaluer l'acidité d'un produit et, par déduction, sa basicité. 4, record 35, French, - produit%20ionique

The hydrogen ion driving the chemical weathering reaction is supplied from external and internal sources. The external source is the acid supplied in bulk precipitation(meteorological input) ;the internal source stems from various biologic and chemical processes procurring within the soil zone. The average external net annual input of hydrogen ion equivalent, observed at the Hubbard Brook watershed over the 1963-74 decade, was 865[ plus or less] 33 eq/ha/yr. 1, record 48, English, - external%20input

Dans certains cas, il sera difficile, voire impossible, de différencier les origines des modifications autochtones et allochtones lorsque les flux des substances découlant des activités anthropiques dominent les processus naturels à l'intérieur d'un bassin versant. Par contre, pour les lacs de régions isolées ou encore pour ceux qui ne subissent aucune perturbation majeure à l'intérieur de leur bassin versant, les apports allochtones domineront l'ensemble des influx vers le lac. Les sédiments de ces lacs seront donc susceptibles de refléter les changements des précipitations atmosphériques des masses d'air venant de l'extérieur du bassin versant. 1, record 48, French, - apport%20allochtone
