There are three main commercially available methods to convert natural gas into hydrogen and carbon by-products : 1) Steam methane reforming(SMR) which uses high temperature water as an oxidant and a source of hydrogen, 2) Autothermal reforming which use both water and air oxidants, and 3) Pyrolysis which relies on methane splitting into hydrogen and solid carbon using high heat. 1, record 1, English, - autothermal%20reforming

C'est pourquoi leur développement a moins pour but le stockage d'énergie électrique que la récupération de l'énergie libérée pendant le freinage d'un véhicule (par exemple un autobus).

Tritium is a hydrogen atom that has 2 neutrons in the nucleus, in addition to its single proton, giving it an atomic weight near 3. Although tritium can be a gas, its most common form is in water, because, like non-radioactive hydrogen, radioactive tritium reacts with oxygen to form water. Tritium replaces one of the stable hydrogens in the water molecule, H2O, and is called tritiated water. Like H2O, tritiated water is colorless and odorless. Tritium has a half-life of 12. 3 years and emits a very weak beta particle. 4, record 9, English, - tritiated%20water

Ozone therapy is probably the most powerful of the oxygen therapies as ozone is more active than the other two main methods – hyperbaric oxygen and hydrogen peroxide therapy.... Ozone is an activated, trivalent(three atoms) form of oxygen. Oxygen is O2 whereas ozone is O3</sub>. Over a period of 20-30 minutes, ozone breaks down into two atoms of regular oxygen-by giving up one atom of singlet oxygen. Medical ozone is made when Medical Grade Oxygen is electrically activated(using an ozone generator) to form ozone. Ozone is germicidal, bactericidal, and fungicidal.

In reference to monohydric alcohols, amines, and a few related compounds, this term [primary], together with secondary and tertiary, describes the molecular structure of isomeric or chemically similar individuals. Monohydric alcohols are based on the methanol group,-C-OH, in which three of the bonds [up, down and left side] of the methanol carbon may be attached either to hydrogen atoms or to alkyl groups.... A secondary alcohol has two alkyl groups and one hydrogen.... The three types can be readily identified by the number of hydrogen atoms attached to the central(methanol) carbon atom : if it is 2 or more, the alcohol is primary; if 1, it is secondary; and if zero, it is tertiary.
