In molecular fluorescence, energy changes in the vibrational and rotational motions are involved, in addition to the electronic transitions. Reactions producing fluorescent radiation: In the reaction chamber of the ultraviolet fluorescent analyzer reactions producing fluorescence are: SO2→SO2∗(creationof...
Natural gas comes from three types of wells: (1) oil wells, (2)gas wells, and (3) condensate wells. Natural gas that comes from oil wells is typically termedassociated gas. This gas can exist separately from oil in the formation (free gas) or can be dissolved in the crude oil (disso...
Define Watergas reaction. Watergas reaction synonyms, Watergas reaction pronunciation, Watergas reaction translation, English dictionary definition of Watergas reaction. n. 1. A gaseous mixture produced by the destructive distillation of bituminous coal
and carbonate (CO32−) ions. Mollusk shells or mineral precipitates that form by the reaction of calcium or other metal ions with carbonate may become buried in geologic strata and eventually release CO2through volcanic outgassing. Carbon dioxide also exchanges through photosynthesis in plants and ...

The meaning of NOBLE GAS is any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates —called also inert gas.
The individual reactions, along with their forward and backward rate coefficients, must be realistic, that is, the process represented by the reaction should actually occur. Important chemical kinetic steps should not be overlooked. The ratio of the rate coefficients, for a given reaction, should ...
Chemical conversionis the principal operation in a wide variety of processes, including catalytic and noncatalytic gas phase reactions and the reaction of gas phase components with solids. The reaction ofgaseous specieswith liquids and withsolid particlessuspended in liquids is considered to be a specia...
Problems inherent in producing the fuel increase the weight and decrease the efficiency of the COIL laser as a whole. Thus, there exists a need for a COIL laser that has increased efficiency and lower weight than present designs.In another example, gas liquid contactors are also used in ...
First, the electrodes in such electrolytic cell must be separated by a given distance to provide definition. This translates into power loss in the production of heat. Secondly, the presence of liquid electrolytes requires a sophisticated system of seals to prevent leaking of the electrolyte. U....
