申请(专利权)人: UNIVERSITY OF SOUTHERN CALIFORNIA 发明人: JM Whelan 被引量: 3 摘要: A process for the oxidation of sulphur dioxide to sulfur trioxide in the presence of elemental nitrogen with minimal oxidation thereof which comprises combining the sulfur dioxide with a predetermined amount ...
Wastes are often complex mixtures of chemicals, however, and both the oxidation state and the particular metal salt present in the waste may be unknown. 然而,废物常常是各种化学品复杂的混合物,氧化状态和废物中存在的那种金属盐也许都不为人所知。 UN-2 Kirchhoff and Bunsen processed 150 kg of...
It can be found that there are two kinds of stationary points related to the unstable wave function: one is from the beginning of pathway, which consists of O3-MSIA complex and the first transition state in the pathway; another is from the end of pathway, which composes of the last ...
Therefore, the oxidation state of SOA can influence the mass loading of SOA in the atmosphere, and is an important parameter required to evaluate the fate of SOA as a result of atmospheric aging. While the oxidation state of SOA is mainly dependent upon the concentration and type of the ...
Calculating Oxidation State of Nitrogen in 2NO + O2 -> 2NO2 2NO + O2 -> 2NO2 "Oxidation of NO" So a reactant - 2NO doesn't seem to lose an electron, it only gains an additional oxygen atom. So, I guess, oxidation is also gain of an oxygen? ... ...
