What is the oxidation number of the chromium atom in K2CrO4 ? What is the oxidation number of the chromium atom in K2Cr2O7? What is the oxidation state of rutherfordium? What is the oxidation state of manganese? What is the oxidation number of nitrogen in HNO2?
A process for the oxidation of ammonia to nitrous oxide in the presence of elemental nitrogen with minimal oxidation thereof which comprises combining the ammonia with a predetermined amount of oxygen containing gas to give at least 1% stoichiometric excess of oxygen for the oxidation of ammonia to...
3.2.2 Re-oxidation of sulphide When the produced sulphide from anoxic zones of CWs is transported to the oxic zones with the presence of available electron acceptors, it may be oxidized back to polysulphides, elemental sulphur, thiosulphate, tetrathionate or sulphate by either chemical or biologic...
Inorganic reactions important for the nighttime chemistry of nitrogen oxides in surface air were studied. The experiments were performed in a new, large re... TF Mentel,D Bleilebens,A Wahner - 《Atmospheric Environment》 被引量: 198发表: 1996年 Atmospheric Chemistry and Physics Elemental compositio...
A common approach to understanding composition–function relations involves the use of simplified model systems with more tractable structures that can potentially remain uniform with changes to elemental composition of the oxides. Isolated oxide domains on supports or as gaseous clusters inside tandem ...
Surface oxidation states of ultrafine particulate matter can influence the proinflammatory responses and reactive oxygen species levels in tissue. Surface active species of vehicle-emission soot can serve as electron transfer-mediators in mitochondrion.
based15N incorporation confirmed activity of all measured cells (see section below: Growth on nitrogen from air), supporting our approach for energy yield estimations. However, we acknowledge that differences in activity between individual cells and potential inaccuracies in the quantification of cells co...
We also found that PEI/SiO2 lost 60% of the initial nitrogen content after the oxidative aging (Supplementary Fig. 2), which could be attributed to the hydrolysis of terminal imines to produce NH342,43. Notably, carbon content also substantially decreased (32%), which indicated a substantial ...
Heterotrophic activity, primarily driven by sulfate-reducing prokaryotes, has traditionally been linked to nitrogen fixation in the root zone of coastal marine plants, leaving the role of chemolithoautotrophy in this process unexplored. Here, we show tha
Uranium nitride (UN) microspheres were fabricated by the internal sol-gel process at Chalmers University of Technology [31,32]. The reported amounts of nitrogen, carbon and oxygen, as well as the associated errors in the triplicate measurements (given as one standard deviation), were 5.72 ± ...
