1) The oxidation number of the atoms in any free, uncombined element, is zero 2) The sum of the oxidation numbers of all atoms in a compound is zero 3) The sum of the oxidation numbers of all atoms in an ion is equal to the charge of the ion ...
Soon after, studies of gases by English chemist John Dalton, and the first table of atomic weights that Dalton compiled, as well as many new gases discovered by other scientists, were important in supporting not only Lavoisier’s theory of combustion but his whole new system of chemistry based...
The application of ozonation for municipal wastewater treatment has been demonstrated as a promising technology for the removal of a large number of trace organic compounds such as pharmaceuticals, personal care products, and endocrine disruptors present in secondary wastewater effluents and the improvement...

Nitrogen oxides (NOx = NO + NO2) emitted from combustion and natural sources are reactive gases that regulate the composition of Earth’s atmosphere. Nocturnal oxidation driven by nitrate radicals is an important but poorly understood process in atmospheric chemistry, affecting the lifetimes...
and the coordination number (CN) for Mo-O was determined to be about 4 (Supplementary Table6)38,39. The insignificant contribution of Mo-Mo scattering paths to the fitting data of 1Mo9FeAl from EXAFS results suggested the high dispersion of Mo atoms. Energy dispersive spectrometry (EDS) line...
Rocks hydrothermally altered in the absence of oxygen, leave products of alteration which become mineralogical signs of prebiotic chemistry. They are summarized in the cases 2 and 4 of Table 3. The four oxic hydrolyses/oxidations of ferromagnesian silicates and iron(II) monosulfide rocks at 25 °...

Nitric oxide (NO) has important functions in biology and atmospheric chemistry as a toxin, signaling molecule, ozone depleting agent and the precursor of the greenhouse gas nitrous oxide (N2O). Although NO is a potent oxidant, and was available on Earth
