The oxidation numbers of hydrogen (H) and oxygen (O) are +1 and -2, respectively. Nitric acid is a neutral compound. Let x be the oxidation number of nitrogen (N). Therefore, +1 + x + (-2) x 3 = 0 Or, +1 + x – 6 = 0 Or, x = +5 3. Potassium Permanganate (KMnO4)...

It also shows the superiorities of high H/C mole ratio, low reforming temperature, high hydrogen storage capacity, the absence of sulfur/nitrogen impurities, and ease of transport [161–165]. The research on methanol-to-hydrogen production technologies will contribute to constructing a methanol-...
The dependence of the formation of NH 4 + and/or NO 3 ions on chemical structure has been examined in TiO 2 photocatalyzed oxidations of various amino acids, amides, and nitrogen-heterocyclic compounds. The primary amino groups and the amide moiety are converted photocatalytically and predominantly...
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.
Lubrication has become essential in enhancing engine efficiency in the era of rapid globalising. The tribological, oxidation and thermal conductivity properties of an engine oil play a vital role in improving the quality of a vehicle’s engine life. In t
Despite the well-documented mineralogy of the Ytterby pegmatite, there are no other Mn minerals reported from the area, but there are a number of minerals in which Mn likely constitutes a minor component. Figure 1. Maps showing the location of the Ytterby mine and the Mn deposit. (A) Map...
(iv) Ozone demonstrates nucleophilic property and nucleophilic reaction occur with molecules especially, when the compound contains carbonyl or double and triple nitrogen carbon bonds [6]. The benefits of ozonation in wastewater treatment plants include sludge reduction and removal of recalcitrant organic ...
