Step 1: Label Each Compound With a Variable Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. a NH3 + b S = c (NH3)2S Step 2: Create a System of Equations Create an equation for each element (N, H, S) where each term...
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states ...
Nitrogen (N) is the most abundant element of Earth’s atmosphere but occurs in an inert form (dinitrogen N2) largely unavailable for common biological activity. N2 gas is transformed into more reactive compounds (e.g., ammonium NH4+ and nitrate NO3−, collectively termed reactive nitrogen, Nr...

All the numerical calculations were performed with a finite element method based software package (Comsol Multiphysics 3.5a). Because the lasers were formed within the pumped strip along the short side, the system can be simplified into a two-dimensional rectangle in the transverse plane (see the...
The invention discloses a sulfur-resistant and NOx-removing compound mental oxide NH3-SCR (NH3-selective catalytic reduction) catalyst and a preparation method thereof and belongs to the technical field of environmental protection and environmental catalysis. The catalyst is prepared from a structural ...
4) The central metal is named after the ligands. If the complex ion is a cation, the metal is named the same as the element. If the complex ion is an anion, the name of the metal ends with the suffix -ate. 5) Neutral ligands are given their usual name, with some exceptions: NH...
