To calculate the oxidation numbers for N(NH4), count the number of atoms, draw the lewis structure by adding bonds, assign electrons from each bond, and count the number of electrons assigned to each atom. Count Atoms Use the chemical formula, N(NH4), to count the number of atoms of ea...
The reactions of the neutral phosphonoselenoate [Cp(CO)2FeP(Se)(OiPr)2] (1) with Lewis acids (GaCl3, InCl3) produce dicationic complexes [{Cp(CO)2FeP(OiPr)2}2Sen][GaCl4]2, [n = 2 (2), 3 (3)] and [{Cp(CO)2FeP(OiPr)2}2Sen][InCl4]2 [n = 2 (... RA Potts,AL ...
(0.37 cm.3g-1 and 3.8 nm).The large amount of Lewis acid and the moderate amount of Bronsted acid in the H-(NH4)-β zeolite was examined by means of Pyridine-IR spectroscopy.Compared to conventional H-β zeolite,the conversion in the catalytic cracking reaction of mixed C4 hydrocarbons ...

In this work, we report the synthesis, crystal structure determination, and properties of three decavanadates, i.e., (NH4)2[Co(H2O)5(β-HAla)]2[V10O28]·4H2O (1), (NH4)2[Ni(H2O)5(β-HAla)]2[V10O28]·4H2O (2), and (NH4)2[Cd(H2O)5(β-HAla)]2[V10O28]·2H2O (3)...
The structure of symptoms observed in the protagonists of two Asian American narratives makes visible the submerged reasons that have led to their suffering and to the identity crises that are symbolized by the initials of their marital names "M" and "K." Their worlds, which exist only in ...
