Ethylene homopolymerization over TiCl4/MgCl2/THF catalysts modified with different metal halide additives (AlCl3 and FeCl2) with and without hydrogen was investigated based on catalytic activity and ...
What is the hybridization of AlCl3? What is the molecular formula for butane? The molecular geometry of the PF_3 molecule is ___ and this molecule is ___. a) trigonal planar, polar b) trigonal planar, nonpolar c) trigonal pyramidal, polar d) trigonal pyramidal, nonpolar e) tetrahedral...
In the Lewis Structure of an AlCl3 molecule, how many nonbonding electrons are around the central atom? What is the Lewis structure of the covalent compound that contains one nitrogen atom, one hydrogen atom, and one carbon atom? What is the electron group geometry of the centr...
This mixed corrosion product includes Fe2O3·nH2O/ FeO (OH)/ Fe(OH)3/FeCl3, and Al2O3/Al(OH)3/AlCl3. Cathodic and anodic reactions explain in Eqs. (4)–(7)56,57,58,59: $${\rm{Anodic}}:{Fe}\to {{Fe}}^{+2}+2{e}^{-}$$ (4) $${\rm{Anodic}}:{Al}\to {{Al}...
(from ~ 2.9 to ~ 5.5 for goethite; and from ~ 3 to ~ 7 for Al2O3and theHUsamples) with NaOH. The adsorption of Al3+onHUfraction was performed by pipetting AlCl3solutions into theHUsamples at concentrations that would lead to the adsorption of 0.09, 0.35, 0.87, or...
