Density functional theory calculations were performed to study the Lewis acid(Sc~(3+))effects on the reactivity of ultrahigh-valent chromium-oxo species toward both C-H bond activation and sulfoxidation reactions.Calculations confirm that the oxidizing power of chromium-oxo species is enhanced by ...
Lewis Acid/Base: Some metal cations and electrophiles can function as Lewis acids. Similarly, some nucleophiles and ligands can function as Lewis bases. Answer and Explanation: (a) CO{eq}_2 {/eq} It is a Lewis acid be...

How to determine sigma and pi bonds from Lewis structure Determine the number of sigma bonds for carbon, hydrogen, and oxygen atoms in the following molecule. How many covalent bonds does carbon form in alkanes? How many single covalent bonds can carbon form?
So while Congress sets environmental laws like the Clean Air Act, it's up to the EPA to determine how the United States will reach the goals laid out by the legislation. The agency delegates some of its permit-issuing and policy enforcement responsibilities to states and American Indian tribes...
Lead-acid batteries made it possible to start cars without the help of a dangerous and dirty hand crank. Normally, you never have to recharge them—because your car does that automatically. The battery discharges (gives up a little of its energy) to help the car'sgasoline enginestart up, ...
During this time, the winemaker samples the fermenting must and measures the pH or acid levels and sugar content to determine that the fermentation process is proceeding as it should. To make a dry wine, the winemaker will allow the yeast to transform all of the sugar into alcohol. When ...
"We should both just be glad/And spend this Christmas together." The 2008 track was the brainchild of the Hives, who always wanted to do a song with Lauper. "This is a Christmas song whose eggnog has been spiked with acid, and whose...
Re: How to infer the strength of an oxidizing agent from its Lewis structure? « Reply #4 on: June 09, 2010, 05:35:58 AM » Read up on how to determine oxidation states.CrO3 has an oxidation state of 0, due to the chromium's oxidation state of +6 (to counter the -6 from ...
