From our friends teaching organic chemistry at UCLA: R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule. Sometimes used more loosely, to include other elements such as halogens, oxygen, or nitrogen. R is an abbreviation for radical, when the term radical applied to a …

If E° of a Half Cell is based on the chosen reference Electrode (Generally SHE) then how is the equation ΔG°= -nFE° be valid for a Half Cell. For example let us take the reaction: Zn (s) ---> Zn^2+ (aq) + 2e^- (aq) ;ΔG°, which we are considering as our half cell And now suppose, by taking the value of E° of SHE (Standard Hydrogen ...

Viewed 11k times. 15. I searched for the strongest oxidising agent and I found different results: ClFX3 C l F X 3, HArF H A r F, FX2 F X 2 were among them. Many said ClFX3 C l F X 3 is the most powerful as it oxidises everything, even asbestos, sand, concrete, and can set easily fire to anything which can't be stopped; it can only be stored in ...

From chemistry stack exchange, an answer contributed by user R.M.: SMARTS is deliberately designed to be a superset of SMILES. That is, any valid SMILES depiction should also be a valid SMARTS query, one that will retrieve the very structure that the SMILES string depicts. Except, that last clause isn't true. Try matching tritium against itself.Cross-posting is not considered the correct way to go on Stack Exchange. Or anywhere on the internet, to be a little more precise.

(But not very acidic.) An elegant way of describing the situation is that Mg (OH) 2 is a strong electrolyte but a weak base (Ref 2 and 3).Dec 24, 2014 · Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry.
