As you have not specified what you are after I will suppose you are interested in quantum chemistry because it is arguably the main area of study in computational chemistry. I would …The AgX+ A g X + ion and the ClX− C l X − ion are close to the same size (with the silver ion being smaller), so they can approach each other quite closely. In silver nitrate, the NOX3X− N O X 3 X − ion is larger and does not allow as close an approach as the chloride ion, so the bond is weaker, easier to break up, and the salt is more ...Thanks for contributing an answer to Chemistry Stack Exchange!

This will be the end of the monosaccharide which is numbered lowest. For aldoses, this carbon would be carbon 1. For ketoses, it's the lowest number that can be reached in the linear, ring-open form (e.g. for fructose, it's 2).Apr 2, 2019 · Yes , it is a scam . This has been discussed at National Association of Corrosion Engineers meetings for decades. The vendors have actually sold some to refineries; however they can never demonstrate good results in objective tests. The excuses the vendors find for the failures are a tribute to creative thinking. – blacksmith37.

The intersection between the wafer surface and the (122) plane is a line parallel to (1,1,1) x (1,2,2) = (0,-1,1). The angle between these two is 120 degrees. Because of the symmetry of the wafer, other solutions are 0 or -120 degrees. (You would get those by dialing in the (212) or the (221) plane.)Here is how I understand it, armed with the new knowledge contained within the posts above: In the phosphate ion we have a central Phosphorus atom, with five valence electrons. This is bonded to four oxygen atoms, which have six valence electrons. Five P electrons plus 4 times 6 O electrons gives 29 electrons. J.D.Lee writes in his book Concise Inorganic Chemistry:. An alternative method for determining the symmetry of the molecular orbital is to rotate the orbital about the line joining the two nuclei and then rotate the orbital about the line perpendicular to this.If the sign of the lobes remains the same, the orbital is gerade, and if the sign changes, the orbital is ungerade.Data Exchange.

So the theoretical, or stoichiometric ratio of air to fuel is 1740/114 or about 15. Most motor fuels are not pure octane. The additives complicate the math a bit, but the stoichiometric ratio is around 14 for many fuels. The equivalence ratio is just the actual air-to-fuel ratio divided by the theoretical.Apr 3, 2017 · There is a lot of work associated to create such a database, or software.

Carbon Dioxide (CO 2) readily dissolve in water and form Carbonic Acid (i.e H2CO3 (aq) ) This is the formation of bonds. Then Carbonic Acid (i.e H 2 CO 3 (aq) ) dissociate in water as follows. So water gets H + ions, so that cause water acidic. The following shows dissociation of Carbonic Acid (i.e H 2 CO 3 (aq) ) more clearly.May 28, 2015 · Today this reversible lithium-halogen exchange reaction can be formulated as, RLi +R′X↽−−⇀K R′Li +RX. R L i + R ′ X ↽ − − ⇀ K R ′ L i + R X. As an equilibrium process, we know that the more stable lithium species is preferred. Interestingly when R′ R ′ = aryl (particularly bromides and iodides) this is best written as, This would be a strong acid too and the inflection point would be that for water at pH 7. Note that the pKa 1.69 is assuming HX+XX− H X + X X − and is taken at 1/2 of the NaX+OHX− N a X + O H X − used. Knowing that HX2SOX4 H X 2 S O X 4 has two protons, the second pKa should be taken at 150% on the plot which would give the correct pKa ...Are you considering subscribing to Hulu and wondering what channels are included in their lineup?

More exactly, it also includes single atoms, e.g. for a case of noble gases, due the way how IUPAC defines a molecule. But remember the Avogadro law implies ideal gases, similarly as the Gay-Lussac's law, Boyle's law ...Addendum: The process is not a Robinson annulation, which involves an initial Michael addition followed by an aldol condensation. The latter reaction includes the transformation 3 → → 8. The transformation 1 → → 3 may described as a retro -aldol reaction. You may want to see the formation of mesitylene (1,3,5-trimethylbenzene) from ...That is, for core electrons in gold, the electrons are traveling at a significant fraction of the speed of light ( e.g., ~58% for Au 1s electrons). This contracts the Bohr radius of the 1s electrons by ~22%. Source: Wikipedia. This also contracts the size of other orbitals, including the 6s. The absorption you see is a 5d → 6s transition.Newest 'chemistry' Questions - Worldbuilding Stack Exchange. Questions tagged [chemistry] Ask Question.
