Large elements of my answer is drawn from my own notes that I use for teaching General Chemistry II.
What is −0.693?
Radioactive decay processes follow first-order kinetics. A first-order reaction is one where the rate depends only on the concentration of one of the reactants raised to the f...
Again, I just meant that as a lighthearted joke, no way I'd resent someone for typing an answer to a question I was working on
I understand the purpose behind infrared spectroscopy and mass spectroscopy, but UV-VIS doesn't make much sense to me.
Through research, I see that it has to do with electron orbitals, and it has a relation to Beer's Law.
But what exactly can I learn about a molecule from its absorbance/trans...
I studied bohrs model of atom and then the drawbacks of it and then wuantum mechanical model of atom. Now quantum model is according to uncertainty principal and dual nature of matter and it says we can not talk about fixed orbits (uncertaity principle) and can only talk of an area of maximum pr...
The Bohr model is completely wrong and really shouldn't be used for anything other than a historical account of how Quantum Mechanics came about. It did okay for explaining the atomic emission line spectrum for the Hydrogen atom but that is about it. — LordStryker1 min ago
Below is a basic example.
If percent yield is based on a mass, then a >100% yield can result from a product contains materials that should not be there. For instance, a product that should be anhydrous may not be completely dry and water would add mass to the product increasing your yield. O...
It could have been reworded but I think the question is legitimate and a good one to be honest.
Under normal circumstances to think of something being > 100% would be thought provoking because it goes against what we generally understand as possible.
$\ce{HCl}$, Methanol, Hexane, Petroleum benzene
from more polar to less polar?
So I know, $\ce{HCl}$ has the most polarity. Hexane I guess has the less. I guess the order should be like : $\ce{HCl}$>Methanol>Petroleum benzene>Hexane
But I'm not sure of the place of Petroleum benzene
I just noticed that there is a problem when using mhchem to display structures such as sulfate's. According to its manual, they should appear as
But using $\ce{SO4^2-}$ results in
$\ce{SO4^2-}$
which isn't that bad, but is not the IUPAC recommended display.
A workaround is $\ce{SO4{}^{2-}}...
