I was thinking about this:
Let's consider a dissociation of some chemical that can run in both directions:
AB\rightleftharpoons A^{+}+B^{-}
Dissociated form is soluble in a solvent and undissociated form is not - it precipitates.
Then the reaction proceeds to the left much faster than to the...
Ok, that seems obvious. Still I do not understand this picture:
Whether it's acid catalysed, then HCN should add to carbonyl! Or does (CN-) in picture indicates its equilibrium concentration?
Simply put:
Also during (CN-) addition to carbonyl, base catalysation means there is higher...
In Stecker aminoacid synthesis, a cyanide is supplied in salt form that protonates at the beggining:
NH4Cl + NaCN = NH3 + HCN + NaCl
(Info source - http://www.organic-chemistry.org/namedreactions/strecker-synthesis.shtm)
That seems okay, because HCN is weak acid.
According to the source, the...
That makes me more sense, thank you.
When water putted into acid or conversely acid putted into water, the liquid may spit around due to gas expansion, as I see. Also that is different physical process than oleum fuming.
No, that is too simplified.
The reaction takes place on the liquid's surface. The heat of reaction heats up surface's surroundings.
What does there vaporize? Air humidity? Then why does it condensate 1 cm above the surface? Or sulfuric acid with (~300°C, p(atm)) boiling point? Generally, why the...
I'd like to know the physical mechanism of oleum "fuming" on its surface. Dissolved SO3 reacts very exothermically with some air humidity. Why does the mist occur instead of dissolving created H2SO4 in the solution?
Obviously there is an arrangement of matter that represents an honor. Strictly, there has to be some brain structure representing the meaning of honor. Human's brain is probably encoded by its evolution that it recognizes some specific arrangement of matter in timespace (also that is some...
There is an abstract meaning (either created in my brain or even "deeper" existing in physical reality) that those apples are - what we call - two. I consider that meaning as some feeling, or intuition in my brain.
Because there exists such an arrangement of matter that creates a statue of unicorn, or a movie with moving unicorn, or a brain structure that can somehow imagine unicorn. The concept of unicorn is real because there exists an arrangement of matter that we can define as unicorn.
Yes, I know...
However, I thought there is such proof in \mathbb{R} - that is probably false, just because there are no infinitesimal values in \mathbb{R}. Also such operations like:
\frac{\varepsilon^{2}}{\varepsilon} = infinitesimal, because = \varepsilon
are only predicted from the behavior of real values...
I need some proof that division of two infinitesimal values in hyperreal numbers is a real value. That's what I can't see intuitively, but my theory is based on the opposite.
I don't understand - what means something different? If there are no infinitesimal values, I would answer that the number axis is not differentiable. Or, if I consider only \mathbb{R} number axis and there are infinitesimal values, then I may be only 0.
