I'm Not There

I'm Not There is a 2007 biographical musical drama film directed by Todd Haynes and co-written with Oren Moverman, inspired by the life and music of American singer-songwriter Bob Dylan. Six actors depict different facets of Dylan's public personas: Christian Bale, Cate Blanchett, Marcus Carl Franklin, Richard Gere, Heath Ledger, and Ben Whishaw. A caption at the start of the film declares it to be "inspired by the music and the many lives of Bob Dylan"; this is the only mention of Dylan in the film apart from song credits, and his only appearance in it is concert footage from 1966 shown during...

> O soft embalmer of the still midnight,
Shutting, with careful fingers and benign,
Our gloom-pleas'd eyes, embower'd from the light,
Enshaded in forgetfulness divine:
O soothest Sleep! if so it please thee, close
In midst of this thine hymn my willing eyes,
Or wait the "Amen," ere thy poppy throws
Around my bed its lulling charities.
Then save me, or the passed day will shine
Upon my pillow, breeding many woes,
Save me from curious Conscience, that still lords
Its strength for darkness, burrowing like a mole;

is 100% H2SO4 acidic?

why do people use 98% instead?

H2SO4 + 2H2O -> 2H3O+ + SO4^2-

Wildcat

Although 100% sulfuric acid can be made, this loses SO3 at the boiling point to produce 98.3% acid. The 98% grade is also more stable for storage, making it the usual form for "concentrated" sulfuric acid.

DHMO

@Wildcat interesting

why is Ca(OH)2 strong although its pKb is larger than 0?

Wildcat

Sulfuric acid

Sulfuric acid (alternative spelling sulphuric acid) is a highly corrosive strong mineral acid with the molecular formula H2SO4 and molecular weight 98.079 g/mol. It is a pungent-ethereal, colorless to slightly yellow viscous liquid that is soluble in water at all concentrations. Sometimes, it is dyed dark brown during production to alert people to its hazards. The historical name of this acid is oil of vitriol. Sulfuric acid is a diprotic acid and shows different properties depending upon its concentration. Its corrosiveness on other materials, like metals, living tissues or even stones, can be...

@DHMO Acids with a pKa of more than about 13 are considered very weak, and their conjugate bases are strong bases.

That is what Wiki says.

Nothing.

What is the required research for the average soft question?

Nothing.

No.

DHMO

Is the accept mark dedicated to the correct answer?
No.

Rubisco

Are the upvotes on soft questions indicating question quality?

No.

@DHMO Your point being? Accept mark is just some extra influence on the OP's side. Nothing breaks if it's not there.

That many questions without accepts hurt nothing on the site.

DHMO

Does every answer have a correct answer?
No.

So the problem with not one right answer is not acceptance.

@DHMO Huh?

@DHMO You're missing the point, pal. For the past two years, I've been arguing about these things all over this place, so you can't beat me. While you see soft questions as a bit of extra fun, the people that moderate the site see them as extra crap they have to take in. I don't want extra crap.

thanks :)

Wildcat

Well, the fist trend you mentioned is pretty trivial. Orbitals with same $l$ are of the same shape, say, s-orbitals are spherically symmetric. So the bigger is $n$, the further from a nucleus an electron should be (at average), cause electrons occupying lower orbitals with same $l$ value are highly likely to be close to the nucleus.

Well, yeah.

It is not that simple. XD

Rubisco

@Loong I remember an enzyme friend of mine that drowned in a glass of reboiled water

Wildcat

3:06 PM

In principle, electrons try to stay as close to a nucleus and as far away from each other as possible. For same value of $n$ this can be achieved through completely different pattern of angular distribution.

getafix

@Wildcat never is haha

carry on..

Loong

@Rubisco probably dioxin poisoning

Wildcat

@getafix That is clear. What else is clear is that at average 3s electrons stay closer to a nucleus than 3p ones...

getafix

indeed.

Wildcat

Oh, wait! I think what else is important, is that despite 3p having its highest max to the left of that for 3s, the later has its closest to the nucleus max to the left of 3p.

So, 3s electrons can "penetrate" towards the nucleus more efficiently, so to speak.

getafix

3:11 PM

yeah true.

Wildcat

@getafix chem-is-you.blogspot.ru/2012/10/…

The very last paragraph reads:

4. Although, s-orbital has the biggest radius but it has local maximum that is the closest to the nucleus compare with p and d-orbital. It means the electron sometimes spend closely to the nucleus. This phenomena is called the penetration, which means s is more penetrating to the nucleus compare with the other orbitals.

:D

At least, it is not only me who thinks in the above mentioned way...
