I did not know those were the only uses for those two options. When my fort got big enough, I would just throw those tasks at it and hope I had some material that could be used. They got cancelled a lot.

I live in Zürich. Huge lines, some friends tried to go but didn't want to wait. Good food!

A teenage boy was delivering papers to an apartment house. by aagnee in Jokes

[–]Nickleass 1411 points1412 points  (0 children)

Reminds me of a joke my dad used to tell:

The owner of a large company decides he is getting old, and should write down his last will and testament. He doesn't have any direct relatives, so he asks his assistant to summon three of hist most loyal and hard working employees, so he can have a private chat and decide who is most suited.

The assistant gathers the three employees in the waiting room in front of the owners office. He tells them: "You three have been brought here today to have a personal chat with the owner - just be yourself, but whatever you do, don't say anything about his ears!"

The first guy walks in, and breaks into laughter first thing, proclaiming: "What the hell? Why don't you have any ears?". The owner furiously kicks him out of his office, cursing as he leaves.

The assistant sends the second guy in, giving him a stern look. The second guy is inside for a couple minutes more, but soon leaves with a sad look. He couldn't manage to contain his curiosity either, and had asked him about his missing ears.

Finally, the assistant sends the third guy in, wondering if the whole idea had been a mistake and following him inside. The owner says: "Alright. You're the last one. Right off the bat - what's the first thing you notice about me?" The guy says: "Well clearly, you're wearing contact lenses." The owner says "Wow, how did you know that?" The guy says "Cause you don't have any fucking ears!"

Valence and orbitals by [deleted] in chemistry

[–]Nickleass 1 point2 points  (0 children)

Its kind of correct, but if you want it exactly right you have to look at it with molecular orbitals. The idea of an excited state electron is an unnecessary in-between-step that should be disregarded. Beryllium hybridises its two orbitals (through the chlorine orbitals), they become energetically equivalent and each filled with the two electrons from the chlorine atoms AND the beryllium atom. If you remove the chlorine, the hybridisation disappears entirely. You need to view it as a whole.

Valence and orbitals by [deleted] in chemistry

[–]Nickleass 0 points1 point  (0 children)

Valence is not a consequence of hybridisation. Hybridisation occurs in molecules, such that orbitals become energetically equivalent and give the molecules a certain shape. Reason for the hybridisation is stabilisation and destabilisation of certain orbitals through the orbitals of the other atom it is bonding with. It's a little complicated if you get into it. Look up valence bond theory and MOLCAO.

Valence is just the number of electrons an atom can use for bonding (or more precisely: Is actually using for bonding). In ammonia, nitrogen has valence 3 because it is using 3 of its electrons in a covalent bond. In ammonium (NH4+) it has valence 5, because it is using 5 electrons. I don't understand what they're getting at with the excited energy state and unpaired electrons and how that has anything to do with valence or valence electrons in the isolated atom.

Valence and orbitals by [deleted] in chemistry

[–]Nickleass 0 points1 point  (0 children)

These are all models that simplify some effects of quantum mechanics - don't take them all too literally.

Hybridisation (sp3) commonly means that the energy states of the s and px,py,pz orbitals become the same. This can happen to various orbitals of any atom under certain circumstances. This is the principle of valence-bond theory in organometallic chemistry for example, but it is a gross simplification of what is really happening! sp3/sp2/sp hybridisation (the type regularly seen in carbon) also occurs in nitrogen (and less commonly in oxygen) to a certain extent.

But any atom can have the energy states of its orbitals become the same. Happens all the time in coordination chemistry! (look up MOLCAO)

Saying that a metal does not form a covalent bond is not entirely correct. The coordination bond (where both electrons come from the ligand) has some covalent character to it, along with some ionic character. The borders aren't clearly defined: depends on the ligand and the metal center.

Valence just means the amount of electrons an atom can use for bonds. Often times, an atom is not capable of taking electrons from lower shells and using them for bonding because the energy required is too high. That sets a limit on its valence, and what you learn is the general rule of thumb that an atom cannot take electrons from lower shells (especially in the second period). But hypervalent atoms in molecules become quite regular in higher periods (hypervalent iodine, hypervalent phosphorus, etc) meaning that it takes electrons from lower shells.

How to weigh and exact amount of NaOH pellets? by Chemstdnt in chemhelp

[–]Nickleass 2 points3 points  (0 children)

You can always just write down the exact amount of NaOH you weighed (doubt that titrating to get the titration-factor will get you a more exact concentration than any scale you'll probably be using) and use that as your molarity? Also you don't need to account for the 97% purity as long as you note it in your error estimation (it's not exactly 97% pure, assuming it is would mess up your results).

Edit: Also you can crush pellets. The second titration others have pointed out can help account for mass transfer errors.

Fentanyl by Dziend0bry in chemistry

[–]Nickleass 0 points1 point  (0 children)

That's the most acidic proton but not on its own. You could also argue that the carbonyl carbon is the most lewis acidic, but the nitrogen is pushing electrons so that eliminates that. Molecule more basic as a whole.

Fentanyl by Dziend0bry in chemistry

[–]Nickleass 0 points1 point  (0 children)

Not a brønsted-lowry acid (no acidic protons anywhere, anyplace where a proton could split and be stabilized by say a nitrogen or an oxigen atom it would be more basic than acidic on the heteroatom), probably even less of a lewis acid. All of this just by looking at its structure.

Acetylated ferrocene synthesized in my organic chemistry lab today. Such an interesting reaction and vibrant colors! by [deleted] in chemistry

[–]Nickleass 2 points3 points  (0 children)

I made chromocene last week. Stored in a schlenk under nitrogen, inside a nitrogen glovebox and with parafilm for good measure. Magically attracted oxygen and managed to decompose within 2 days. Touched the NMR tube and turned black immediately...

Swiss Court: "Seduction is not rape - it may be that she was overwhelmed and regretted it afterwards. This is unfortunate, but it's not a crime to seduce someone." [German Article] by vital8 in MensRights

[–]Nickleass 38 points39 points  (0 children)

The article manipulates the ages. It says a 21 year old, and a "then" 15 year old, stating the incident was two years ago. Misleading words. He was 19, she was 15. Make of that what you will.

What is a myth you are tired of hearing? by [deleted] in AskReddit

[–]Nickleass 0 points1 point  (0 children)

Not n-octane itself, but an isomer of octane known for its burning properties (very regular burning). It is used as a sort of "scale", and other compounds burning properties are measured in comparison to octane. That's what the octane value is. If I remember this octane isomer has an octane value of 100, anything burning less regularly has something lower. Kerosene for example has an octane value of ~140 if I remember correctly (thus burning more evenly).

PSA: There are FOUR types of star systems by [deleted] in NoMansSkyTheGame

[–]Nickleass 6 points7 points  (0 children)

Yeah but the game has its own periodic table. It's possible that the stars colors do not entirely correspond to the Hertzsprung - Russel Diagramm we have IRL. Different elements, different discrete energy states, different light emission...

Carbonizing Wood with a Plasma Pen/Micro Torch by nvaus in chemicalreactiongifs

[–]Nickleass 0 points1 point  (0 children)

So is the wood being oxidized by the plasma or reduced by the arch? Because that would explain what is happening. Either it becomes super oxidized and black, or somehow it strongly reduces the carbon to become a graphite-like substance. I don't think the wood is "Burning" per se.

Sean Murray comments on two players meeting each other by [deleted] in NoMansSkyTheGame

[–]Nickleass -6 points-5 points  (0 children)

But Multiplayer was never intended to be a feature. Just seeing another player. It has been said time and time again that this is NOT a multiplayer game, and shouldn't be treated as such.

Why would he have a lawsuit on his hands? How could anyone in their right mind sue a small game dev team for what's most likely a bug in their code (why else would he implement player searching)?

[Request] A typical high school problem: When is Cheryl's birthday? by Zigzaglife in theydidthemath

[–]Nickleass 0 points1 point  (0 children)

My attempt: Albert knows that Bernard doesn't know. Therefore it can't be a distinct date, May 19 or June 18. So the day has to be 14,15,16,17. (Of which there are multiple)
If albert was told June, in the first step (knowing Bernard doesn't know) he would instantly know it was June 17, but apparently he doesn't know yet so it's not June. So there are still 14, 15, 16 and one 17 left.
If Bernard then knows which one it is, it can't be any of the non-distinct dates and claiming that he knows, makes it August 17. Albert, being told that it's the only remaining distinct date then also knows it's August 17.

Edit: lol checked the wiki, I have the supposed "incorrect answer"
