I understand your question and will answer it, but to remove space is the same as taking an empty bag and remove the emptiness. To let sound move in space do you have to add air or something like that, but it would be so much air that all dust, planets and stars you can see would not be near enough to make any change at all.

If we say it somehow was possible to add air between the sun and the earth, then would we hear a constant random humming, it would not be particular laud but if you got near to the sun, would the audio level be enough to tear all planets apart.

And it is difficult to do lol

I appreciate that wikipedia may describe it like this, but that doesn't make it an accurate description used in chemistry.

This paper, for example, specifically looks at the differences between chemical and hydrogen bonding (specifically by look at bond strength).

>But I get some feeling that even ionic bonds are not "bonds" in your mind, only covalent ones?

I'd argue that the distinction is more categorical than physical.

All chemical bonds are covalent bonds, there's just a disparity in how much the electrons are actually shared.

That isn’t evidence my dude.

Ok well first, you can't "remove" a vacuum because a vacuum is already nothing. You can't "remove" nothing. Second, if the vacuum of space were suddenly filled with some material that was dense enough to propagate sound, we would all instantly die and everything we know would be instantly destroyed, so you wouldn't hear anything.

Do you want that quote explained or do you want it answered?

If the vacuum of space would suddenly be filled with something like the air on our planet we could hear some things. The sun would be loud as a jackhammer 24/7. I'm actually uncertain if you'd be able to hear anything else with the sound of the sun there. Maybe relatively close supernovae, but the sun would definitely drown out most other sounds like space rocks colliding & similar.

So, the trick is that sound needs something to travel through to reach your ears so you can hear it. When you talk, you make vibrations in the air, and those vibrations will move through the air and hit someone else's ears, and they can hear it.

It doesn't need to be air, sound can travel through things like walls or water, just not the same way as it would through the air.

But space doesn't have enough of anything between planets and stars and asteroids for sound to work. The vibrations can't go anywhere, they need something to travel through.

So, in order to make sound work in space, you would need to fill up all the space between stars and planets and asteroids with something. Like air or water, something that sound can move through.

How sound would work now would depend on what you chose, but also this is such a gigantic change to space that it's hard to figure out what would happen next.

I remember hearing that they execute prisoners on certain dates that are significant to the regime. I guess when you don’t have to worry about things like fair trials or legal due process then it’s easier to organise 😒

I would guess it could cause memory leak issues and such, but in all honesty I'm not much for low-level programming details beyond what I did through school and much prefer sticking around the web dev space these days....so I'm not entirely sure the full implications that GOTO would have on memory.

The vacuum is nothingness. To remove nothingness, you add something. When you add molecules, then you might be able to hear sound.

Thats not true. Hydrogen bonding is an intermolecular force of attraction, as in between two molecules, and it certainly doesn't only apply to ionic substances being dissolved. The reason why water is a liquid at room temperature is because of hydrogen bonding between the positive hydrogen ends of one water molecule being attracted to the negative end of a second water molecule.

I think the point you were getting at was intramolecular vs intermolecular forces of attraction, and that in general intramolecular forces are considered to be true bonds, as they hold the atoms in different molecules and compounds together whereas intermolecular forces, not being nearly as strong as intra, are generally demoted to just being weak attractive forces, with hydrogen bonding being confusingly named as its not even a true bond by these metrics. This whole thread seems pretty semantic, 'bond' is just a strong word to describe an attractive force, at the end of the day and at its core a triple covalent bond is not that different from dispersion forces, they are just two ends of a spectrum representing how little/how much energy you need to break an attraction.

It was true they stopped the practice a few years ago. I don’t know about waiting till certain times of the year tho?

Wait so you bought a poster kidney? Was it…a good kidney? 🗿🗿🗿

No... VB Script all the way!!! /s

I am an old fart developer that learned on the old PET's, C64 and TI, the language I learned on, was BASIC\Waterloo BASIC (we are talking early 80's here), GOTO was a staple. I have watched languages go from a "wall of code", to the more structured OOP that we use today.

You brought up and interesting point that I had never thought of, when calling a Function\Subroutine, everything in the calling function is pushed onto the stack, then popped from the stack when returning from the called function, the GC would then "clean up" as you say. But I guess using a GOTO statement would not push and pop the stack, would/could this cause a modern application to have a memory leak, or cause the application to run out of process and/or Heap space?

A hint for beginner developers, be careful of recursive function calls (functions that call themselves) if done improperly, you get into a recursive loop and you will very quickly run out of stack space.

No you just didn’t understand dude

Let me quote Wikipedia, but this is also in agreement with what I learned and sources are given there as well: '''The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bonds" such as covalent, ionic and metallic bonds, and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding.'''

So bonds are just that, bonds. Some are just stronger or more commonly encountered.

Also, dissolving salts involves their ionic bonds, so if we are pedantic, this part involves even more bonds. But I get some feeling that even ionic bonds are not "bonds" in your mind, only covalent ones?

China ended the policy of harvesting organs from death row inmates years ago (over concerns people were being executed just for their organs obviously) and Falun Gong lies about pretty much everything, those people are fucking cultists lol

That is wrong. Soap is very effective at disrupting cell membranes and destroys bacteria. The surface of cells, including many bacteria, is kind of like a bubble of fats. Not exactly days, but similar enough that soap does the same thing and dissolved it. Dissolve the surface of a cell and all the innards spill out. Now it’s not a living cell, it’s a collection of dead cell bits.

Soap will also detach many bacteria and let you wash them off, but soap itself is strongly antimicrobial. It doesn’t contain antibiotics and for most uses there’s no reason to add antibiotics. The same is true for alcohol hand sanitizer: it’s not antibiotic, but it’s lethal to cells.

You could vote yourself out!

I'm waiting for reddit to chime in with all the "they are like..." similes.

They are like Sticky Notes and Post-It (tm) notes.

there are two things going on here and they aren't really related except that they have the same solution. most "dirts" are oils, waxes, and greases. heat softens them and lets the soapy water slip in between the dirt and your skin more easily. it also destroys germs because they don't have a skin. they have a fatty membrane surround, so soap and the mechanical action of washing your hands literally tears them apart.

>Yes, they left out some detail and might( have wrongly implied that the total is always negative, i.e. dissolution is endothermic, but this was not what you called out and this is ELI5, not a journal paper.

Sure, you could argue that his statement was specifically saying that hydrogen bonding - or any other force being used to maintain the solvation of the solute - is exothermic.

But my point remains that this isn't a bond between molecules, and that is an ELI5 level topic.

There is no point in chemistry where anyone would ever suggest that solvation involves molecules bonding. No chemistry teacher would ever say that hydrogen bonds, Van Der Waals forces, or any other intermolecular force is "bonding with the liquid molecules" or that "this creates new bonds."

Shame that I can't comment on a picture cause I would definitely comment on the photo that is an advertisement for kidney selling that I took it in my country!
