Trying to learn chemistry, not having much luck. I feel dumb.

How many molecules are present in 1.5 moles of NaCl?

>Closest possibly habitable planet is 11 light years away
>Hasn't even been confirmed to exist yet
>Good chance of being a Venus-like hellhole
Fuck this galactic neighborhood

>>you will never get to see chunks of fucking ultra-negative magnitude comet reenter earths atmosphere while having an end of the world orgy at a major telescope

>>6182077
>>6182148

Is there any way to make math more interesting?

I fucking hate math with a passion, I always have, is there any way that I can make it more interesting and less of a chore?

>tfw one day the human race could be advanced enough to be able to throw a neutron star into a regular star for shits and giggles

We are more less concerned with the symbols A, you find out that A + A will give you A showing that the whole thing goes unchanged. It didn’t change unlike commutativity A + B give B + A there is a change. A started the journey in commutativity and A + B gave us B + A and B started the journey after the equality sign. But in the case of idempotency A + A will give you A showing that it goes unreacted. You started with A and you meet A ,the final result is A. Showing that a man meeting a man A + A will produce a man there is no reaction, it goes unreacted and in chemical engineering you have to send the material back to the reactor for the action to be carried out again showing that it goes unreacted. That is how mathematics has shown that gay marriage is wrong because commutativity proves that gay marriage is wrong. Idempotency also proves that gay marriage is wrong. So these are the principles I have used to prove gay marriage wrong in physics, chemistry, biology, mathematics and by the grace of God I am the only one that has proved this in the whole world.

When waking up from dreams I'm getting 'feels' from my childhood for a few seconds. I want more, what's causing this? how can I prolong it?

Why are academics so stingy? A professor makes almost 100k/year but when it comes to things like conferences, travel, etc., he acts like he's strapped to the bone, like a $20 cab fare would shatter him. Wittgenstein famously gave up one of the largest family fortunes in Europe, Paul Erdos supposedly handed thousands of dollars to a random homeless person, why are today's academics such joyless scrooges?

/sci/, suppose we overcome all logistical problems in establishing a colony on mars, i.e. we have reliable ways of getting food and water, we have reliable shelter. wouldn't a majority of the colonists still die or fall very ill?

from what i understand long stays in environments with a fraction of earth's gravity fuck up the human body even with exercise and change the way microorganisms behave. wouldn't we first need to send animals (primates?) to mars and conduct health tests?

Two hours ago as I was walking downtown I happened to witness what I believe to be a supernova! It was a star that became incredibly bright (1st or 2nd magnitude) before fading back to normal (4th or 5th magnitude). Please forgive my lack of accuracy here. Anyways, I stopped and studied the star as soon as I noticed it flare, and continued to watch it for a minute or so after it had died down. Although there is some atmospheric haze tonight, I am absolutely certain that the incredible change of this star's apparent magnitude was not caused by passing clouds, and it was most certainly a star (not a plane, satellite or anything but a star).

Did anyone else see it? Time of the event was approximately 12:45. I'll try to find which star it was on a chart.

i have been stuck on this problem for about half an hour now can you guys help?

The predominant isotope of gold, 197/79 Au, has an experimentally determined exact mass of 196.967 amu. What is the total nuclear binding energy of gold in electronvolts per atom?

Finished Anki review in 43 minutes -- well within the usual time that takes.

It's now 68 minutes since taking the modafinil.
Pulse is at: 72 BPM

No effects which can't be ruled out as placebo effects, so far. Did this Indian pharmacy send me fake pills?

I will now create 25 new Anki cards from the 3 textbooks and 1 paper which I'm currently reading through. I will report back after.

What is the energy of the future? Should I invest in it?

I like biology, and I think I want to major in it. I would like to obtain a PhD. What kind of career opportunities are there for someone with a masters or PhD in biology? I'm 18 but I'm pretty unsure of all this. I just know I want to go into biology because it interests me. So if someone could maybe guide me a bit, give me some info about the whole field I would appreciate it.

Is there any truth to this? One of my pot- smoking hippy friends insisted on showing it to me.

banks in new transylvania have a desired reserve of 10 percent and no excess reserves. the currency drain ratio is 50 percent of deposits. then the central bank increases bank reserves by 1200

during the first round, deposits increase by $? and currency increased by $?

please help me i am failing so hard
