like 'paste the last thing you copied'. Those really make my brain work and make me post things which make a difference!



I for one really enjoy reading the last thing some one copied, and I thank them for sharing it with us by pasting it here.

you're welcome!!!

Molar Volume:



Molar Volume: The volume in one mole



STP: Standard temperature and pressure



Gas Laws:

Standard: 0C (273K) and 1atm



Molar volume of any gas at ATP is the exact same

wow there are some typos in there I didn't notice

It doesn't make sense though it doesn't matter.

It only doesn't make sense because my spacing got messed up and you have not had chemistry ma'am

(±)cis-2-[(dimethylamino)methyl]-1-(3-methoxyphenyl) cyclohexanol hydrochloride



Looks like I'm not the only one with a lil' chemistry in my copypastezzles.

History >>>>> Chemistry

Hey ossi

sup scott

So whose face is that with mustaine hair holding a panda?

It's a pic of Dave Moustachne and Sexual Harassment Panda 2.0 having a coversation about warzone.

the slayer song?

that is floridly incorrect

no i checked his figures and they are accurate

Quantitative chemistry.



Physical & quantum chemistry > the fuck out of everything.

i would love to fulfill you with my stimulated greatness.

was that t intentional!

Reductive, elitist statements such as this one

Lava, do you have exams where you have to discuss how the laws of thermodynamics make you feel?

[quote name="Dusto"]the slayer song?[/quote]



Nah, warzone was basically the Paki nbb equivalent of cat hallucination.

You sir are a gigantic, pulsating dong.

I am truly offended by the 3rd principle, I'll be writing a stern letter to my professor.

Have you ever browsed the posts in the music forum?

Ive always found them empirically banal.

boy this thread just turned into a sausage party

Awh here goes.
