I'll tell you why I call it shit, because you're basically spending your whole time sniffing the ass cracks of all those professors who invented these frameworks. Ew.

Be a real man, explore the world with your senses.

I meant basic, the problem was in french sorry

That's when it's Practical work, But these are basically calculations and since I can't use any funny formula without demonstrations, I'm lost.
Like who tf would ask for ?f with any other formula than yf/ymax

Lol you just press the - button and the funny log button To get the answer. Sometimes you press the wacky shift then the funny log to get the log10 and you figure it out too.

chem is fun, but you have to get through some of the mundande early shit to have a true knowledge of shit
you'll use a buffer solution sooner than later

chemistry is "mundane shit", all of science is "mundane shit". even in the most applied science field it's going to be 75% theory and only 25% practice.

got any advice for making alkyl nitrites? I bought some glassware and tools to make some, but i'm kinda having trouble sourcing the actual materials(specifically the alcohols. Isopropl is very easy to find, but i dont wanna go blind, so amyl or butyl would be pref.)

Make some spirits like rum or vodka but keep the higher boiling point fractions (fusel alcohols). You can add L-Leucine to the ferment to increase the proportion of isoamyl alcohol produced, as that's the one that you want. Separate it and the isobutyl alcohol by fractional distillation using your proper glassware.

That's a LOT of extra steps i was hoping to avoid. I guess making everything from the ground up would teach me the most tho. After that, i guess i'll look to source a cheap place to buy them, that'll ship to Canada.
