Everytime. Every fucking time I try and synthesize GBL using the Sandmeyer reaction, the temperature skyrockets up to 40c and a bunch of foam forms atop the post reaction mix. I've used many different brands of HCl, GABA, and Sodium Nitrite. I've even begun to use a mini freezer to perform the reaction. And yet everytime the temperature goes up to 40 - 50 degrees Celsius. What in the hell am I doing wrong? I am following all of the instructions, but it's impossible to keep the reaction below 2 degrees C, and to stop the foam from developing, even with a goddamn mini freezer. The rate at which I add the HCl does not seem to matter. The amount of stirring doesn't seem to make a difference either. Could anybody help a complete amateur out? 2 posts omitted.

Sup /chem/,I'm taking general physics 2 this semester and I have the same professor I had for physics 1. Now it's just algebra-based, and I've been through calculus, so I was able to breeze through Newtonian mechanics and all that. However this semester is about electromagnetism, circuits, and optics. All topics I have zero exposure to. Now the professor is new to teaching at the college level, his experience is teaching middle-schoolers. He is very (obliviously) condescending and talks to his class of adults like they are 12. He constantly makes sexist or racist jokes (but on the fence enough to not get in trouble) and is always ranting about his personal life or past experiences. When he finally does an actual problem on the board he always struggles with basic spelling and arithmetic, and often fundamentally misunderstands the physics concept he is trying to teach. Several times last semester I had to quietly approach him after class and explain how everything he lectured that day was flawed and the next lecture he would try to fix his fuckup but he ended up just giving everyone lots of freebies on the exams.My concern is that in this new semester of material I will not get a good exposure or foundation in these topics and might be lost in future courses. Especially electricity and circuits, I really want to learn more about that. I am worried he will teach me some fundamental concepts backward or something. Other than pre-reading the text before class what would you guys recommend to get through this course when the professor is a complete idiot and in my opinion not qualified? 2 posts omitted.

Decomposition, denaturation, and bacterial/fungal consumption would render blood into basic chemicals. As mentioned, full of potassium salts along with sodium/chloride/iron/copper/etc salts. The proteins would be be broken down into various organic chemicals or utilized by the local flora. Any saccharides floating around in the blood would be consumed almost immediately; nature likes sugars.This is just my own speculation. >> Angus Pickshit - Wed, 06 Dec 2017 20:51:45 EST iiuer4oB No.78935 Reply you could probably by some at a nearby storehttps://en.wikipedia.org/wiki/Blood_meal

So I went back to college recently to pursue chemistry, I just got accepted into a pretty good uni to do Organic chemistry.Now since i'm not that young anymore I really need to do well and not fuck this up, so since i really enjoy chemistry and need to make this work i've been putting a whole load of effort into making sure it goes well.Please give me some recommendations for pre uni reading so I can get a head start.Also share experiences? I did a pretty short and condensed course to get here I learned all the basics during that but i've stilled missed out on a lot of stuff an 18 year old would have done at the college level, so i'm expecting my first week at uni to be a bit overwhelming and full of things i need to learn but then i've heard from a few people that it's like that for everyone no matter how much extra reading you've been doing. 27 posts and 4 images omitted.

The society itself isn't based around alchemy but to achieve the golden standard through a thought process. Something against the scientific method but still very valid. It used to be some sort of annoying half-cult but actually provided introspective determination for the members so long as you sign away a bit of your freedom and resources. Kinda like a church or a society of chemists (ACS) that later developed from this structure.Leibniz's concept of a metaphysical Monad can fit nicely into the school of yestercentury. Something that I have yet to be able to understand fully but can see how it would tie to the alchemical societies back then. He predicted nuclear physics through the destruction of monads (mind to matter "transfer) instead of the more widely accepted concept of indivisible "particles". Though obsolete, it can still be applied today.We need more metaphysical quantum alchemists today.
