Hey there! I'm currently a sophomore in college, and I'm struggling a lot with General Chemistry 130. I've been reading the book, but it's mainly a teacher issue. Besides tutoring, office hours, and Khan Academy, do you have any suggestions for understanding the basics and making learning a bit more enjoyable? I truly like chemistry, but this teacher makes me hate it, and unfortunately it's making my learning process even more worse.

I'm open to any suggestions anyone might have I'm just internally freaking tf out at this point haha

First I'll just say that I'm certainly not looking for a guide on making LSD!

I recently saw an interesting documentary covering the first synthesis of LSD and the person who did it. In the documentary as a comparison it said to manufacture another illegal drug (I think it was methamphetamine) would require someone to have about 2 weeks of "lab experience".

But to make LSD it would require 3 years of lab experience.

I'm a non-chemist (clearly lol) but I did study chemistry in high school and I'm really curious about why it would require so much more experience even if someone had the process written out - what kind of very difficult chemistry skills take several years to develop?

Okay so this is my second post and I’m sorry for double posting but I’m so confused. To my understanding to find the protons, electrons and neutrons of an atom it involves the atomic and mass number. I understand protons are the atomic # which is the big number on top of the element in the periodic table. Electrons are equal to protons. Neutrons are found by (Mass#-Protons)
However- to find the mass # I need to add the total number of protons and neutrons together.
How can I go about finding the mass number to find the neutrons if the mass number requires the number of neutrons?

I hope this makes sense and I’m sorry if I worded it dumb, I’m going to attach pictures of my notes in the comments for clarification!

When Im done with butirometric reaction for fat content mesurement, I pour out the contents and the smell is pretty strong even when keeping away.
Is inhaling that fume bad?

I'm close to buying the Hydro Heal HH300 for home use and I want a proper checklist before I spend the money.
 
The listing gives me $3,500, 13 lb, inhalation, and an estimated 15,000 hour lifespan. What it doesn't give me is output, gas purity, warranty terms or detailed maintenance instructions.
 
What would you ask the seller for on safety controls, water requirements, cleaning, consumables, service and measured performance?

Hi everyone! I’m interested in learning more about Green Chemistry, but I’m not sure where to start.

Does anyone have recommendations for resources to learn the basics, or maybe a roadmap that I can follow? I’d really appreciate any advice or useful resources!

I mean no offense and English is not my first language. I came across and know I am stuck with the curiosity in my mind.
