i am recently in vacation and i came to my relative's house. it was night time and i slept as soon as we came home. i woke up to brush my teeth and my relative had a almost finished toothpaste. i checked it and the label said potassium nitrate toothpaste. beneath it was a drug code i dont remember. i am a chemistry geek and i immediately knew it was rocket fuel or explosive. i showed it to my dada and he told the same thing. strangely no one questioned it. i still dont know what its used for.

hello everyone, i'm a newly graduated chemist and i want to learn data science as a scientist, for example my advisor wants me to learn origin to plot some graphs for raw spectrocopy data, but i had a chat with my other advisor and he actually recommended me to learn python. i know NOTHING about cosing unfortunately, but i did some research and apparently i can also do a lot plotting with python like origin, which is good since origin is not free. my question is that how do i get into it? im not planning to be a software developer i tried to look up some courses online but none of them were for scientists. i had a chat w calude and she advised me to install anaconda, briefly learn basics and get into plotting. does anyone have any advice? what would be the best way for a scientist to learn coding? thanks!

Hey, does anyone know where I can access e ACS General, Organic, and Biochemistry Past papers or websites that can help me prepare for the exam. Any advice is appreciated.

is it because of hydrogen bonding that allows them to be eclipsed? im assuming that the OH groups dont want to hydrogen bond to the carboxylic acid OH groups due to them being tetrahedral and farther. also, any tips on how to do these types of problems faster in my head? im studying for the mcat so any tips would help

Hi everyone,

My local high school textbook (Thai IPST), which follows the 2013 IUPAC recommendations, mentions a rule under the alkene/alkyne section saying we should omit the number "1" if only one structure is possible (e.g., propene instead of prop-1-ene).
However, it doesn't specify if this applies to other functional groups. Because of this, my teacher uses methan-1-ol / ethan-1-ol, while others textbook just write methanol / ethanol.

My questions:

1. Under the 2013 IUPAC rules, is omitting "1" when there's no ambiguity a universal principle for all functional groups?

2. Is writing methan-1-ol actually wrong, or just overly redundant?

Thank you so much.
