Chemistry

@Orichalcos_Deuteros - If you look into the subject of "Raffinate" you may find some info on your Cu separation process question. :]

Chemistry is physics of the electron shell, no big deal. Concerning reactions, trying to achieve noble gas configuration like krasnaya explained is a good start.

Actually, I am involved in protein chemistry currently. That's really tough.

I knew this topic on lichess would one day come, since it is the most difficullt subject in the world

I like chemistry

Very well for you @Fmuror02, I will study overnight chemistry today, and I will proably understand better, anyway why are the exam questions so tricky in chemistry, why not straight forward questions, my brain hurts!

When I was in grade 6, chemistry was really easy lol, but now as level, I am managing a difficult subject for my life :(

thx @krasnaya!, Ive gotta part of it.
It might be so difficult to indicate a salt which is a mixture of complicated molecules, but I think we are still young for that! 😇😇

@Sarg0n: you are right, the most rigid relation between chemistry and physics is the study of electrons, I always repeat this statement in my mind when studying electrical chemistry.

By the way Sarg0n, are you a chemical doctor?

@Skittle-Head: sorry, I cannot understand what is "Raffinate"?

@BossOfBosses: the aim of exams is to distinguish between students, this will not happen except by casting tricky questions. Generally I like tricky questions, especially when I discuss them with my pals after the exam.
