Hello, i am new here!

I am really new to chemistry, i know basic stuff like elements and such, but i don't know how combinations work, or how to calculate reactions etc. Are there any really good books to get me started? i'm not looking for an experiment book, i'm looking for something to study with, something that explains equations... I can't really find anything, could anyone please recommend a lecture for me?

Thanks in advance

It sounds like you should start with a good high school level chemistry textbook. There are many of them out there, and they're all fairly similar. You'll need something like that to get the basics. I'll admit, it's not the most fun reading, but once you understand it you're free to move onto bigger and better things.

Perhaps a good start would be the reactivity series.

The elements near the top are more reactive than elements near the bottom of the chart. For example, copper in a copper salt, such as copper sulfate, is less reactive than iron so iron metal can replace copper in the salt to create an iron salt such iron sulfate and copper metal.

CuSO4 + Fe ---> FeSO4 + Cu

In a more exact equation, iron reduces copper in copper sulfate to copper metal and iron is oxidized to iron sulfate.

Cu2+ + Fe ---> Cu + Fe2+


For a different example, if you added silver to copper sulfate solution, no reaction would happen because silver is less reactive than copper.

Try to get your hands on some transition metal salts (such things can be bought on sites in 30 gram or less amounts such as on Home Science Tools) and experiment around in reference to the reactivity series. Good luck and welcome!

I like Chemistry: the Central Science. It is a college-level textbook, but it doesn't assume the reader has any prior chemistry knowledge. I got mine one edition older than the current edition (12 vs. 13) and I got it used, so it cost less than $25. I do strongly recommend you do the problems at the end of each chapter - only practice will make the info stick in your brain. The book itself has the answers to about half the problems (in black ink). I also bought the separate answer book in order to have the answers to the red ink problems too, but you don't have to go that far.

Wikibooks has a free chemistry textbook, it's basic but good. It also is very straightforward and straight to the point. Here: https://en.m.wikibooks.org/wiki/Introductory_Chemistry_Onlin...

I found Khan Academy to be helpful, https://www.khanacademy.org/science/chemistry
