(solved) Need a Volunteer : Science : How do they guess the chemical composition of things ? Answered
Hello :-) Here is one of my many unanswered questions ... I googled a lot about this one, but so far, I failed to find anything usefull, probably because I don't have the correct vocabulary. That's why I'm asking to you ... I'm still wondering how scientists manage to guess the chemical composition and molecular structure of things ... For example, how do they know that saccharose is C12 H22 O11, and that it's molecular structure is like the picture below ... About crystals, I've read that they use Crystallography to determine the arrangement of the structure ... But how do they do with organic elements ??? Thanks in advance for your help :-) PS : I can't post this thread into the "Volunteer" group forum. It says that I don't have the autorisation. Do I have to join the group too ?
