Hello there, I am a high school student, and chemistry is bashing my brain hard. I am not saying that I do not understand it. I mean that when I have a doubt, where can I ask ? I know PF has a chemistry section, but I prefer maths and physics here. (No offence please). Also I have some to many unanswered chemistry question here and also in some other sites. Can anyone recommend good chemistry forum ? Any site (though not a forum) for asking chemistry questions will also do. Please help !! Thanks in advance.
