Chemistry Unit 1 - C1 Chemistry in Our World Specification 2011

I got this from the Edexcel website for the 2011 specification. This should be similar or the same thing as to what your teachers were given to teach you so you need to learn everything on this list. If you are doing the foundation paper than you need to learn ONLY the BLACK  stuff but if your doing Higher learn all of it. If you have any questions or need any more resources let me know and I'll see what I can do :)
