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 :)

Atmosphere the Earth's early atmosphere
Recall that the early atmosphere contained:
a) Little or no oxygen
b) A large amount of carbon dioxide
c) Water vapour and small amounts of other gases
Explain why there are different sources of information
about the development of the atmosphere which makes it
difficult to be precise about the evolution of the
Describe how condensation of water vapour formed

atmosphere was reduced by:
a) The dissolution of Carbon Dioxide into the oceans
A changing
b) The later incorporatin of this dissolved carbon
dioxide into marine organisms which eventually
formed carbonate rocks
Explain how the growth of primitive plants used carbon
dioxide and released oxygen by photosynthesis and
consequently the amount of oxygen in the atmosphere

Describe that igneous rocks, such as granite, are:
The a) formed by the solidification of magma and lava
atmosphere b) made of crystals whose size depends on the rate
today of cooling
