19/05/16 GCSE chemistry edexcel

Any ideas on what may be on the edexcel chemistry paper???

May be wrong of course but my predictions:

1. Electrolysis
2. Uses of calcium carbonate
3. Early atmosphere
4. Fractional distillation
5. Disposal of polymers
6. Formation of rocks

Haha, quietly confident :wink:

I mean rocks hasn't been a six marker in a while. I guess they could do a six-marker on biofuels?

Could you elaborate on what you mean by "formation of rocks" please.

Do you mean growing crystals or extraction of iron? I have never heard the term "formation of rocks" before.

Thanks!

So the six marker could be:

'Describe how sedimentary, igneous and metamorphic rocks are formed.' (6)

However, what you said about growing crystals (via intrusive and extrusive cooling) and extracting iron is also correct.
