G.C.S.E's

[samantha nixon]

I did that biology and that chemistry in November. I thought I'd get 2D's or something, so you could be really surprised when you get your results.

Sammie - that chromotography part where it said the red substance could be A, could be B, could be C, or could be D. I missed the lesson on chromotography and the only thing it said in the book was that chromatography is a method used to separate substances based on their solubilities in particular solvents. A and D had rf values of 3.5, so I don't know how there could have been a destinctive answer for that question.

i put the answer as the A and D one aswell but Leanne thinks it was none of them
and we didnt do anything about chromotography either or any of the other stuff on the test lol
