It's c1 by the way, and i have no clue, some say it might about tje early life of the universe but i thought that was physics... Sorry i'm useless at chemistry but if you revise everything your be fine! Best of luck tomoz

Hes talking about Edexcel :wink:

Additional , I reckon 6 markers maybe chromotography or rate of collsions or maybe comparisons of ionic, giant and simple

thats a really good question. Right now im studying for both child development tomorrow and chemistry and I am so nervous, I'm doing foundation chemistry and I honestly don't know what to expect. Looking forward to reading what others have to say haha :smile:

good luck everyone xx I do AQA btw

Oops, see! I don't even know what exam bored i'm doing, i'm that bad a chemistry. I did c2 foundation and although i'm doing different board my long question was about the structure of an atom, which was lucky!

Im pretty sure they are talking about AQA as i am sitting my AQA exam tomorrow for chemistry...

i suck at chemsitry, in the first paper i got like a 77 out of 120 im doomed DOOMED

i've got a feeling (and i was right for all additional science papers) that the six marker will either be on cracking or fractional distillation. they've never been thoroughly tested as far as i'm aware for aqa x

The Edexcel C2 paper is tomorrow - speaking of which, I should probably start revising for it at some point :h:

I betting chromatography too....how is the experiment set out? and what do you write about if they give youa chromatagrom to analyse ?

Chromatography is used in forensics to find evidence or what pen was used to write something.it can be used to find out colourings in compounds such as ink,paints and foods. Some couloured compounds dissolve better in a solvent this means that because they have different solubilities, the difference is used to separate the different components of mixtures in chromatography. In paper chromatography the samples are placed near the bottom of a sheet of special paper the different components are carried by the solvent at different speeds ultimately separating them the paper is known as chromatogram.
Uses: maybe a possible question
> police are able to analyse samples of DNA to find suspects
.>analyse paints and dyes so that museums are able to mix exact copies of old paints and restore old paintings.
>used for food standards to see if dyes in food are safe to consume.

You may also be asked about the Rf value this is the distance moved by the compound divided by the distance moved by the solvent This is what the equation looks like remember it:

Distance moved by compound
-----------------------–-------------- = Rf value
Distance moved by solvent

Hope this helps
