    Have a feeling this test is going to be hard...last years test's grade boundaries were pretty high, suggesting that the test was easy...

    OCR are like that - it's so annoying. For the 6 markers - the first one is always (normally) interpret a table, what does this mean - and then you just say about hydrocarbon based fuels burning incompletely/completely and what's produced and if there are any effects - pretty straight forward. I doubt it will be the Earth's atmosphere one (I may be proved wrong) but I swear the 2010/2011/2012 was like that - so it seems too soon to do again. For C2, last year there was a bit about nanoparticles in a calculator, and why they were used, but i'm not sure if that was the 6 mark question. We did a past paper recently - no idea which - but it was about fractional distillation, so i'm betting on polymerisation and naming some different polymers and their uses OR changing the properties of a polymer. Then for C3 i'm not sure - again I doubt salt, because there was a 6 mark question on that in 2012 - but electrolysis, the formation of sedimentary rocks, chlorine or a life cycle assessment are strong contenders in my opinion. Eurgh time to crack on with revision, in case I kill myself half way through revision good luck to everyone tomorrow!

    Mate what do you write for the table one in terms of incomplete combustion

    Well, if you burn hydrocarbons - hydrocarbons contain just hydrogen and carbon - so if there's lots of oxygen...

    hydrogen + oxygen = hydrogen oxide (water) --> always the same, it's an oxide - only one oxygen, so incomplete combustion or complete combustion it doesn't change.

    Carbon + (when burnt with lots of) oxygen = carbon dioxide

    Carbon + (when burnt with little) oxygen = carbon monoxide + soot (carbon particulates) - this is because there's not enough oxygen to react with all the carbon, so you get some CO and then some soot - the soot falls on buildings and makes them look black and nasty, and CO is a poisonous gas, it reduces the amount of haemoglobin (substance that binds with oxygen) the blood can carry, so you get flu-like symptoms and can die. Then regardless of complete or incomplete, as long as the hydrocarbon fuel reaches a high temperature, you get NO which then goes onto react with more oxygen in the atmosphere to make NO2.

    I hope that makes some sense - i'm doing this from memory, so I think it's right, but someone may correct me

    I know what you mean. I absolutely hate questions about data, outliers, mean etc. Also, why would a SCIENCE paper include maths, let MATHS deal with maths. :mad::mad:

    Sooo the chemistry test is this thursday.. (same day as sociology:mad:)

    Who's ready? Any predictions for the 6 markers?
    I think there will a question of sulfur dioxide and the method to remove it from the flue has such as Alkane scrubbing and sea water coolant acting as alkaline

    omg ikr! I can understand some maths such as energy transfer of bonds and mass in reactants/products because thats actually science, however sometimes they just ask stuff like mean/averages.. not really scientific...
