    For the question about the overall temperature change in the reaction on C3, what was it? I got 14 degrees but others got 20:/

    You were supposed to use the max temp not final temp, according to all my notes and resources anyway.
    No you were supposed to use the final temperature, cos it asked for the overall temp change
    so it who ever got 14 is right i think

    The question definitely said symbols
    Oh, will I still get the marks if I put the words which were the same as the correct symbol answers?

    Please be this P.S. You seem quite knowledgeable, for the Unit 3 first bit with the periodic table, did it ask for the symbol or word version of the elements in the answers? and if you put words instead of symbols or symbols instead of words, would you still get the marks?
    I'm not very knowledgeable at all to be honest (perhaps it was the B2 'hoax' paper which I made which gave a misrepresentation of myself)... there were some parts which were on the specification but weren't on the notes I used, and I had to revise them the day before the exam.

    I used the symbols, but they'll accept the word version since it's the same thing, and you're still demonstrating your knowledge of properties of different elements.

    i got 14 and i still think its right cos it said "overall temp change"

    All your grade boundaries posts etc make you seem on your game and you got a lot of the answers right so far so don't doubt yourself!

    Thanks, makes me feel a lot better

    I got 20 because it said the temperature change, so surely this would mean the highest change? And anyway, eventually the temperature would go back to room temp, which would mean (by the logic that you are using) that for every experiment the temperature change is 0.

    I got 31.5 but I'm sure both that and 32 are fine.

    they may have a answer range so like 30-32 for that anomaly one

    I found C2 okay! How about you guys? My B2 went really well so If this was my worst one it shouldnt matter; we still have physics
    totally agree with u.... it was gr8 paper!! Physics - i agree - is scary!!

    but the experimenter continued to add the HCL or whatever it was. But who knows it could be any

    Lol, for the anomaly one at first I put 32.5, but then changed it to 32. Glad I did.

    Urgh I totally messed up the last page! It all started with the amount where I put 30cm, then I didn't read the graph properly so put 38degrees as the overall change! That means I got the Q=mcdeltaT question wrong, and then for the last question I had no clue so wrote the neutralisation reaction will releade the same amount of energy -.- that page will bring my grade right down ergh!
    i did that swell but won't you get the marks for error carried forward?

    The best bit about C3 were the first 3 questions, they were nice and easy . Then it all kinda plopped D:

    yo im tellin u postin graid bawnderees dont maik mee clvr u havnt seeen hao meni sili mistaiks i maid.

    For example, I had no clue when I came to the question which asked how the scientist could find the concentration of barium sulfate (or was it barium hydroxide?). I don't like questions which give you loads of information about the method of the experiment, so I answered this last. All I could think of was that the yield of the reaction is never 100% so this affects the calculation of the concentration. I also put 'carbon dioxide' instead of hydrogen as the gas released in the reaction between sodium and ethanol, because I was most likely thinking of the reaction of ethanol and oxygen instead. There are also many two mark questions on ammonia, and I don't know whether what I've written qualifies for two marks or one mark.

    I'm still remaining hopeful that the grade boundaries will be low.

    That's what I did, I wasn't sure if it was right

    For the one about why you'd use a copper alloy in coins instead of pure copper, do you think that 'copper ores are running out so we need to preserve it as much as possible' would be alright?

    Yeh; I emailed my teacher and asked and he said yes because thats why they ask for your working to be shown.
    But to make things worse I used the wrong unit! So thats like 5 or 6 marks lost!

    I don't know, I couldn't think of anything for that one :/. I put because copper is soft. I don't even know if copper is soft -_-
