i also took paper 31 my highest temperature recorded in the 9th minute of experiment 2 was 34. I am not sure about this because all who took the same paper in my school reached to values 46 and 50. any idea whose correct?
Im not sure tbh, I did the paper and the experiment was exothermic, and the idea was that at the start of 3 minutes it would increase and then as time goes by, the temperature decreases, like I started with 45 then it was 50, highest was 57 then it decreased, to about 30-40 cant remember sorry but it should be correct, Btw the titration did you get 29.98 cm ?
i started with a temperature of 23 degrees at t=0 and one i added the zinc temperature increased till i reached to the 9th minute where the temperature was 34 degree's. i got my titration rough volume as 29.5 cm^3 and the other two trials were 29.3 and 29.4 cm^3.
i think you cant get your volume to 2 d.p it should be either a 30.0 cm^ if your botom of meniscus was more to the 30 than to the 29.9
And what was the FA6 ? So4 and ?
i said it was copper and sulphate, i asked my teacher he said it should be a carbonate not a sulphate.
i asked my cousin and her highest temperature was 56
lol, looks like i will fail this test. I think the reagents given to me were not well prepared.
dont worry, there's still paper 1 left... do well in that and insha allah u will get an A
inshallah you toodont worry, there's still paper 1 left... do well in that and insh allah u will get an A
, i did well on paper 21, i have no problems with any of the theory papers but my main problem here is paper 31. Do you know how many marks will i loose if both my titration and temperature values are incorrect?.as long as your calculations are correct, u won't lose all the marks, u will probably lose 3 marks for accuracyinshallah you too
Thank' you got my hopes up.That's the only thing i am sure of calculation and the data representation(table and rounding of value's).
then u wont probably lose sooo much marks
one more question, sorry, i know i am asking too much, Do you know what the titration value is or values which are near to the correct one?
Titration values vary centre to centre. Ask the people who performed in the same place as you for accurate reading
it's ok, my cousin got totally wrong, she got around 28, her teacher and classmates got around 29.4
They all got titration values around 29.5-29.8, i got my rough value as 29.6 and both trials 1 and 2 were 29.3 and 29.4, does this mean i am wrong? . I thought all candidates who took the same paper would be expected to get the same values. Maayee sorry for that hope he/she does well on paper 1 .Titration values vary centre to centre. Ask the people who performed in the same place as you for accurate reading
well i think u would only lose marks for accuracy but even some people did get 29.5 from ur centre and ur average titre is 29.4, so i think then it's fine... u dont need to worry that much...you will probably get good marks insha allah
