    Chemistry p41: How'd it go peeps?

    question 1 the formula i suggested AlF3 and Al2O3 i drew out AlFl3 in the dot and cross diagram, bond angle 12o degree's and a shape of a trigonal planar. The type of reaction i suggested was a displacement reaction, and the equation was FCl+KBr-->KCl+FBr, Chlorine will displace the bromine...

    Benzene does not react with bromine water, pure bromine and anyhdyrous FeBr3 is required in order for the benzene ring to react.

    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 .

    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?

    inshallah you too :D, 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?.

    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

    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.
