    well there goes my two marks XD. Yeah you guys are right the logic adds up.

    yeah it was increasing the power of 10 was constant but the values were increasing

    The table of concentrations that caused ppt were based on that effectiveness of charge and the least amount of moles required was for KCL3 which was around 1.02x10^-3 others increased downwards

    Fe203 was postively charged and so the whole question talked about the negative ion of Sulphate and how Sulphate caused precipiation so by that relatonship Arsenic was negatively charged so over here we needed to talk about the positively charged ion

    The reason I choose KCL was that it required the least amount of moles as compare to others, like the concentrations were given so you could calculate the amount required and because it was talking about cation as well.

    I remember it was about 99.48 something, Boiling point increases when you add impurities but when pressure decreases the boiling point decreases as well. It was logical though and i dont know how high pressure would fit to be correct.

    yeah I wrote KCL as well.

    The pressure was low guys because the boiling point of water was below 100 and boiling point is lower when the atmospheric pressure falls from its orginial 101kPA value.

    How was physics paper 12?

    Each teeth produces one wave when it collides with the spring so when it is rotated once 50 waves are produced and as it was rotated 1o times in one second it meant 500 waves produced in one second thus the frequency of 500 and the answer 0.66

    Yeah mine was also A for that question

    How was physics paper 12?

    Tbh I used the energy method where gravitational potential energy - kinetic energy=Frictional force x height(distance) I got C in that question

    What did you guys choose for the hay and cannon ball experiment?

    How was physics paper 12?

    The answer couldnt be C because it was 6 ohm, while D was 8 ohm thus the largest resistance.

    So its final then Kinetics and Enthalpy change are most probably coming tomorrow.

    I also believed that until I saw what happened to us in physics practical.

    I think its also going to be used for rate of reaction.

    CHEMISTRY PAPER 34 On 31st MAY

    Just tell us this , Is tritration coming? or is the rate of reaction coming? or is it the enthalpy change coming?

    No its 0.01

    CHEMISTRY PAPER 34 On 31st MAY

    dude firstly they will give the the error with you most of the time , while sometimes you have to find it yourself which is the least count and if you have take two values such as a tritrate which requires the subtraction of inital and final volumes then you need to multiply the least count by 2.
