    Phy:67 Bio:67 Math:79 Chem: 73 My teachers tell me these grades aren't so bad after all but I, however, have a different opinion. How the heck is my Physics and Bio mark the same even though I did not prepare for them equally, anybody else have a situation where subjects have the same mark?

    I think the answer is C by following the bronsted-lowry theory of acids and bases. HNO2 is stronger than HCO3 so HCO3 acts as a base. HCO3 is carbonic acid which doesn't ionise water as much as HNO2. HCO3 is also a component of blood remember?

    The ox.no of N in NCl3 is +3 and in N2 it is 0 change in ox.no=3 so N has GAINED 3 electrons so it's been reduced and that's why 1 is not correct and hence C is the right answer

    I have some depressing news for all of you our paper was 80% similar to W14 31 and the gt for A in that paper is 26 as opposed to our expectation of 21 This might not be the case just letting y'all know and do NOT take it seriously

    Was the temperature rise for mg with hcl(long strip) lesser than mg with ethanoic acid for all of you cos my enthalpy change value for ethanoic acid was more than hcl Ethanoic acid max was 61c and HCl was 59c

    No change delta t remains the same as hcl Check all the previous marking schemes they illustrate the same thing especially w1431
