That convinces me that the percentile doesn't apply to O levels.
can anyone solve these please these are the answers
5a i reactants: (aq) (s);
products: (aq) (l) (g)
1
ii 25/1000 x 1.5 x 24 = 0.9 dm
b 0.75 mol/dm3
;
25 cm
i have posted the entire questionproblem is we require to read the whole ques to answer this !
ILL give u a proof,ask any experienced teacher and they will always tell you that without percentile CIEs marking wont exist its like their back bone and most of us would get b or c ! Also the distinction in reality is not necessarily attained by a guy who got full marks but he gets the highest marks so he is given the distinction also another thing is find that notice given by CIE when they introduced A* grade for O Levels in one of the FAQs there it is indirectly told abt PERCENTILE !
Now are u good !

A. hydrolysis
B.polymerisation
C.fermentation
D.substitution
plz explain too b/c i don't get the answer's logic

yup
thnks but can u give some detail on fat hydrolysis? bcuz i don't think i did it and there is something about heating fat with aqueous NaOH .... but y are we using an acid in hydrolysis?? can u give some info about this and also realte it to fats. tanks in advancehydrolysis. its formed from glycerol that is a product of fat hydrolysis
