Hey 06s14... juz wanted to say happy holidays :) although not so much of holidays lahh.... since everybody mugging for prelims and A levels.. But never mind, can think of the holidays after that yeah? except for tingyang, who still wants to mug at the chalet.

Anyways.... I came across something which I think may let us do something together after A levels....

Standard Chartered Marathon. No... not run the marathon... but we can do volunteer work there.... got pre-race days and on race day itself which is 2nd dec (1 day before grad nite) so yup.... thought maybe we can sign up as a class and have the same positions or smth =)

most, if not all the dates are after A levels. there's probably one or two briefing dates in the midst of A levels, but can always just send one or two person down to go for it.. don't think it'll b a big deal also.

oh.... there are ALOT of positions available.
http://www.singaporemarathon.com/en/volunteers/?pg=2&sec=209&ssec=574
go there and check it out....

maybe can tag on what you all think of the idea? then we can all sign up together? i dont know if there is a deadline for signing up or not... but perhaps better to do it asap...

juz contributing my share to the class. heh...

meanwhile... happy mugging!!!!

hey these are the missing answers to the prelim paper (chemistry)..(after my session with lkp)

Either 5b) need to know that Mg + NH3 ---> Mg(x)N(y) + hydrogen
Mg(x)N(y) + water -----> Mg(OH)2 + NH3
u balance then u will realise that x=3 and y=2.. (coefficient of water is 6)
the figures are just there for u to check your final answers..

5di) Ksp of BaCO3 is lower than that of CaCO3..
if small quantities of CO2 were to be detected..
BaCO3 is preferred becos the [ carbonate ion] might be high enough such that the I.P of BaCO3 is higher than Ksp of BaCO3 but low enough such that I.P of CaCO3 is smaller than Ksp(CaCO3)..

dii) one disadvantage of using Ba(OH)2 is becos its such a reactive base such that it will be able to react with CO2 in the air...

5 or) i) to blow out the bromine gas into the vats

ii) bromate(V) is produced becos Br2 react with OH- ions in the sea to form bromide ions..bromate(v).. and water..( the 3-6-5-1-3 equation)

5c) the ans is ICl3..( 1.83g refers to AgCl)
find no of moles of Cl-
find no of moles of Iodine that reacted with s2o3..(brown solution is iodine solution)
compare mole ratio..should be 3/2the equation: IxCly + I- ---> iodine + Cl-
then balance!

ok gd luck for prelims.. and btw if u haven realised..polymers and monomers out of syllabus...so no need mug that much after all..(i hope everyone stops mugging to visit the class blog for a while!!)HAHAHAHA

okay. the above was the courtesy of qingsheng so if you still have any questions i think you can ask him.

if you want the original email he sent to me, you can ask me! (: ok. happy mugging!
