haha.. juz reached home.. ytd was physics paper 1 and 2.. din hav time to blog bout it. paper ended at 5 plus. went for dinner at j8.. reached home study for today's chem paper liao.. haah so about the phys paper..
phys paper 1 was not too bad. at first some questions struck me. but stil hav to rush a little to complete it. din realli find out how many marks i lost. but seems like quite a few so far already.
phys paper 2 was bad. real bad. especially the op - amp question which i nv come across b4. the data question was also weird. duno wad they wanted.

and today was chem paper 2. not too bad. i finished it quite early. there were only 5 questions. but all carried lots of marks.. especially on transition elements. 16 marks. hah the ionic eqm question so weird. pD instead of pH. Kd instead of Kw. hhaa anw there was electrolysis of brine which i read in depth about for the first time ytd. lucky me. haha. still rmb the asbestos diaphragm. hah. anw i got some ans frm the first question. pls verify.

Kd = 1.35 x 10^-15
[D3O+] = 3.68 x 10^-8
pD = 7.43
moles of HDO at eqm = 1.46
Mr of cpd Y = 90
molecular formula = C3H6O3









Compound Y with optical isomerism






Compound Z

2 more papers to go. physics paper 3 and chem paper 1. topics i shall study:
1. EMI
2. Dynamics
3. Ideal Gas
4. Quantum
5. Superposition
6. Nuclear Physics
haha juz nice 6 topics for 6 questions. but cannot be too sure. and oh ya.
7. Physics of Fluids. of cuz.
