Dukeofwin, so how about the questioning style? any change?

No! no change in questioning style! As per my teacher!
so to sum up- this year we are gonna encounter a pattern change not a questioning stlye change

 

[Dukeofwin]

it all about wat the ms and examiner report says not ur teacher...dey r not the examiners after all!
or waisay
¯\_(-_-)_/¯ nai manna to na mano

Exhausted! cant prove it any further!
Your choice, take it concerntrated and be happy

erm.... what is the difference between pattern change and questioning style change? it mean there are no longer fixed question like qualitative analysis and titration in paper 4?

Relax, nothing like that! Most of it would be repeat!
even i dont knw what is pattern change! I'm not in contact with my teacher otherwise would have told you!
So just forget any changing stuff and STUDY! they are not gonna ask anything from physics? so WHY WORRY?

help plzzz!! can anybody temme the methods of collection for each gas?

im worry that they would ask about the colour of substance! i still confuse about it...

how to know what gas is soluble or not?

 

[malay]

how to know what gas is soluble or not?

study chapter 'experimental techniques' frm ur chem book n u will know

 

[luckywang]

study chapter 'experimental techniques' frm ur chem book n u will know

erm... my book didnt list it out but i know some common one...
soluble= SO2,CO2,NH3
insoluble=H2,O2,N2
correct me if wrong!

WHAT!! the pattern is gonna be changed?? nowayyy

what are you saying confusing everyone about the question change and pattern change??? If there was to be any difference in paper, a specimen paper would have been given! what is ur source about this other than ur teacher?

Please do not post material which may cause other people to die of heart attack as they have the paper the next day!

someone.... help me on Q8(g)... why the x=2? (f) mole=2..

 

[ashiqbal]

Cant agree on that one! When its aqueous you have to consider it dilute! CIE cannot spoon feed students, they use a term that only students ranging from B-A* can understand! So yeah it Dilute!

if not mentioned, it is concentrated. A long and lengthy discussion has been held before on this same thread, and it was finally proved from the ms that if mentioned only aqueous, NaCl is always taken conc. and btw, only electrolysis of conc. sodium chloride is included in our syllabus!

 

[SALT]

Right back at SALT and MALAY!
I had a pretty good idea about it being dilute

ill still go wid wat i think, if i see any such question ill post it here....

 

[asd]

Aqueous is aqueous. Why are you guys fighting over it being conc. or dilute? :/
Aqueous solution is simply a solution of a substance in water. The solution contains the +ve & -ve ions of the substance dissolved and water (H+ & OH-)
I never troubled myself into thinking whether it would be dilute or not, so I never assumed unless it was mentioned!

OKAY ITS TIME FOR CHEMISTRY NOW GUYS!!!!!!!!! What's the main topics in ATP?

Identification Of Ions
Moles/Titration
Preparation of Salts
Apparatus
Diffusion
