How was Chemistry Paper 12?

[TCHS]

Personally, I did not find it quite easy :/

 

[Iadmireblue]

Moles -.-

 

[speedy20]

Too much calculative questions this year but hopefully went well all thanks to Allah

 

[TCHS]

How come there weren't a lot of repeated questions? :/
I just counted 2 repeated questions :|
I found May/June 2012 to be easier than this one!

1 or 2 repeated Qs. in may june there ere so many repeated Qs.

It was nice. Lots of calculations, but quite straightforward

 

[Prawesh Dahal]

Anyone , predict the threshold. I found it hard too.

28-30....GUESSING

i personally found it quite easy... maybe threshold are gonna be sky high..

It was quite hard! However, section B was nice!!!.But still, grade threesholds will be definately low

is the structure of baked clay giant molecular???

 

[ijjukittu]

is the structure of baked clay giant molecular???

I dont thin so!!! because giant moleculars are only graphite, diamond n SiO2! how they can be in clay??? n i guess clay is made up of SiCl4!

Baked clay is giant molecular structure, it is silica, SiC. SiCl4 is liquid at room temperature.

SiCl4 is simple molecular!
