how was your paper? Mine was fine. i might get an A .
and you other south asians how was you papers?

 

[Amna]

the paper was easy!
but it still didn't go great...
what was the value of Kc? 2.25 or 0.44?

 

[Talha]

yeah paper was easy.. but silly mistakes in each ques made it worse... em still confused bout kc value bcoz 50% were saying 0.44 and 50% 2.25... i got 0.44!... and yeah vats da most abundant greenhouse gas??

 

[Anonymousx3]

Yeah, it was okay.
I made stupid mistakes though!
And I got 0.44 for Kc, but I rushed it so I have no idea whether it's right or not.
CO2 is the second most abundant greenhouse gas, right?

 

[Talha]

i wrote methane

There were no units.
There were an equal amount of molecules on both side of the equation.
At least, that's what I think..

mine was good hoping for A!!!

 

[girlscampisra]

i messed up with kc too.. will i get marks on e.c.f?

 

[girlscampisra]

what do u think gt cud be?

 

[filza94]

i hav no idea!!!!

 

[AizaAnjum]

i got a 0.44 too =S

 

[Umarisawesome]

The units were dm3. I was told. I wrote no units. No units is wrong. Whenever there's water, the units are always dm3 regardless of the moles.

 

[girlscampisra]

whatt? thats not possible.. there were no units!!

 

[girlscampisra]

Kc is the CONCENTRATION, and concentrations's unit can never be dm3.

 

[AizaAnjum]

there were no units

 

[Hateexams93]

i wrote they cancel each other out , so no units ..and Kc lol i didn't even do it , couldn't manage the time , hhh i lost like 20 marks -.-

 

[girlscampisra]

do u think we can cover up for this in mcq's and practical??

 

[AizaAnjum]

hey what was that gaseous reagent in that barium wala question?

 

[girlscampisra]

i wrote Na2CO3 :s.. i guess its wrong!!
