Chemistry p52!

20????? I'm thinking along the lines of

sherpa, i think threshold will be around 20 for A?

17-19. Number 1 was really difficult hey.

i hope! may your words come true^^

And how did you get rid of the excess Hydrogen... I used NaOH but don't think it makes much sense.

i left it blank :$ i messed up the whole of question 1.. NaOH and which reagent?

I said connect the reduction tube to a vacuum

 

[Taci12]

To get rid of excess hydrogen I connected it to excess oxide, think it's ok? :s

If June 2012, the gt for p52 was 16 although the questions were okay !
Then according to me, the gt for nov 12 would be the same or less !

i agree, around 16 fingers crossed! less i dont think, because question 2 was easy, it will be between 16 and 20!

Guys how many marks was for the apparatus thing and the description of expt?
is ecf allowed till table if i messed up in apparatus?

apparatus: 3
description: 4
and yes you might still get your points!

U mean that if i messed up in apparatus, i can still get marks for my table? u sure?

 

[Nishii]

Yes, according to mark schemes, you get

what a bad paper it was!!!

 

[Taci12]

what a bad paper it was!!!

Indeed, but thank God question 2 was decent enough. Grade thresholds are bound to be a bit low. Sometimes though, I like to imagine the things we could do to those Cambridge examiners XD

In question 2 did you all write down units for log(a-x)? A log function has no units. Although the second question was easy a lot of people will end up losing marks because of this mistake.

 

[srijitsharma]

me too! for june 2012, the gt was 16!

all the best! !!

your totally wrong a log function has units

No they don't^.

but

No they don't^.

why in all questions of physics where there is log we must include the units for p5

 

[manu94]

We write "Lg(T/s)" But the function itself doesnt have the unit. A graph of "lg(T/s)"and "X/m" will have a gradient with unit m^-1.
