Chemistry paper 12 discussion!!!!!!!!!!

[brainiac]

hey wat did u guys chose for that barium and silver ions

 

[respect1]

37/40,,,u must be throwing a party if u get such a good mark.. i am scared i that i would get less than 35...

 

[LimeReem]

And what about the insoluble and soluble question in the 1st page?
about the precipitate in water and in.. something xD

 

[respect1]

the thing about the chloride sulphide or nitrate??

 

[moonlight22]

So I might get 37/40

Me too

Considering worst case senario, and the discussion thats been going on I've got 37 :/

but if heat is needed for steel making then i got 38/40
the problem is that I`m just thinking about the mistakes and I can`t revise 4 paper 3

 

[brainiac]

well i m hoping of getting 38/40 .............

hey wat did u guys chose for that barium and silver ions

Answer is "Nitrate" , because Barium sulphate is insoluble and Silver chloride is insoluble, but they are both soluble in nitrate so yeah

The answer was nitrates only. Asked my teacher and she confirmed it.

i sed soluable soluable... not sure Y, but as i read it a couple times it sed the residue was reacted with water and something bout the filtrate.. urgh..

chill up bro u r right heat is definitely needed ........ and dont be so tensed even if u get a minimum of 35/40 u still r able to score i higher A meaning A* .....now just concentrate on paper 3 and study hard inorder to ace it

 

[respect1]

i hate multiple choice.. i usually get in the range 30-35 but in paper 3 65-75....
i found this paper a little confusing and tricky.

 

[moonlight22]

And what about the insoluble and soluble question in the 1st page?

the salt is insoluble in ehanol but soluble in water
so for ehanol it should b a non-metal

for the precipitate thingy, I chose sulfate, nitrate and
as they mentioned barium which is the test for sulfate
and they mentioned silver which is the test for chloride ions
I don`t know y did they mentioned nitrate but the answer might be "D"

 

[JmCullen]

i sed soluable soluable... not sure Y, but as i read it a couple times it sed the residue was reacted with water and something bout the filtrate.. urgh..

OH! that question!!!
what's the answer????
i wrote insoluble for both.
ohnoooooooo!!!!!!!!!

 

[xIshtar]

The answer was insoluble soluble, as the residue was reacted in the first one, and the filtrate in the second..

I might get 38/40 if what I put for the steel alloy question is right, what did you guys put?

 

[brainiac]

i sed soluable soluable... not sure Y, but as i read it a couple times it sed the residue was reacted with water and something bout the filtrate.. urgh..

no i believe it was insoluble and soluble ...........

 

[moonlight22]

me too I HATE MULTIPLE CHOICE effffft and I can`t even start revising 4 paper 3

 

[LimeReem]

I wrote insoluble for both as well =/ dfgdfxhgf!

 

[respect1]

This is the thing bout multiple choice,, there are fixed answers.. stupid me. Nyways paper3 is worth 50% so if i do well in it i would be able to get that A*

 

[xIshtar]

What did you guys write for the steel alloy question, with the two statements?

 

[AStarHunter]

guess what ?! I came late to the exam and I only had 20 minutes left ! I tried to finish as much as I could but well, the stress was astounding !! ugghh...!

OMG ! But did u manage to complete it ?!

ya, but man, I had to go at the speed of light.
Btw, for the cables thing i did aluminum and platinum. what about u ?
