What do you think will come up in Chemistry 32? :)

[HubbaBubba]

I think Enthalpy is coming up. Not sure though..

 

[white rose]

yes thre is chances of enthalpy and cation anion test

 

[white rose]

no no titration...

 

[dark_ruller1996]

Enthalpy and analysis

 

[Manobilly]

enthalpy change is there.Refer to 2007-2009 pastpapers.

 

[Aymen Ezazi]

i dont think titrations are coming.. only entalpy changes and cation anion tests

 

[ruler_of_the_world]

Yea even I've heard from most of the people that chances of titration coming is less n that there will b magnesium ribbon. If its mg then I think there will b more focus will b on enthalpy.
I jus hope it's not lengthy n we r able to finish it on time with Allah's help

do you have any info on the possible cation anion test? the identification i.e.

No I don't n I believe no one does. U jus have to carry out the tests accordingly

okayyy....
thnxx anywayy

Hey guise. How do I find percentage certainity?

 

[ruler_of_the_world]

For eg u have a value 25 with uncertainty +- 0.5 so
0.5/25 * 100

How was it?

 

[Adorkableme]

How was it?[/quote
not bad not good...okayish

 

[aalmuhannadi]

How was it for you guys? Mine was okay not too great, I got for the anion/cations manganese chloride, iron 3 nitrate and zinc sulfate. And for the last two tests the H+ for me was in FB4 and FB6 using the chromate ions and magnesium ribbon with the lighted splint (although i barely got small sparks with FB6 and nothing with FB4 so I just used the other test to prove it was in FB4). Also I did something in the enthalpy calculations wrong because my final answer was -71 point something kJ... but as long as we get the method correct I hope I don't lose too much there.

Hey guys i only wrote my name centre number and candidate number.. But i didnt right anything in the session part. Is it okay

 

[Warrior66]

^yes, that was all you were supposed to write..you didn't have to write anything in the session part.

for paper 32, how many marks was the last page..the question about H+ ion?

 

[hady94]

When I was writing the anions I wrote the correct anion but I forgot to write the charge, do I lose the mark ? ;/
