[Princess Raven]

just gave my chem paper 32​

it was just ok.. :/​

as they mostly asked questions from the topics which i thought were too easy to even go through therefore i ended up neglecting them ​

and now the surge of regret is too damn high.. ​

curve's sure gonna be high this year.. ​

to all those who still aren't done wid their papers, GOOD LUCK!!! ​

and a tip: Go through all the topics thoroughly.. <kinda obvious tip, bt i cant tell the questions now can i? >​

​

to all those who are done wid their chem paper 32, wt was the answer of the last question?????? ​

ya WTH WAS THE LAST QUESTION?!!!

Moles =Mass/Mr
Moles=Volume(dm^3)*Concentration
Moles=Volume/24
%yield=Actual Mass Made/theoretical yield*100
%purity=actual mass reated*Initial Mass uses*100
hope that helped

guys.. if electrolysis came in paper 6 it does not mean it wont come in paper 3...
study that too..!

ofcourse.. we still have to study it.. and even if we were SURE it wouldn't come, its too LATE to tell them not to study right?? I mean who would keep something annoying as electrolysis for last moment?

OK ur partially right i mean most ppl are busy doing other subjects
Its never late 4 hours is MORE than enough to cover Electrolysis properly
But Yeah if ur been playin around and wasting time then its kinda useless to keep panicking in the last hours
Well i dont mean you i mean ppl xD

50 cm cubed is the same as 0.05 dcm cubed
This is because 1 dcm cube is equal to a 1000 cm cubed

i understand that part i mean the number of moles which could be formed for SrCl2.6H2O

 

[salman moosa]

Same to u......jus hope the ppr goes gud

Look at the ratio for the moles in the equation it is 1:2 so that means it should be half

Apparently, it was Calcium. I got it wrong myself but the majority of my class ( and they're very smart ) said that it was Calcium. I hope that was the question you meant!
