Anybody remembers the value for 'X'? Water? And what was ionic equation? The one we had to balance.

x=2

 

[Princess Raven]

the answer to the abundance is 45% and 55%

 

[Tulaib]

the answer to the abundance is 45% and 55%

you must have used exactly 79 and 81 instead of 78.92 and 80.92 given in the paper, that is wrong

 

[mohammad hurani]

are you guys discussing paper 21 or 22 ?

 

[Batguy]

i screwed in chemistry exam!! relative abundace wrong value of X wrong. one angle wrong one explaination wrong!!! that was so easy paper if i havent prepared organic that much!!! study whole year like never before, gets olevels mole question gets effed :''|

 

[Batguy]

curse these exams

What was to be written in that four mark part, the observation in the last question? I wrote it is an alkene and a ketone is formed but it was of four marks so what further was to be written. Please answer this.

How was x 2? It was 30! Why did everyone use .05 moles of the compound? We had to divide it by 5 necause we only used 1 relative mole of the compound instead of the 5 that was given in the equation. So 0.05/5= .01....6.3/0.01= 630...630-90/18=30

 

[Snowysangel]

I could be wrong though...but it doesn't make sense why we would have used .05 moles of he compound

 

[mohammad hurani]

which paper are u discussing guys please someone answer

I dont remember the statement now, but everyone in my class calculated x=2

Hey
I guess I'm late now but I've started a site with solved papers that could have helped you prepare for chemistry. But that's ok, if any of you take physics or Math, I've got those papers too. Please check out my site, it'll mean a lot to me!
