how was chem p41 ??!?! expected thresholds ?!?!

[larina]

Manarat Al Riyadh school ... in Saudi Arabia...

OMG me too lol. r u my classmate?

 

[wonderland]

the first part, right? it was -180!

I think question 2... As they already gave the enthalpy of formation which was something 90... and we had to find enthalpy of formation..

 

[wonderland]

LoL ... Ok

yeah i know, they gav us enthalpy change of formation as +90 and we had to find the enthaply change of REATION... i got it as -180

 

[wonderland]

I am not certain... though .... Are you in the boy section or girl section....

How ?

 

[bestgirl]

in mass spectrometer for propane what was answer for 156,158 and 160??

girls

 

[wonderland]

Ok I am in boys section...

 

[larina]

How ?

enthalpy change of formation of elemenst is always zero. so (0+0)- (2*90) = -180

i just did the first one!
it was CH3CH2CHClBr+ for 156
couldnt do the nxt ones :'(

I am can't recall it ... I am not sure ...

I think 156 was propene, 158 = chlorine , 160 = bromine... Although I am not sure what I wrote....

What was the answer for the group 1v chloride regarding volatility.

umm but the peaks..

 

[wonderland]

Larina ... What was your results in As level.... and have you applied to university

volitality increases down the grp!

 

[m.r92]

Which paper did you guys appear for? I don't remember any question involving volume of hydrogen... Was it paper 42?

 

[larina]

Larina ... What was your results in As level.... and have you applied to university

i got B in AS, with components A in p1, B in P2 and A in p3.
hw abt u??

 

[wonderland]

umm but the peaks..

As I said I don't exactly remember what I wrote....
