Chemistry unit 1 6CH01 Discussion! :)

yh might be...chem boundaries r usually high....

Plus this paper was actually relatively easy, so....

55- A my word !

LOL i want it to be 50 an A

may be 58

whoa whoa come down dude!!!

I'm actually worried it might even be as high as 60 :/

nah wont be that much.... will be in the range og 50-55 or even 45-55 to be A... hope so...

Mcqs were tricky a bit !
the proton question which element did u write? i wrote xenon?
hess law answer was + 97 KJ mol-1 !
yield was 53-54%
why hydrogencarbonate was used i wrote neutralises teh acid :/
which has highest inoization energy i wrote bromine !

i think the highest i.e is krypton as it is a noble gas....yield was 54%.....but was the energy and enthalpy change???

dont scare me!!!

umm well lets just wait to see what everyone has to say about it!>...

yayyyy!!! i wrote krypton tooo!!!! whooo!! n i couldnt do enthalpy though i was worryd abt the qstns aftr em like hess law n stuff!!

in question 22 there was a question about carbon bonds may be....i drew the p-orbitals and shown pi and sigma bonds is it okay?

unit 2 should be easy.... todays papr makes me think it so!... wat do u say?

Krypton ftw

yeah me too....too much worried about hess law this time.....

 

[Manasa]

Krypton ftw

hehehhe yhh!!!.... wat did u write for the 3 qstns that were above it where it said with the 1st i.e n all... ?

unit 2 should be easy.... todays papr makes me think it so!... wat do u say?

I can't really tell :/ The thing about unit 2 is there's so much more content in it. So many mechanism and stuff that we have to know. Not big fan of unit 2 but lets just hope to god they have mercy on us..

i want it to be in the 40s.....

yhhh which way was your arrow?

LOL chem as a whole isnt my thing!!!

i want it to be in the 40s.....

OMG!!!! yhhh!!!!>..... now that i think of my answrs..... i really hope its in the 40s.... :/

 

[chathumus]

hehehhe yhh!!!.... wat did u write for the 3 qstns that were above it where it said with the 1st i.e n all... ?

the first; Sereljjendkje whatever is lower because it has a lower proton number so the attraction to the positive nucleas is lower and radius is larger and stuff. So its easier to remove.
I think for K or something I said the shielding effect increases because its in a new subshell.. plus the positive nuclear attraction is lower blahblah

 

[tawsif kaium]

yhhh which way was your arrow?

it was supposed to be up...but i couldn't give the arrow as i wasted lots of time

 

[chathumus]

yhhh which way was your arrow?

both arrows were downwards yeah? please tell me yes? :O

 

[tawsif kaium]

both arrows were downwards yeah? please tell me yes? :O

it was a simple hess's law diagram so up
