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???

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..

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

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 :)
