Can someone tell me apart from dispersion force are there any more inter molecular forces on iodine mono chloride? And how did you guys drew the LCL3 ?
ICl, has additional permanent dipole dipole forces, also it's electron number is greater. etc etc
ICl3 was like this, as Iodine can expand its d orbital accomodating more then 8 in valence.
but the answer is 0.17 mol of Br2 and 0.33 mol of I2
Ahh crap. I'm definitely losing a lot of marks in section C. Since I'm a private candidate, I didn't get to talk to anyone about their paper. But do you know how it was for other people?

About 15 gave from my centre, they found the paper to be of slight hard difficulty.

Dont worry my exam was pretty crap. Section C and then a few of Section B. You want to discuss them?
What was the question regarding the Ionic equation? on the 2nd page of section C, i forgot.
It was the equation for potassium iodide and sulfuric acid. and then you had to give an ionic equation on how sulfur is produced from H2SO4. BUT then i went and looked in my book after the exam, and suprisingly it said that the equation of KI and H2SO4 is not required for A-Level, so my teacher is submitting a complaint. Did you get the dot and cross diagram for ICL3 right? and what about that question of the preparation of the CACO3 from CaOH?

Well for me section B was pretty good except I might've messed up the CaCO3 decomposition question a bit. Section C started off fine but then the rest of the questions were weird. I really think we should leave this here & focus on the remaining ones! haha Fingers crossed! Hope the curve is good

Ive got only my unit 3 left, fingers crossed for that one

Yes, I got the ICl3 right, i posted above.
For the ionic equation, i wrote this:
H2SO4 + 6H+ + 6e- --> 4H2O + S
---
Prep of slaked lime (Ca(OH2) from CaCO3 (Two stages)
I wrote, CaCO3 --> CaO + CO2 and CaO + H2O --> Ca(OH)2 and high temp condition etc.
Oh same! Since this unit is all based on Unit 1 & 2 practicals, I couldn't find any sort of revision notes for this. How are you revising?
I studied for it last year, im just re sitting it as i got a B, and im trying to get a higher grade. I studied from the Unit 3 & & edexcel book. But I did notes on them, if you want them, they're hand written though :/ Any questions i can help you wit, as i have a bit of experience on it
