It's there in the new bookWhere to study these topics from? :/
I can send pics if u need

Then why not D?
It's says B as the answer.The answer is D. Two pie orbitals opting for sideways overlapping.
Formation of ICl3 (s):
Oxidation number of N in:
Only B shows a p orbital.
p orbitals
Formation of ICl3 (s):
1/2 I2 (s) + 3/2Cl2(g) --> ICl3(s)
2 x Formation of ICl3 (s) :
I2(s) + 3Cl2(g) --> 2ICl3(s)
How to do this?
Easy.
Atomize: I2(s) ---> I2(g) [+38]
React: I2(g) + 3Cl2(g) ---> 2ICl3 (s) [-214]
Total = 38 - 214 = -176kJ
But this was 2 x Formation of ICl3(s)
So divide it by 2. -176/2 = -88kJ/mol
Jazak Allah KhairanOxidation number of N in:
NH4+ : -3
NO3- : +5
N2O : +1
So change from NH4+ to N2O is +4
And change from NO3- to N2O is -4
Bring it onJazak Allah Khairan
You're a life saver!!!
I still have a few more doubts,If possible can you please solve them............
X is not a strong acid. The pH is only 6.
CaCO3 and Ca(OH)2 both react with acids. KNO3 is a salt. It is a result of neutralisation, not a reagent.
NO can be oxidised to NO2 in the atmosphere pretty easily. SO2 can also be oxidised to SO3, especially since NO catalyses this reaction.
Iodoform test I think A2 questions should be pretty much similar to the AS ones.So the 2016 syllabus for AS has somethings moved from A2 to As, namely carbon nanotubes and Buckminsterfullerene, infrared spectroscopy and iodofrom test. I have no where to practice questions from these so could anybody link some A2 papers having questions from these topics. Cheers

Unfortunately, CO is quite stable and won't turn into CO2 in the atmosphere. If that was the case, we wouldn't be complaining about CO, since it would be naturally depleted. Only the CO2 produced would be an issue due to global warming.
Oxidation of NO and SO2 to form NO2 and SO3 respectively doesn't solve any problems, since it still forms acid rain and weathers the buildings and destructs aquatic life.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
