THANK YOUBF3 bcos of the electronegative difference
thanksYou just need to understand these:
Pressure is DIRECTLY PROPORTIONAL to Temperature p=nt
Pressure is INDIRECTLY PROPORTIONAL to volume p=n/v where n is a constant
from there you derive the equations 1V1=P2V2, P1/T1 = P2/T2, P1V1/T1 = P2V2/T2
Its pretty simply if you can understand the relationship!!!
hope that helps
Nitrogen atom has two lone pairs and one single electron in it (N atomic no. 7 )Anyone????
Thank you very much amina1300 .View attachment 62368
ONLY THE LAST ONE CANCELS OUT.
Q10 Ans = CPlease anyone?
"N" + ½O2 → NO nitric oxide (gas)
Yeah you're right, thank you very much!"N" + ½O2 → NO nitric oxide (gas)
NO + ½O2 →fast→ NO2 nitrogen dioxide
NO is diatomic
And it is polar as it contains electro-negative N
I think A is correct .... ?
How do you know that what will form ..can you explain in detail? :/ I'm really bad at Organic Chemistry.For q. 37
1 will react to form propanone and 2-methyl propanoic acid
2 will also form a Carboxyllic aid and a ketone
3.will also for a carboxyllic acid and a ketone
so I suppose its A?
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.
