Thanks .
By the way, what is this formula P2/T1=P3/T2.:confused:
Can you tell me. :unsure:
Thanks again
You 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 :p1V1=P2V2, P1/T1 = P2/T2, P1V1/T1 = P2V2/T2

Its pretty simply if you can understand the relationship!!!:D:D:D

hope that helps:)

Thankyou but, I know this equation its just that I don't think it's working on that question..( I was getting a wrong answer).

36 When the yellow liquid NCl3 is stirred into aqueous sodium hydroxide, the reaction that occurs
can be represented by the following equation.
2NCl3(l) + 6NaOH(aq) → N2(g) + 3NaCl (aq) + 3NaOCl (aq) + 3H2O(l)
What will be the result of this reaction?
1 The nitrogen is oxidised.
2 A bleaching solution remains after the reaction.
3 The final solution gives a precipitate with acidified silver nitrate.

why is 1) not correct

The ox.no of N in NCl3 is +3 and in N2 it is 0
change in ox.no=3 so N has GAINED 3 electrons so it's been reduced and that's why 1 is not correct and hence C is the right answer

But Nitrogen is more electronegative than chlorine so shouldn't Nitrogen be -3 and Chlorine be +1 (Br<Cl<N<O<F)
