Guys i will eat then i will come back
PlZ join me

 

[♣♠ Magnanimous ♣♠]

C

yeah! i too thought C coz volume is directly proportional to temperature na so if temp doubles than volume will obviously double
kitkat <3 :P why was your answer B?

 

[♣♠ Magnanimous ♣♠]

link please! i will try to solve coz i am not perfect in chem

C

3 is wrong cause we take kelvin ans so
the temperature is not doubled in that case ans so the pressure isnt
1 makes a lot sense why sdid you think it is wrong?

Thank u
inshallah
But this mark is out of 130 :s not 140 ..... Also i expect a high Gt for P21 cuz there was no much of Organic chemistry
IDK how they calculate it
But plz remember me in ur prayers
Good luck to u
Allah kareem

Ya this time everyone expects a higher gt bcz of the very easy p21
Ya will surely remember u in prayers u too remember me
U too pr

got it thanks

Guys could u give me a tip on how to locate that whether there is a chiral carbon in any structure because I never understand that

i thought they are inversely propotional

i thought they are inversely propotional

are nahi asma! see if you have that orange book i mean new edition wali
than see page 77 observe figure 5.2 and 5.3 you will get

Guys could u give me a tip on how to locate that whether there is a chiral carbon in any structure because I never understand that

remove all the carbons with double bond or CX2 or CX3
X might be H or many be just Cl...
you will be left with very less carbon wont take much time try too expand them and see

ZaqZainab help us coz me too don't know about it

If it said 100K to 200K then it would be

gimme an example coz i didn't get anything
