Chemistry P1 and P2 today

[asma tareen]

thats not a prob ... i have also got almost 3-4 wrong scoring 35 in MCQs is gud enuf .. Inshaa Allah, hoping to get around it

hmm hope i'll get that much too

 

[Shadow]

but what about my reason ... i mean when we find empirecal formula we divide the percentage composition with Ar to find moles ... wasn't the same thing required in that question too ?

Nope, ques said bout mols of NITROGEN only ... they were same in both formulae ...

Nope, ques said bout mols of NITROGEN

I checked a question from the past papers (theory) in which two compounds had the same number of atoms of Nitrogen in it but different number of moles.

 

[devilmaycryred]

yes

Nope, ques said bout mols of NITROGEN only ... they were same in both formulae ...

and to find moles of nitrogen we had to divide percentage composition of nitrogen by Ar of nitrogen ... what do you think ?

Diff no of mols or diff no of mols of NITROGEN?

[Kinza Zimri]

Who is Imran merchant? He predicts omlevelmpapers or that of matric?

hes a chemistry teacher of o levels, a day before the exam he tells exactly what is going to come, no one knows how he gets to know the whole paper

 

[Saad Mughal]

P1 or P2?

P2.

 

[Shadow]

he's a mystery

 

[Shadow]

P2.

N06 B7 (d) it is ... they asked bout the % of nitrogen in both fertilizers, not the moles

 

[ritx]

he's a mystery

does any one personally know any of his students?
