i am sure

asked my teacher

and moreoever p1 was tricky it was p2 which was easier..
i did many probs in p1...

haha^ P2 was easy!! as if!

got 40/40 in P1 inshallah!
P2 was total equalizer for P1 and P6!

i ruined the p1

but will IA score well in p2

best of luck to you..

A person just supports a mass of 20 kg suspended from a rope.

What is the resultant force acting on the mass?

So all done with Biology, time to shift gears for Chemistry ATP.
Though it is easy, but this time the pattern's changed(paper of marks 60 instead of 30 with SAME weight-age) so Chances are high for new out of world inclusions with same old SALT TEST and MOLES question!
Be prepared fellows Paper-4 is going to shackle few from scoring!
Best of Luck!
Too early i know, but do come up with questions aren't asked in past papers to be confident in the EXAM
!

Mashallah thanks to allah i got A* in chemistry......

 

[daredevil]

thankyou!! are there any specific chapters that i should be preparing?

do titration. learn all moles formulae. go thorugh all the reactions and their requirements (especially catalysts if needed) especially from organic chemistry section.
do salts. especially identification of cations, anion, and gases. learn the solubilities of salts like which salts are soluble. and go through all the investigtions for once like just skim through them and see if there's any points. look for any colours given for compounds like we mostly miss out that Copper Oxide (CuO) is black but its given in the book in an investigation. go through that and u're good to go. i think that's just about it.

u've given ur chem paper already??

I have given my papers last year in nov/dec ....and mashallah got a good result also....

which formula is this
Mass(g/dm3)=Mol(dm3).Mr
how can mass be in g/dm3 ???

 

[Spidey21]

which formula is this
Mass(g/dm3)=Mol(dm3).Mr
how can mass be in g/dm3 ???

mol = mass/ mr

and nope thas for the concentration!!

 

[daredevil]

which formula is this
Mass(g/dm3)=Mol(dm3).Mr
how can mass be in g/dm3 ???

no no no!! u must've read it wrong. it must be this way:
Mass(g) = Mol(mol).Mr

even Moles are not in dm3 its in mole.
