i am expecting 45/60 do i still have a chance to get A??

anythng above 42- 44 is ok which i guess is the general threshold

 

[muhammad05]

Alhamdulliah it wasn't as bad as expected. I expected freaking organic all over the place and hybridization. I'm worried about p1 now...

 

[Browny]

Can anyone tell me the weightage for P1 and P4 for mathematics?

 

[muhammad05]

60:40

 

[Browny]

60:40

What is 60 and what is 40?

 

[Snowysangel]

What was the value of x??

 

[Browny]

For the practical paper can we get to test for gases other than NH3 and how to test for them?

 

[zain ul abidin]

x=2

 

[Mohammed salik]

[cosmicT]

Can someone give me an estimated grade threshold for the current (2014) chemistry paper 2

 

[EmiraS]

I got x=1, what about you?

 

[Logitech]

Does anyone have any idea about the questions for p31 practical ?

 

[Snowysangel]

x=2

But wasnt the no of moles of the compound = 6.3/0.01, since there were 0.05/5=0.01 moles of it

 

[Snowysangel]

x=2

How did you calculate the molar mass of the compound?
