How was your chemistry p5 ?

[scarface007]

Yah it was hard! How much are you expecting to get?

idk i messed it all up, couldnt finish Q1 and messed up Q2 coz of wrong moles of water formed :/
i will be fortunate if i get 12 or 13

wbu?

Phew!! The second question well and good, but the first one was horrible!!! Never has there been a question for EIGHT marks!!

What moles of water?
I think Q1 was relatively better... hoping to get above 20..
And IsA you'll get higher than what you're expecting!

how can you get a slope of a curve??

no i just took gradient for a straight line in my plot,
i said my i got curve after mols turns to 10-2(0.01)
straight line until 10-3(0.001)

Just wondering - how exactly is an A* calculated
Is it high As in all papers
or total marks across all components [which you can calculate from the second page of gt?]

I got straight line for question 2 variant 51.my gradient was 6.92.
HOw much x did you guys got?
I did this.. I got gradient as 6.92.
the question asked us to find x i.e the moles of water.
the ration of water to feso4 was 6.92:1.
now find their empirical formula.you will get 58 which is x.

and I did not mention starch as an indicator.I really missed up in question 1.Hope I get an A*.What concentration of chlorine did you get.there was no time to revise.

is the temperature supposed to vary ?

It was a graph of solubility against temperature if I'm not wrong. Temperature was the independednt variable, so I'd say yes.

yes!.

 

[anushey]

how much was x///?????

 

[saifookhan]

Yes. Var 2.

I hope you guys are talking about variant 2.. Am I right?
Because our paper didn't have any dilutions to be made... (variant 1)

 

[MaxStudentALevel]

same here
I should've done the graph first then everything else
:'(

IKNOW I mean at least we knew how to fully do the graph! That was seriously the best strategy!

 

[MaxStudentALevel]

i feel you man, wasted my time on the first question trying to figure out how to dilute hcl then had little time for q2

I knowwwww I did the EXACT same thing. Although it wasn't difficult just the whole thinking process was time consuming!

I'm pretty sure a combination of the two.
But maybe just total marks, I have no idea!

Chemistry P52 was somewhat easy specially question 2. Q1 planning part was a bit difficult.

it was in question 2, you had to find the moles of water formed and then plot the graph with anhydrous Fe2SO4 on the x axis and moles of water on Y axis..... :/

IKNOW I mean at least we knew how to fully do the graph! That was seriously the best strategy!

most of my friends who did that had only 15 mins to solve the Q1 which required thinking and strategy

girl....7 was the answer i guess....

lmfao...i used universal indicator... forgot that there is a thing called STARCH...xd
messed up the 1st question..

 

[lionkill3r]

In paper 52 i got X as 4.6 but rouneded it off to 4 instead of 5 stupid mistakes ...
