How was your chemistry p5 ?

[donorsolutions]

i

If I quote figures that I used, will it be a violation of the rules?
Elsewise, yes, but I used the C1V1 = C2V2 formula

i too used the same formula and then determined how much volume of water has to be added that brings the hcl to the required concentration.(whicch neutralizes calcium hyroxide at the same volume )... thanks for replying

I used c1v1 = c2v2 too.
I changed the value of HCl's conc.
Made a small graph showing 2, 1.8, 1.6 and so on values.
I did blunders in this part. :s

Hey guys! How did you guys drew the graph of Q1?

 

[stella jazz]

i dunno if its allowed 2 ask yet...but in q1 the 1st ques the solubility decreases rite?

 

[donorsolutions]

I guess the question had too many points to be mentioned (considering that I used the whole blank page number 7 as well ) So marks can be scooped up easily.

yes i also filled the whole page .it demanded too much detail and calculation!

yes it does. but i didnt know how to make the graph.

yes it does. but i didnt know how to make the graph.

I drew an increasing curve till 25 deg, then decreased it. That was the way it was supposed to be!

Why the increasing curve?
I guess it was just a decreasing straight line.

i got a 78 in As and in this paper i think i wil get around 22-23, how much do i need to get in paper 4 to get an overall A? i would be very glad if someone cleared this for me

i think you need near about 65-70(probably) to get A in aggreate.

 

[kazi umayer]

It would be around 20-ish
Guys i could nt draw the graph and calculated gradient from the table
And told about anamolie
Will i be able to get few marks?

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

 

[Resha rimaz]

God Im shocked abt ur comments. For me ques 1 ws simply HORID!!!!!!!!!!!!!!!!!!

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

 

[Optimass25]

guys what was da gradient...?
mine 4.8... nd we know it frm before dat CuSO4 has 5 molecules of water wit it... so i think gradient shud be nearly 5...

 

[Daisy_94]

How did u guys dilute hcl, messed up tht part

 

[Daisy_94]

And what was ur label in y and x axis ?

 

[abdulmoizmehmood]

what about the gradient ppl?

 

[Daisy_94]

4.75 ?

 

[abdulmoizmehmood]

How did u guys dilute hcl, messed up tht part

took 10 cm3 of hcl and added 40 water total 50,,,
50 kz my other volume was 50...

 

[abdulmoizmehmood]

mine was 4... and the value of x

4.75 ?

?

 

[Daisy_94]

The gradient
