Physics n Chemistry Unit 6 IAL exam discussion (How was the paper ?)

[Paras]

Paras Hadi Murtaza please no discussion for 24 hours!!

dude! i said for chem! not physics

 

[Hadi Murtaza]

Yessssssssssssssssssss! Do u have any notes on Chemistry IAL Paper 1! Its on 23rd may!

I do

 

[shahlakh]

It was hmm I can't remember, probably 13%

Wait hold on was it really 13%??? Are u sure??? and wait which percentage difference?? I forgot everything

Difference between 0,157 and your concentration of Fe2+

 

[urwahboy]

wasnt really 13 it kinda rounded of to 14%... chem paper was way easier than physics... especially the K thing... well not discussing it just saying :/

 

[shahlakh]

:O what did I do.....arent u talking abt the one in which there was like a value 0.157 as conce

Difference between 0,157 and your concentration of Fe2+

ntration.....???


What was ur value for fe2+ concentration?? do u remember??

 

[Mufaddal]

wow!! the physics paper was a relief! way better than chem..chem just freaks me out!

I think I had 0.136

guys in the last question, will they cut marks for the y-axes lnR being in kΩ ? I did not convert it to Ω and started from -0.20.. Also, what did you say in the thermistor decreasing resistance with increasing temperature?

 

[husain barood]

it was 0.134 or something close to that..and the percentage difference wwas around 14%.
overall chem was easier than the rest.

 

[tawsif kaium]

how many titre did u guys take 2 or 3??

 

[Hadi Murtaza]

how many titre did u guys take 2 or 3??

No they wont

 

[Hadi Murtaza]

yahh dats da correct value

 

[husain barood]

it was 0.134 or something close to that..and the percentage difference wwas around 14%.

it was 2 as you only take titre which are in the range of 0.1. so you would take 22.4 and 22.3 and the mean would be 22.35

yes it was 2 titres....what was the percentage difference?

 

[husain barood]

yes it was 2 titres....what was the percentage difference?

well the percentage difference was around 14%

 

[tawsif kaium]

well the percentage difference was around 14%

what was the accepted value given???...i can't remember :/

 

[husain barood]

what was the accepted value given???...i can't remember :/

0.157 it would be ((0.157-0.136)/0.157)*100.
i am not sure about 0.136. it was around this

 

[Hadi Murtaza]

0.157 it would be ((0.157-0.136)/0.157)*100.

Its correct
