Chem P51 How was it?.

[Otaiba13]

hey guys so what did u all think about chem p51 i found it a little lengthy and a bit difficult i was rushed for time at the end !!,

 

[earthling]

It was a simple paper...very easy...but I messed up question one!!! Might not even get 5/15 in that one.
Hopefully, threshold's lower???

 

[sweetyrox]

It was bad exPected threshold?

 

[larina]

yes it was a very easy paper...but i messed up queation 1!! there was so little space given

Exactly!!! and I didn't even know what to write for the table, as I did not understand the question!

 

[Otaiba13]

Yeah why the hell didnt they give us lines ??

 

[larina]

i used water to change the concentration and so did my friends :S
anddd i expect the threshold to be around 19-21!!

 

[larina]

Yeah why the hell didnt they give us lines ??

OMG were we supposed to draw stuff?? i just wrote

 

[Otaiba13]

No no we didnt have to draw anything but i wud have if i had time or any space

 

[larina]

No no we didnt have to draw anything but i wud have if i had time or any space

AND THERE WERE NO BLANK PAGES!!
what do u expect the threshold to be???

Can it go lower than 19???

 

[Otaiba13]

For q1 heres what i did
Dissolved a calculated mass in water, poured in volumetric flask, brought up to 250cm3, used different volumes of this to make different conc of cuso4 using different volumes of water

 

[larina]

Can it go lower than 19???

umm maybe?! for jun 2011 it was 20 and it was easier than this one, so it can be lower than 19 i think...
how was ur paper?

i did something like that tooo, i kept the final volume constant, and varied volumes of water and CuSO4, but the thing is that there was no water given!!

 

[Otaiba13]

Hmm thats not a problem they dont always write water unless they want to specify volume water comes under standard laboratory apparatus!!

yay!
and what was ur gradient?

 

[Otaiba13]

0.0871

 

[sweetyrox]

Wat anomalous points did u guyx get?

 

[larina]

i got 0.088

 

[larina]

Wat anomalous points did u guyx get?

3 and 7!! as far as i remember..
