Any one did p52 today?

 

[fourtris46]

I didnt know the nernst eqn part........that part just messed me up and the distialltion shit.......i didnt know wht to drw

same!! I even messed up the charge of Mn and the % yield

 

[FaDGus]

Anyone did 21?

I did paper 21, was the paper easy or hard for you?

 

[Maiday Holsey]

I did p21, it was ok, but I made some dumb mistakes. You?

 

[FaDGus]

The paper was really easy. Which questions did you mess up in?

 

[Maiday Holsey]

In the first question where we were supposed to write everything in terms of X, i used copper (Cu) instead.

 

[FaDGus]

That's fine, just do good in tomorrows paper 31

 

[Maiday Holsey]

I'm doing p32 on 28th. Do you think if they're gonna accept that?

 

[FaDGus]

Not really, since they clearly mentioned that write in terms of X.

 

[Maiday Holsey]

Ugh ok thanks.

What was the mass of Cl2 in the ideal gas equation?

 

[FaDGus]

Its was 0.2 something

 

[Maiday Holsey]

Yess 0.23... and the number of particles? 1.96*10^21 ?

 

[Agestone]

Is anyone giving paper 34????(Any idea what's coming,please help would be really nice i messed up my paper 2)

 

[FaDGus]

Yep, the number of particles was 1.96 x 10^21

 

[blymphocytes]

same!! I even messed up the charge of Mn and the % yield

Omg samee......i got some huge ass valuee

 

[blymphocytes]

I

dk.....i didnt know some explanations, but it was ok compared to last year

[blymphocytes]

h

That's fine, just do good in tomorrows paper 31

ey....do you know what might come btw?

 

[Maiday Holsey]

I used 70 grams per mole for the chlorine molecule. Is that acceptable?

P.S. The number of significant figures wasn't specified anywhere.
