So how was chemistry P12 today?

[dumb human]

Yup, chiral centers were 7.
Na2O+SO3=Na2SO4 option D that's what I did

i spend 3 minutes on this question and still wrong :'(

I'm pretty sure of the chiral centers but not about the other one.
Anyways the volume of remaining gases was 18.0, right?

i dont knw I SUCK...

 

[unkidd]

Chiral 4 or 6 most people had it as answer

18 I got 7.2

It was 0.1 mole if oxygen and 0.3 moles of the products each dont remember the answer tho

Didn't it say neutralization. Sodium oxide would form nahso4 and h20 and I couldn't get that but I did get na2hpo4 and h20 fir phosphoric acid and sodium oxide

 

[Kamihus]

Why

18 I got 7.2

16.8 was of products and 1.2 of oxygen, well that's what I got

It was 0.1 mole if oxygen and 0.3 moles of the products each dont remember the answer tho

As I said before I'm not so sure about this one.

 

[Princess Raven]

Yea the ratio was 1:5 so the moles of oxygen was o.5 using that u get volume and that was 12 exactly and in the question it said 12 is required to react completely so none in left over then u use the ratio between the hydrocarbon and co2 which was 1:3 I think and u get 0.3 so the volume left is 7.2.. Or atleast that's what I did

I dunno about that either but I think you're right about na2o and sulfuric acid. Ugh I was hoping to get above 38 in p1 cause that's the only way I could balance my grade! I completely messed up the practical and p2

 

[Princess Raven]

I put D for the na2o too

[Kamihus]

What about the first in section B, the viscous one? A or B?
Ammonia one was D as it did not react as a base?

The viscous was A I know for sure coz my teacher told me and yes the ammonia one was d too what about the bond energy question 315 or 351 and the one about kp I just guessed A I think it was 5.76 or something

The Kp one yes it was 5.37 or something like that.
Couldnt do the bond energy and wrote 351

 

[Princess Raven]

The Kp one yes it was 5.37 or something like that.
Couldnt do the bond energy and wrote 351

Same!!! Lol I guessed 351 but a lot of ppl said it was 315 don't know

 

[Princess Raven]

Any others u rmr?

 

[Kamihus]

The di-ester would be formed and was something OCO?
And the HX graph question was surely A

 

[Princess Raven]

For the diester ya I think I got something with that and what HX graph? And what about the one that have electro negativity as x axis and melting point at y axis I chose B

Yup B was right in that one
HX graph in which was from Group 7, peak was at B of ionization energies so previous one was correct

 

[Princess Raven]

Ohh that one ya it was A
