So guys...............how was it

 

[ALevel96]

Really good! Paper was soo easy

 

[blossom edward]

just okay....an average paper :/

 

[Sherlock.]

I have many questions.
1)Where does the color go(purple/green)
2)Which ones were isoelectronic
3)What is sodium carbonate used for in cooking
4)Which moles were we supposed to use in the Hess's cycle

no idea abt 1 and 2 as myslef im confused....likin for 3rd one i think its used as baking soda...and 4th i dont remember..
btw wat was the enthalpy change?????

guys please tell me was the last question the organic reaction one? with cracking and stuff? or did i skip a question!? D:

 

[cardude456]

it cracked to give C2H4 and C10H22

 

[blossom edward]

it cracked to give C2H4 and C10H22

i guess she got the reply on the other thread...nevermind..its never too late

I got -400 something...:-? Wbu?

 

[cardude456]

what...........??? i got - 115!!!

 

[DC1313]

what...........??? i got - 115!!!

i got that too

 

[Choco<3]

what...........??? i got - 115!!!

Are you talking about part A or part b??

 

[Zahidur]

It is -115 as the mass of the solution (25cm^3) was supposed to be taken.

Are you people talking about the hess's cycle or the part A?.

I make silly mistakes every freakin time.. I dnt remember a thing..what was the first question?? Oo and what was the percentage yield.??

Jan 2013 was better..

How was Jan 2013 better.....that was the worst chemistry as paper ever made!!!!!!

Somehow managed to score a B in jan...am not even gonna get a C this time..:'(.. Wht was the percentage yield??
