yah i m

buddy if you got any notes,do link me up with them

 

[yousef0074]

Are the improvements I mentioned reasonable?

 

[shoaeb]

no physics is the only science im not sitting for! more time for me to study! but gd luck if u take it

oh allright,thanks
goodluck to you too!

For the improvements I wrote : weigh the crucible immediately after heating and second one was to remove the crucible, then add the hydrated solid and place it back on the balance incase of spillage won't fall on balance. So this is a more accurate way of fInding the mass. I got x to be 2.3. Are these answers reasonable?

haha yousef..the threshold will tell us about these
and the x was 2.3 ..thats what i got first..but then some stupidity in me made me change it to 3.7 :| how dumb
and these dont really make sense :$

 

[yousef0074]

what are they that don't make sense? the improvements?

thanks alot yousef!

what do you predict the minimum mark for an A to be for today's paper?

 

[Cuteangel]

delta H1 was +30 kj/mol
delta H2 was - 34 kj/ mol
delta Hr was = delta H1 - delta H2
= 30 - (-34) = 64 kj/mol

still didnt get how u got 64 :S

 

[shoaeb]

n

what do you predict the minimum mark for an A to be for today's paper?

no idea yousef..people in my centre said it was kinda easy..

 

[U stalking ME]

still didnt get how u got 64 :S

its okay, i got how i did it and dude chill, its the wrong ans!!

 

[Basherath]

it was
+94Kj/mol coz the =30 was supposed to be multiplied by 2.

Y multiply by 2????
