h0w waz the CHEM MCQ paper ???

[kanz123]

hey wt ws the enthalpy chnge of formation...the choices were i guess..-401.5 , +405.1 ,-201 sumthng nd + 201. sumthng...???
did we have to divide by 2 or nottt ???

 

[wonderland]

i got -202

 

[angelgurl]

variant?

 

[sweetiepie]

11 i think as i gave 12 so dix wasnt da value..

 

[wonderland]

So what was the value sweetiepie :Rose: lol

 

[hassam]

+720 in 12

 

[kanz123]

hmm myn waz + 202.1... ...umm i thnk myn's ryt
yea variant 1 i gues "11""

 

[wonderland]

unfortunately , sweetiepie i have given the varient paper 11 .. thus , i am not lucky as you ... all they feel quick well about my paper..hmm i have done it moderately... ardon:

 

[wonderland]

kanz123 .......perphap i wrote -202... would you mind explaining me .. :twisted:

 

[kanz123]

hmmm ..lets see

 

[wonderland]

mr kanz123 what to see ... proof right away if you are not perhaps a falsifier... :Bravo: 8)

 

[kanz123]

umm se in the bond formin of x + x ---> X2 (here its in the products side)
nd in the enthalpy chng eof reaction x2 + xH6 ----> guves sumthng dun rememba ( here X2 is in the reactants side)...so i chnged the sign
before i too got it as -201 ...dats wt my tchr has taught me

BTW ITS *MISS

 

[sweetiepie]

@wonderland wat hassam said was da answer ya so trueee....

 

[wonderland]
