It's not balanced.

CURSE U CHEM

Ssshhh ! Chem wil hear that

 

[devilmaycryred]

Guyz , please tell me write answer to nitrogen composition and moles mcq answer ... i wrote higher and equal but now i think it is higher and higher ... coz to find moles of nitrogen in the compound we had to divide the percentage composition by 14 which will give the same result that is higher than ... what are your views ?

[asma tareen]

thats gud for u den

hmmm ^_^

 

[devilmaycryred]

i get a feeling u got that wrong

but what about my reason ... i mean when we find empirecal formula we divide the percentage composition with Ar to find moles ... wasn't the same thing required in that question too ?

3 till now i guess

thats not a prob ... i have also got almost 3-4 wrong scoring 35 in MCQs is gud enuf .. Inshaa Allah, hoping to get around it
