Here are the answers:
You solved the question?
I’ll try now. Will post if I get them
Pls try this
N factor answer is wrong
It must be A acc to me
Why did you divide by 0.95? 1 mole of that compound has 0.85 Fe+2
Let's take 1 molecule of the compound
So it has total 0.95 molecules Fe
Out of this 0.85 is +2 and 0.10 is +3.
Yes. So n factor is no of electrons transferred per mole of that compound. So its just 0.85/1. Right?
Correct. My bad. LOL.
Any progress with the other question?
When I tried forming two equations for amount of oxygen and Fe3+ I get equations of two parallel lines.
No bro not trying right now.
I'm revising some chaps. I'll try at late night. Question seems interesting though.
Did you try this one? After seeing this problem, I think I should go back and start learning stoichiometry from the beginning again.
Sorry bro. Not getting this. Lets wait for others to try.
@Azimuddin_Sheikh @pratyaksh_tyagi @Siddharth_M @seshu_ram
I'll try at 2:00 or tomorrow.
Ok bro. Please do.
Ikr! I tried bro, didn't get it, so didn't say anything.
I'll try tomorrow again, maybe after a bit of revising. Stoichiometry has never been a strong point for me, though. @Viraam_Rao
Guys, all the answers are 100% correct. There's no error in those.
This question is the reason why I hate Bansal's rank booster.
Yes bro got it, read the following posts after the one I claimed its wrong. Viram Rao resolved the mistake I was doing.
And sorry I didn't try the others till now. Will surely post if I try and can actually solve.
Any easy way to find number of moles of oxygen needed in fecr2o4 reaction ?? @Viraam_Rao can anyone show by nfactor method ?? Then I can get the answer for rest three easily .
Also n factor of O2 can anyone tell how to get in the second reaction too ?? ( I got it by balancing method)
