Hello,

May I ask why in IO3‾  +  5 I‾  + 6 H+ ↔ 2 I2 +  3 H2O    there are 2 moles of I2 ? Actually, it has to be 5, but because of the index 2 it has to be 2,5  , isnt it ?


Kind regards

Hello,

May I ask why in IO3‾  +  5 I‾  + 6 H+ ↔ 2 I2 +  3 H2O 

This reaction isn't balanced.  Dunno where you got it, but its wrong.  Please don't tell me its what a teacher gave or what the textbook problem said, because its still wrong.  Take the initiative to balance it before wondering what else might possibly be wrong.

  there are 2 moles of I2 ?

Cause its wrong.

Actually, it has to be 5,

Also incorrect.

but because of the index 2 it has to be 2,5  , isnt it ?

Also incorrect.  Also, I don't know what you mean by index in this sense.  Also, although we sometimes use fractional numbers to make balancing easier, its not needed in this case.

Kind regards

IO3‾  +   I‾  + 6 H+ ↔  I2 +  3 H2O
 

=> This is right, isnt it ?

[peterschmidt3943]

and yes, this is what a PROFESSOR wrote!!

That's balanced, that doesn't mean the reaction happens that way

[peterschmidt3943]

why?

[Borek]

IO3‾  +   I‾  + 6 H+ ↔  I2 +  3 H2O

Sorry, but that's not balanced either.

Your first equation was much closer to the reality, it contained just a single simple mistake.

Even then, just because the reaction is balanced doesn't mean it happens. Being balanced is a necessary, but not sufficient condition.

IO3‾  +  5 I‾  + 6 H+ ↔ 2 I2 +  3 H2O,

=>so, on the right hand side it has to be three then, isnt it? I guess that because of the fact that we got 2,5, we have to round it up to 3... the equation would be balanced then..

Pure nonsense. Do you understand what it means for the reaction to be balanced?

[peterschmidt3943]

yes, that and the fact that we got 6 I on the right and left side..

Its poor form to say "My teacher is a dummy and look at this..." or "My textbook is written by idiots because I know thermodynamics better than anyone ..." or things of that nature.

I specifically told you NOT to do that, in this thread, because I expected you to do that.

And you specifically did that, in this thread.

This thread is locked, before it becomes a multi page thread, with you posting nothing but "Why?"  or remaking posts that have already been corrected.

Write out all of your work and the reasons behind it in one posting.  Don't lengthen a thread with random posts:

"Is this it?"


"How 'bout now?"


Instead, build your answers using what's been posted.  When we ask a question, answer it, and then say how it helps you solve the problem, or "That doesn't help answer my question because what I see is ..."  and we'll all keep moving forward.
