Hello all,

Trying to balance the symbol equation of Hydrochloric acid + Iron (II) Oxide

HCl + FeO --> H2O + Cl3Fe

But i just can't get it to balance?!

Either im incredibly stupid or its impossible (im going for the former!)

This is driving me crazy... it should be piss easy!

I don't think it can work. Are you sure your equation is right?

Well thats what im starting to think.

The question specifically says Hydrochloric acid + Iron (II) Oxide. Have i got the formulas wrong? Or is it a typo? Would Iron (III) Oxide work?

Impossible.

cba to concentrate more, but it seems impossible.

Doesn't seem to work quite right, no matter what value I put in.

You need 3 times more I's than C's, and you can only get that from HCI, so I don't think it can work.

6HCl + Fe2O3 -> 3H2O + 2Cl3Fe does work so it's probably Iron(III) oxide, I think. has been a long time though

I can't figure it out. I'm no genius, but I remember being able to get through this stuff pretty quickly when I took chemistry. Just out of curiosity, what level of chemistry is this?

H2O + Cl3Fe > HCl + FeO

Trick question? OMG, it's been so long since I took chemistry...so don't take my word for it. Time to crack open the ol' book again before I forget it all.

[edit: Wait, no, that's half-cell. Silly me.]

Thanks guys... stupid question sheet made me feel all retarted.

EDIT: This is AS Chemistry btw, who ever asked.

I thought you had to multiply all the letters with the same number? (lol, simplicity ftw)

Fe2O3 can't be the same as FeO, can it?

=Karma-Kills=: "Don't post while intoxicated."; +356|6839|England

No, FeO is different from Fe2O3.
FeO is Iron (II) Oxide, Fe2O3 is Iron (III) oxide - wherein i believe the mistake in the question lies.

Update to my last post: I think this problem is unsolvable by balance, at least the way it's written. I even ran it through my software after it stumped me on paper.

Are you using Iron II or Iron III because the question and equation say two different things

If the question is right then it is

4HCl + 2FeO --> 2H2O + 2Cl2Fe

Geeze, the correct reaction is actually (obtained from http://www.ucc.ie/academic/chem/dolchem … p/hcl.html)

FeO + 2 HCl ---> FeCl₂ + H₂O

Note how O has a valence of -2, while Cl is -1. Looking at the molecule FeO, it must be Iron [II]. Therefore there are 2 Cl's that can bond with the Fe, not the 3 that your eqn has.

Let me tell you why this will never balance. Since your product is water, you'll always need twice as much HCl than FeO, but looking at Cl3Fe, you'll need 3 times as much HCl than FeO, which is a direct contradiction. So perhaps check up on whether or not the question is right because your thing will never balance.

Nope, they teach it in Denmark.. I learned it when I had chemestry at Technical Collage (htx)... but thats 2-3 years ago and I cant remember much of it cause I havet used since..

Yeah, but they can remember it,, and i doubt they are all in the middle of an education similar to HTX right now...

Iron (III) oxide is not FeO, its Fe2O3... so the equation must be:

Fe2O3+6HCl -------> 2FeCl3+ 3H2O

You can't balance because the oxidation numbers aren't right. "O" has an oxidation number of -2, "Cl" is -1. If FeO is Iron (II) Oxide, you need to have 2 "Cl," not 3.

Balanced Equation should be 2HCl + FeO ---> H₂O + FeCl₂
