message: okay, so we know that Iron Oxide is Fe2O3 ... but whats the actually Balanced Equation????? I know the wording equation (Iron + Oxygene = Iron Oxide), but what is the balanced equation. Fe02 ... but how much of Fe? I cant work it out. I'm a yr9 student, and i really need to know to finnish my corrosion and risting project.

message: Is poop really the term?
the article mentioned a very fine poop used in rouge, but this really didn't make sense to me. Could it be vandalism or am I missing a really technical term?
I substituted "precipitate"

replies: text: No it isn't the term - if you look the previous edit was an anon changing "powder" into "poop".  How hilarious of them, I've never seen anything so funny on Wikipedia before.  If you see something like that, look at the history and check the recent edits - words like "gay" and "poop" or obscenities are nearly always vandalism.  Fortunately the bots usually find them. Thank you for catching that, which obviously slipped through!  Walkerma 07:55, 8 November 2006 (UTC)

message: Hi. I don't know how I ended up here, but the only thing I was interested in finding out isn't mentioned on the page. Could someone add a short paragraph explaining what the three IIIs in iron(III) oxide mean for those initiates such as I?  Thanks. Dennywuh 01:00, 12 December 2006 (UTC)
replies: text: It is a Roman numeral 3, and it indicates that the oxidation state of the iron here is +3.  If you write it as an ionic structure, that means the iron has a charge of +3.  There is another iron oxide where the iron has a +2 oxidation state, and that is called iron(II) oxide. Walkerma 02:55, 23 March 2007 (UTC)

message: Is there really a need for citation at the end of this paragraph from the article?
This process is used to weld thick metals such as rails of train tracks by using a ceramic container to funnel the molten iron in between two sections of rail. Thermite is also used in weapons and making small-scale cast-iron sculptures and tools.[citation needed]
I assume the doubted claim is the one about thermite being used to make sculptures and tools.   I have used thermite to cast jewelry - I used the commercially available cadwelding material to produce a pair of copper alloy rings for my wife and I. I even took pictures if there's any doubters. The rings were nice enough but not really what the wife wanted and the copper turned my skin green. the point is though that metal casting can be and is done with thermite.

message: Hi, I found out from the technical sales guy at Dessicare that the oxygen busters that they use in food products have iron in them which oxidises over time and then becomes Iron Oxide II and Iron Oxide III - I would like to know if this can be added to soil in my garden (and everyone's gardens) and if it is fine to do so. The main purpose is to promote some reuse of the oxygen busters (but cutting them open to get the iron out) as the are so prolific now and I hate that they cannot be recycled at all. Any help appreciated.

message: The article claims that hematite doesn't melt, it decomposes at 1566 degrees C. Decomposes to what? Further, other websites give a melting point for hematite of around 1566 degrees:
http://www.reade.com/Products/Oxides/hematite.html, http://eprints.ru.ac.za/252/3/PUBLICATIONS/JTAC65.pdf, http://www.reade.com/home/704, http://www.espimetals.com/index.php/msds/150-iron-oxide-red-fe2o3, http://www.pestell.com/msds/Red%20Iron%20Oxide.pdf. The 2011-2012 Rubber Handbook gives a melting point of 1539 deg. C.  In line with the first reference I've listed, I suspect that someone confused melting point and boiling point information.
However, I'm not certain of this.  While I'm going to change the article, I hope someone with more chemical knowledge will check into this.Saintonge235 (talk) 08:17, 11 December 2012 (UTC)
replies: text: Restored as your edit made it invisible - the infobox syntax is touchy that way. As to the specific temp, don't know. I would be dubious of the boiling point w/out specifics, and likely decomposes well below a bp depending on containing atmosphere ... Vsmith (talk) 11:39, 11 December 2012 (UTC)

message: The Chemspider identifier is flagged in the infobox, however the number seems to be correct - see http://www.chemspider.com/Chemical-Structure.14147.html
Perhaps this has already been corrected but the flag has not changed.  Is the flag supposed change automatically?  If the flagged item is corrected without removing or changing the flag it will waste the time of other editors.  The "verify" link at the bottom of the infobox goes to this page: http://en.wikipedia.org/w/index.php?title=Special:ComparePages&rev1=464185021&page2=Iron%28III%29+oxide, however it's not clear to an uninitiated editor how to indicate on this page that the Chemspider identifier seems OK and the flag should be changed or removed.
Really, this flag business seems like inside baseball.  If the flags are not publicly changeable, why make the flag links and instructions publicly visible?  Isn't this against the spirit of a publicly editable encyclopedia?  Ggpauly (talk) 02:26, 7 June 2013 (UTC)
