What is the formula of rust?
The chemical formula of rust is iron(III) oxide, which is represented as Fe2O3. It forms when iron reacts with oxygen in the presence of water or moisture.
Is rust an element compound or mixture?
Actually, Rust is a mixture, of two compounds = Hydrated Iron(III) oxide [Fe2O3.nH2O] and Hydrated Iron(III) oxide-hydroxide [FeO(OH).nH2O] . Both the compounds are red giving colour to Rust.
Chemical equation for rust?
2Fe(s) + 2H2O(l) + O2(g) ==> 2Fe2+(aq) + 4OH-(aq) This is the equation for rust. ---- NOT EXACTLY Rust is a solid, it doesn't exist as ions in solution. Also, in rust, iron is in the +3 oxidation state. There are three common forms of rust. Rust formed under water is Fe(OH)3. Rust formed in humid air is FeO(OH). Only when rust has completely dehydrated will you see it as Fe2O3. The reaction for the rust that we see around us most often is: 4Fe(s) + 3O2(g) + 2H2O(l) --> 4FeO(OH)(s) FeO(OH) is also formed naturally, and is the mineral called goethite.
Does iron oxide cause rust?
Yes, iron oxide is the chemical compound that forms when iron reacts with oxygen in the presence of moisture, leading to rust. Rust is a common form of corrosion that weakens and deteriorates iron and steel.
What is the name of an element which will rust?
Iron is an element that will rust when exposed to oxygen and moisture in the air.
