Iron Oxide and Rust are the same thing right? Can it come from any metal, or does it have to be Iron!?
Iron oxide inhabits rust. They're not the exact same thing. I guess it can come from any metal and it doesn't exactly have to come from iron.
Well, I am a chemist. Iron oxide can be formed from any metal that contains Iron. All you need is water and in a cars case, the weather to react with Iron to form Iron Oxide. And yes, Iron oxide and rust are the same thing. A lot of things in chemistry will hold different names. But, Iron oxide can not come just any metal, the product needs to contain Iron. Magnesium and Sodium are just a few metals on the periodic table, they react differently, add water to Sodium and it will catch fire and explode if you have enough and Magnesium reacts with a flame (be careful it is VERY bright) to form Magnesium Oxide. Hope this helps. Wee-Man.
Rust is the common name for Iron (III) oxide, Fe2O3. There are several other oxides of iron that form naturally, including some hydrated forms. Rouge and the mineral hematite are other forms of Iron (III) oxide. Iron (II) oxide is a black powder with the formula FeO. Magnetite or loadstone is called Iron (II,III) oxide. It has the formula Fe3O4. All forms of Iron oxide come from the oxidation of metallic Iron. Other metals give similar oxides, but with different formulas and properties.
