There is anhydrous iron oxide- think of a black fireplace poker, or a gun barrel. That black iron oxide is magnetite, it is a fairly good protective coating against corrosion. Rust incorporates water into the crystal structure, which makes rust expand like popcorn, and flake away, exposing fresh metal to air and water. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp lollersauce914 Added an answer on August 13, 2019 at 12:26 pm Rust is a compound of Oxygen and Iron in the presence of water. The reaction between Iron and Oxygen that forms rust is spontaneous, that is it requires no outside energy under standard conditions. Oxygen tends to react with lots of things very easily. Iron is just one of them. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp mb34i Added an answer on August 13, 2019 at 12:39 pm Rust is iron oxide. Most metals that are exposed to oxygen in the air will react with it and “rust” in some way, though it’s not called rust unless the metal is iron specifically. Some metals, like aluminium and copper, the oxide (rust) covers and insulates the rest of the metal from air, so it forms like a protective layer. But iron rust is porous, and absorbs moisture and oxygen, so more and more of the iron rusts. Examples of other oxides: carbon dioxide, silicon oxides (rocks, sand), aluminium oxide (sapphire, ruby), nitrous oxide. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
