Rusting is a chemical reaction, which refers to a reaction that occurs when one substance turns into something else. Iron starts out as a shiny metal, but if it comes into contact with damp air, it begins to rust. As iron, oxygen and water react, the iron turns from a shiny gray to a dull orange, which makes it easy to determine if rusting has occurred.
The final product of this reaction is ferric oxide, also called iron oxide, which has two atoms of iron for every three atoms of oxygen.Learn more about Solutions & Mixtures
There are several products that remove rust from metal by using either phosphoric or hydrochloric acid to dissolve it. These solutions typically involve soaking time for maximum effectiveness. There are also nontoxic solutions that use an acid-free process to take away rust, relying on chelation to remove the iron.Full Answer >

Decomposition is a type of chemical reaction in which one or more compounds are broken down into simpler compounds or elements. This is the opposite of a synthesis reaction, in which two or more elements or simple compounds combine to create one or more slightly more complex compounds.Full Answer >
Iodine crystals are not a homogeneous mixture, as they cannot be physically broken down into pure compounds or elements. Because the only element present in this case is iodine, which crystallizes in the solid phase, iodine crystals can be classified as a pure substance.Full Answer >
