What is rust?

Answer 1

­R­ust is the common name for a very common compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen, so readily, in fact, that pure iron is only rarely found in nature.

Iron (or steel) rusting is an example of corrosion, an electrochemical process involving an anode (a piece of metal that readily gives up electrons), an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons). When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode. As oxygen combines with the metal, electrons are liberated. When they flow through the electrolyte to the cathode, the metal of the anode is removed by the electrical flow or converted into metal cations in a form such as rust.

Answer 2

Rust is a systems programming language developed by Mozilla that focuses on safety, speed, and concurrency. It provides memory safety guarantees without needing a garbage collector, making it suitable for writing reliable and efficient software. Rust's syntax is similar to C++ but with modern features like pattern matching and traits.

Answer 3

the slow reaction of an iron piece reacting with moisture

When Something stays in water and rust.

Rusting occurs when iron reacts with the oxygen in the air.
