Iron
Added:
Many (not all) metals are rusting because they can donate electrons to oxygen (or another oxidiser, like strong acid)
Example:
2Fe --> 2Fe2+ + 4 e-
O2 + 4 e- --> 2 O2-
________________________ +
2Fe + O2 --> 2 FeO
Rust is formed when oxygen combines with metal that is untreated with items that keep the metal looking young and new.
Iron is the only metal that can rust. The usual term for the destruction of a metal by oxidation is corrosion, and 'rust' or 'rusting' is the term for corrosion specific to iron and its compounds.
Metal turns into rust when exposed to oxygen and moisture over time, a process known as oxidation. The oxygen in the air reacts with the metal's atoms to form a new compound, which appears as reddish-brown iron oxide, or rust. This process can be sped up by increasing the metal's exposure to water and oxygen.
Citric acid can react with metal surfaces, specifically with metals like aluminum and iron, to form metal salts and hydrogen gas. This reaction can result in corrosion and deterioration of the metal surface over time.
Iron corrodes to form an iron oxide. This oxide is commonly called rust. The reaction involves a transfer of electrons from iron to oxygen. Water is commonly slightly acidic due to the carbon dioxide in the atmosphere. The acid brings hydrogen ions in contact with the iron which allows the formation of an iron hydroxide intermediary compound which hastens the formation of iron oxide, rust. Ships at the bottom of the ocean rust more slowly as there is less oxygen and the water is less acidic. The only way to prevent rust forming is to prevent oxygen coming in contact with the iron through the application of paint, oil, plastic or another metal.
acid rain is what most commonly makes metal rust
it makes it rust and corrode
Cans rust when the metal coating on the surface of the can is damaged, allowing oxygen and moisture to come into contact with the metal. This leads to a chemical reaction where the metal (typically steel) oxidizes, forming iron oxide, which is commonly known as rust.
Because it takes shiney metal and makes it rusty
Any water makes iron rust. Rust is iron oxide. It happens when water allows the oxygen to dissolve in it and get to the surface of the metal. Salt water has dissolve salts in it which makes it work faster.
A 25 cent coin (quarter will not rust- they are no made of ferrous metal. They may tarnish- usually from exposure to air and sulfur.

The best rust solution for metal is a rust converter or rust inhibitor that can stop the rusting process and protect the metal from further corrosion.
Rust is a form of corrosion that weakens metal by breaking down its structure. It can lead to the degradation of metal over time, making it less strong and more brittle. Regular maintenance and protective coatings can help prevent rust and preserve the strength of metal.
No, rust is the formation of a layer of a metal oxide on the surface of a metal.
the acidity and chemicals in coke are strong enough to reverse the displacement reaction
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
