water/oxygen and iron
Many, including Iron Sulphate, Sulphide, Oxide (rust) and more
Iron compounds do not rust. Iron and its alloys can rust. Although other metals can corrode it is usually only called rust when it is iron that is corroding.
Water, quartz, rust, and sugar are all common, important compounds containing oxygen.
Oxides. Like Iron Oxide (rust).
No, helium does not rust or tarnish because it is an inert gas. Inert gases like helium do not readily react with other elements or compounds to form rust or tarnish.
A fallen [dead] tree does not rust. Rust is a term specifically applying to the oxidation of Iron and some compounds of Iron. The breakdown [biodecompositon] of trees and other plant materials is accomplished by the action of living microbial "critters" that eat and digest the plant materials resulting in different compounds.
carbon dioxide Iron and Oxide form rust
Tarnish is to silver as rust is to iron. Tarnish is a layer of corrosion that forms on silver when it reacts with sulfur-containing compounds, while rust is the result of iron reacting with oxygen and moisture.
Rust occurs when a metal oxidizes. The ingredients needed to make a metal rust is oxygen and breaking compounds such as the citric acid in orange juice or salty water in oceans.
Rust is a chemical compound, essentially an iron oxide.
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.
No. Nitrogen is a nonmetal, which is a gas at standard temperature. Only metals rust or corrode.
