What else can I help you with?
Is a solid and forms rust when reacted with air.?
Iron
What element is a solid and forms rust when reacted with air?
Rust is most of all 'metal oxide' which is chemically formed by reaction of certain metals (not all) with oxygen (gas, 20% in air)
Which element is a solid and forms rust when reacted with air?
The element is iron.Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture.
What is found in the air that reacted with the metal making it dirty?
It is not dirty - moisture reacts with the metal and forms iron oxide, or rust.
What forms when an alkaline earth metal oxidizes in the air?
Rust
Is rust compound?
Yes Rust is a compound because of iron +air
Is a fridge door going rusty a chemical or physical change?
The formation of rust is a chemical change because the steel (iron) in the door has reacted with oxygen in the air to form a new substance called rust, which has properties different from the iron and the oxygen that reacted.
What gas you needed to make iron rust?
Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
Is rust a physical are chemical?
Rust as seen on the surface of iron/steel is a physical entity ; a solid. . It is iron oxide. It has become rust by a chemical reaction. Iron has reacted with oxygen(air) (& Water is present ) to form rust . 2Fe (s) + 3O2 = Fe2O3(s) Iron has several oxides viz. FeO, Fe2O3, Fe3O4 FeO ( Iron(II) Oxide/ Ferrous Oxide) is a solid , green in colour and readily oxides to Fe2O3 . Fe2O3 ( Iron(III) Oxide/ Ferric Oxide) is a solid, red/brown in colour and stable( does not readily reduce in the air). Fe3O4 (Magnetite) is a dark coloured solid, stable at room temperatures , and was the 'lodestone' of viking navigators. As the name suggests it responds to magnetic fields.
Rust Fe2O3 forms on an iron Fe pipe after prolonged exposure to humid air What type of change does this illustrate?
Rust forms on an iron pipe after prolonged exposure to humid air. What type of change does this illustrate
What is a reddish flaky coating that forms when objects containing iron corrode?
The reddish flaky coating that forms when objects containing iron corrode is called rust. Rust is a result of the oxidation of iron when exposed to moisture and oxygen in the air.
What is the rusting of silver?
The rusting of silver is not technically "rusting," as rust is specific to iron. Silver does not rust, but it can tarnish when exposed to air and sulfur compounds, forming a dark layer on the surface. This tarnish can be removed by polishing the silver.
