Is rust compound?
Yes Rust is a compound because of iron +air
What happen when iron is exposed to air?
If an iron nail is exposed to air for a long time it reacts with the water vapour (moisture) and oxygen present in the atmosphere and a reddish-brown powdery coating is formed on it known as RUST (Fe2O3.xH2O) .
What 2 things are needed to make iron rust?
Whenever water or air is around iron for a while it can rust because the iron bonds to the oxygen forming iron oxide.
Why doesn't rust protect iron?
Rust is porous, it allows air & water to get to the metal underneath.
Is the rust of an iron nail a compound?
Iron (Not rusted) is an element. However, when iron is in contact with air and water, rust will form on its surface. Rust is an oxide of iron and rust is a compound. Since rust is red/brown in colour it means that the iron has been oxidised to oxidation state '3'. , by the action of water and air. The chemical symbol form iron is Fe (Ferrum - Latin) The chemical formula for rust is Fe2O3 (Ferric oxide). There are other oxides of iron . They are FeO (ferrous oxide = green in colour) and Fe3O4 ( magnetite - grey/black in colour)
What element does iron react with in damp air?
Iron reacts with oxygen in air to for rust.
Is rust compound?
Yes Rust is a compound because of iron +air
What is formed when iron combines with oxygen in the air?
Iron reacting with oxygen produces rust, Fe2O3 (Iron (III) oxide) or FeO2 (Iron (II) oxide) depending on the composition of the iron.
How much oxygen is consumed in forming iron rust?
Technically, all of the oxygen in the air is consumed when forming iron rust. Air is approximately 20 percent oxygen, and that entire amount is consumed when forming iron rust.
What happens when air is combined with substances like iron and water?
Air, iron and water will cause the iron to rust.
Is Iron a nonreactive metal?
NO! It reacts with air to form iron oxide (AKA rust) and water to form iron hydroxide (AKA rust)
Why do Metal rust?
Rust is the name given to the compound Iron oxide, which forms when Iron reacts with Oxygen in the air. Metals which do not contain Iron or Chlorine don't rust.
What 2 elements make up rust?
Iron and oxygen
What happen when iron is exposed to air?
If an iron nail is exposed to air for a long time it reacts with the water vapour (moisture) and oxygen present in the atmosphere and a reddish-brown powdery coating is formed on it known as RUST (Fe2O3.xH2O) .
What does iron form in damp air?
I think it's rust (iron oxide or hydrated iron oxide) because when iron reacts with water and air, rust is the product. At least that's what we were taught in science today!
Is solid and forms rust when reacted with air?
Iron
Is a solid and forms rust when reacted with air.?
Iron
