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)

Is rust compound?
Yes Rust is a compound because of iron +air
When a nail rust iron from the nail combines with oxygen from the air to form what?
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
Is letting a nail rust a physical or chemical change?
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
What is the new product of a rusting nail?
When the iron in a nail combines with oxygen it forms iron oxide. We call this rust.
Why is rust an element?
Rust is not an element. Rust is a compound which is made up of iron oxide.
Is an iron nail a element compound or mixture?
in its pure form, iron is an element, but that may not be what you are referring to.... if you have iron oxide (rust), this is a compound of iron and oxygen.
Is an iron nail rust a physical change?
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
Is a rust forming on an iron nail chemical or physical?
A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.
What type of change rusting of nail?
It's an oxidation reaction forming iron oxide (rust). Basically: iron + oxygen = iron oxide Iron, (Fe) is an element and react easily with the element Oxygen (O2) the resultant material is a compound known as rust or iron oxide, (FeO2) this proces is known as oxidization.
Why does an iron nail rust?
Iron present in the nail oxidizes in oxygen to form the iron oxides
What happens to nail after heating?
It either cleans the nail, or makes the nail have rust.
Will 7up rust a nail?
Well I did and experiment for 30 days with 7up and an iron nail and it did not rust.
Is rust compound?
Yes Rust is a compound because of iron +air
Explain why the mass of a rusted nail would be greater than the mass of the nail before it rusted Assume that all the rust is still attatched to the nail?
Rust is a compound of iron and oxygen. Therefore the mass is greater because oxygen has been added.
When a nail rust iron from the nail combines with oxygen from the air to form what?
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
Why Rust is compound?
A compound is 2 or more elements permanently combined. Rust is a combination of iron and oxygen, both elements- into iron oxide, a compound.
Is rust iron oxide a compound?
Rust is made by Fe and O. So rust is not organic.
