What else can I help you with?
Is a rusty iron nail a homogeneous mixture?
No, a rusty iron nail is not a homogeneous mixture. It is a chemical compound made up of iron and oxygen that has undergone oxidation, causing it to form rust.
What type of gas makes a wet iron nail rust?
The gas that makes a wet iron nail rust is oxygen. When iron comes into contact with oxygen in the presence of water, it undergoes a chemical reaction called oxidation, forming iron oxide, which is the rust that we see.
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.
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)
Is rust forming on an iron nail a chemical change?
Yes, rust forming on an iron nail is a chemical change. It involves the oxidation of iron in the presence of oxygen and water to form iron oxide (rust), which has different chemical properties than the original iron.
Why is rust forming on a nail not a pysical change?
It is not a physical change because rust is no longer iron, but is iron oxide, a completely different substance.
What is an iron nail reactive with when forming rust?
An iron nail is reactive with oxygen and water when forming rust. This reaction occurs when iron is exposed to moisture and oxygen in the air, leading to the formation of iron oxide, which we commonly know as rust.
Is a rusty iron nail a homogeneous mixture?
No, a rusty iron nail is not a homogeneous mixture. It is a chemical compound made up of iron and oxygen that has undergone oxidation, causing it to form rust.
What type of gas makes a wet iron nail rust?
The gas that makes a wet iron nail rust is oxygen. When iron comes into contact with oxygen in the presence of water, it undergoes a chemical reaction called oxidation, forming iron oxide, which is the rust that we see.
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.
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.
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 does an iron nail rust?
Iron present in the nail oxidizes in oxygen to form the iron oxides
What happens to an iron nail when it rust?
When an iron nail rusts, it undergoes a chemical reaction with oxygen and water in the air, forming iron oxide (rust) on its surface. This process weakens the iron nail and can lead to degradation over time.
What happens to nail after heating?
It either cleans the nail, or makes the nail have rust.
What cause a nail to rust in water?
The oxygen in the water reacts with the metal in the nail - forming metal oxide (rust)
