What else can I help you with?
Can you reverse an iron nail rusting?
No, once an iron nail begins to rust, it cannot be reversed. Rust is a chemical reaction between iron, oxygen, and water, forming iron oxide. This process cannot be undone.
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.
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 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.
Why does a rusty nail weigh more than the original nail?
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Is rust forming on an iron nail is that a mixture?
Rust forming on an iron nail is a chemical reaction rather than a mixture. Rust is a compound made up of iron oxide that results from the reaction of iron with oxygen and water in the presence of air.
Can you reverse an iron nail rusting?
No, once an iron nail begins to rust, it cannot be reversed. Rust is a chemical reaction between iron, oxygen, and water, forming iron oxide. This process cannot be undone.
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 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.
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)
Why does a rusty nail weigh more than the original nail?

When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
