What similarities iron have a similar reaction with water as potassium?

Potassium react violent with water, iron react only if oxygen is present.


Does chocolate milk make iron rust?

It is possible only in the presence of oxygen.


Can water vapor rust iron?

Rusting will only occur in the presence of both water and oxygen. In the presence of oxygen, water vapour in the air will cause rusting to occur. So unless you are talking about the iron coming into contact with water vapour but when there is no oxygen, the answer is yes.


Will nails rust in water?

Nails do not rust in water. Nails only rust in water if oxygen is present. This is because the iron in nails react with oxygen and water to form a compound called hydrated iron(III) oxide.


Why is rusting of iron fast in rainy season?

Iron rusts because it reacts with oxygen. The oxygen in water reacts with iron quicker than oxygen in air, and the air outside is often damp, and there is the rain as well.


Does rusting of iron require the presence of oxygen and water for it to occur?

No. Only oxygen must be present. The process of rusting is the reaction of iron metal (Fe) combining with oxygen gas (O2) to form iron oxide (FeO or Fe2O3). Water (and salt) speed up this reaction a great deal, but oxygen is the only one that is necessary.


Does iron react with cold water?

The iron is rusting because of its chemical bonding with oxygen, which creates ironoxide.


How painting of iron tanks prevent it from rusting?

Iron can be prevented from rust not only by painting but also by coating the iron byzinc . But when we paint iron ,the hydrated oxide presented in the rust iron(Fe2O3.2H2O)can be prevented . Reaction of the iron with air ,water Etc can be prevented.


Why does gold not rust?

Rust is the common name of the corrosion products of Iron. These are the results of the reaction of iron with water and oxygen. Rust is also the term used only for iron oxides (Iron which reacts with oxygen). For corrosion of gold, see related link below. == ==


Is rust the only reaction between iron and oxygen?

No, sometimes water is involved, which is another thing that can create rust.


What is rust and how does it form?

Rust forms when metals containing iron mix with the oxygen in the air or the water and create a compound named iron oxide. This compoumd has water molecules, so we call it a hydrated compound. Chemically and very simply speaking, iron atoms lose a few electrons to oxygen atoms. This process, where electrons are lost from atoms, is the oxidation process. When oxidation occurs it produces a chemical reaction that creates iron oxide


What rusts in water?

"Rust" is a specific form of corrosion - where iron joins with oxygen. Therefore, the only thing that "rusts" in water is metal containing large amounts of iron, either "iron" or "steel." A lot of things will corrode, dissolve or otherwise deform if you put them in water.
