What is rust composed of?
Rust (in its "regular" red form) is an iron oxide called iron(III) oxide. It's formula is Fe2O3, and we call it ferric oxide or hematite. And that's different from iron (II) oxide FeO, or iron (II,III) oxide Fe3O4. There are three basic forms of oxidized iron, and there they are. Wikipedia has more information, and a link to their post is provided below. Rust is basically ferric oxide caused by the action of air, or to be more precise, the action of oxygen and water droplets on iron.
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 is iron refined from?
In short, the iron ore hematite (Fe2O3). Iron is a raw material and you technically don't need to refine anything to get it. But because iron oxidizes (rusts) in the presence of oxygen, the iron ore must be heated and melted to remove the oxygen. During the process, the iron is usually mixed with carbon to increase it's strength. The end result is steel.
Clouds owe their existence to the presence of atmospheric?
Clouds are made out of atmospheric water vapor. They form in part due to cooling in the upper atmosphere.
Does metal rust in cold heat or water?
Yes. Whether the water is fresh or salty, it still has oxygen in it and the metal will oxidize over time. If the metal is Gold, plutonium or titanium it wont rust because these metals dont oxidize. If you place metal (iron) in oil, it wont rust.
Is iron oxidised or reduced when it corrodes?
Iron has been oxidised (by an oxidant) due to its loss of 2 or 3 electrons:Fe --> Fe2+ + 2e- , or Fe --> Fe3+ + 3e-The oxidant picked them up.(Examples of oxidants:2H+ + 2e- --> H24 H2O + O2 + 4e- --> 4 OH-
Was does iron react with?
Iron can react with water in the presence of air and form rust.
What is the most common magnetic element that corrodes to form rust?
The most common magnetic element that corrodes to form rust is iron. When aligned, atoms of iron will possess a magnetic field that will lead to interaction with other magnetic, ferrous materials. Iron will oxidize to form rust.
What metal corrodes easily to form rusty oxide?
This metal is iron.
Why does the mass change if iron corrodes i.e 5.04g before and after 5.16g?
The additional mass is the amount of oxygen that has combined with iron to form iron oxide.
When iron oxide is made does the iron take the oxygen out of the water or out of the air?
Iron oxide is typically formed by the reaction of iron with oxygen in the air, not water. Iron reacts with oxygen in the presence of air to form iron oxide. Water does not play a significant role in the formation of iron oxide in this context.
What kind of chemical causes rusting of iron?
The chemical that causes rusting of iron is oxygen in the presence of water. This process is known as oxidation, where iron reacts with oxygen to form iron oxide (rust) in the presence of moisture.
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.
How rusting of iron needs both moisture and oxygen?
Rusting of iron is a chemical reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust). The presence of moisture is necessary to allow the iron to dissolve and come into contact with oxygen from the air, initiating the rusting process. Without oxygen, the iron cannot oxidize to form rust.
What is the compound needed to make iron rust?
Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
What is a common example of an oxidation reaction?
Rusting of iron is a common example of an oxidation reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust).
What happens to iron and sulphur when you add water?
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
