what are chemical properties of rust?
237968
Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3). Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust.

Rust, iron (III) oxide, forms when iron and oxygen react. The balanced chemical equation for this process is: From the balanced chemical equation 4 iron atoms react with 3 oxygen molecules to yield 2 iron (III) oxide formula units.

Ability to oxidize - This is what takes place by gaining oxygen, losing hydrogen, or losing electrons, and is a chemical property that results in the oxidation number of a substance being changed. An example of this is rust.

In this work, some physical – chemical properties are determined and some comparations of characteristics were performed in both wheat and flour. Characteristics that were observed in this work are moisture content, ash content, protein content, Zeleny sedimentation value, gluten content and water adsorption values.

Chemical weathering changes the mineral composition of rocks. If you have seen an old rusty nail, you have witnessed the result of a chemical reaction and a chemical change. The steel in the nail contains iron. Oxygen in air and water react with the iron to form rust.

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

Oxpho-blue is a phosphate process, so it is very durable and rust resistant. Oxpho-blue is a phosphate process, so it is very durable and rust resistant.

In summary, stainless steel does not rust because it is sufficiently reactive to protect itself from further attack by forming a passive corrosion product layer. (Other important metals such as titanium and aluminum also rely on passive film formation for their corrosion resistance.)

The presence of water and oxygen is essential for the rusting of iron. Impurities in the iron, the presence of water vapor, acids, salts, and carbon dioxide hasten to rust. Pure iron does not rust in dry and carbon dioxide free air.

Iron oxides are chemical compounds composed of iron and oxygen. There are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron(III) oxide. ... Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes.

Oxidation is described as an electrochemical reaction between Oxygen and other substances, whether metal or living tissues. It can also be described as a loss of electrons or Hydrogen atoms, which results in a gain of Oxygen atoms. Rust is often the result of oxidation when it occurs on metals or metallic materials.
