The rust formula is approximately Fe2O3 x H2O however, the exact amount of water in the formula is variable. However, there is no physical process to obtain the iron from the rust. What is the Chemical Formula of Rust?The chemical formula of a compound is defined as the symbolic r...

Where a compound only contains nonmetal atoms, a covalent bond is formed by atoms sharing two or more electrons. Nonmetals have four or more electrons in their outer shells (except boron). With these many electrons in the outer shell, it would require more energy to remove the electrons than...
During a physical change the substance, element, or compound does not change. However, the change might involve changes in energy. For example, ice melting is a physical change in that an increase in thermal energy changes the state of matter of water. However, the water molecules themselves ...
it gets covered with a red-brown flaky substance called rust. This is called rusting of iron. During the rusting of iron, iron metal combines with the oxygen (of air) in the presence of water (moisture) to form a compound ‘iron oxide’. This iron oxide is rust. The process of rustin...
In chemistry, a reaction happens when two or more atoms on molecules interact and transform into a different compound. For example, rusting occurs when an 'oxidation' reaction makes iron combine with oxygen to form rust-coloured iron oxide. The opposite process, such as reactions that remove oxy...

Rust is nothing but Iron Oxide, a compound formed when iron reacts with oxygen and water. Although it’s a complex process, its chemical equation can be written as: 4Fe + 3O2+ 6H2O → 4Fe(OH)3 This process is also a good example of corrosion, where metal surfaces are degraded into...
