O2 is necessary for the rusting because the iron forms an iron oxide complex with the oxygen.
Fe (s) + O2 (g) --> Fe2O3 (s)
Rusting typically requires the presence of oxygen in the gas phase, as this initiates the oxidation reaction that leads to the formation of rust. Additionally, moisture or water is also needed for the process of rusting to occur, as it helps accelerate the oxidation of the metal.
Rusting of iron: Fe + O2 + H2O → Fe2O3•nH2O Formation of copper(II) oxide: 4Cu + O2 → 2Cu2O Corrosion of aluminum: 4Al + 3O2 → 2Al2O3 Corrosion of silver: 4Ag + O2 + 2H2S → 2Ag2S + 2H2O
Nails do not rust in milk because milk does not contain the elements necessary for the rusting process to occur. Rusting requires moisture, oxygen, and iron to create iron oxide, which is what we commonly refer to as rust. Milk lacks the oxygen component necessary for rusting to happen.
Differences:RUSTING :Rusting is a slow process.Little heat is released.Both air and moisture are necessary for rusting.COMBUSTION:Burning is fast oxidation.large amounts of heat are released.Only air is necessary for combustion.In other words, Rusting is much slower than combustion, and rusting in the strictest sense can occur only with iron or its alloys.
The balanced chemical equation for the reaction FeS2 + 7/2 O2 → Fe2O3 + 4 SO2 is: 4 FeS2 + 11 O2 → 2 Fe2O3 + 8 SO2.
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
2Cu+H2O+CO2+O2=Cu(OH)2.CuCo3
fe + O2 = feO
To stop them rusting.
If they are Iron Nails it is:FeH + O2 --> CO2 + H2OThis is Unbalanced
No. Rusting is a chemical change because the chemical composition is changed from iron to iron oxide. The iron reacts with oxygen in the atmosphere, forming iron oxide. Fe + O2 --> Fe2O3
Oxygen is responsible for rusting and combustion. Chemical formula for it is O2.
A chemical change, redox reaction: 2Fe(s) + O2(g) --> 2FeO(s)

Rusting iron (or steel) is a chemical reaction. It is where iron reacts with water and oxygen to form iron(III) oxide. Fe + H2O + O2 -> Fe2O3.H2O Note that the equation above isn't balanced.
