O2 is necessary for the rusting because the iron forms an iron oxide complex with the oxygen.

Which type of gas does rusting require?
The gas that is required to allow rusting to occur is Oxygen
Is there any difference between rusting and combustion since both involve oxidation?
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.
What accelerates the rusting process?

List 2 necessary conditions for rusting of iron rod?
Oxygen present Water Present Therefore leaving a metal unprotected will inevitably result in the rusting of it
What the answer for FeS2 plus O2 - and get Fe2O3 plus SO2?
That is an oxidation reaction (I am translating the numbers into subscripts) which in this case is also called rusting.
What are the conditions necessary for rusting?
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
Which type of gas does rusting require?
The gas that is required to allow rusting to occur is Oxygen
What is the chemical reaction for rusting copper?
2Cu+H2O+CO2+O2=Cu(OH)2.CuCo3
What chemical equations are used to describe the process of rusting?
fe + O2 = feO
Why is it necessary to paint iron gates?
To stop them rusting.
What is the general equation for rusting nails combustion reaction?
If they are Iron Nails it is:FeH + O2 --> CO2 + H2OThis is Unbalanced

Rusting iron physical change?
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
What kind of change happen to a rusting of iron?
A chemical change, redox reaction: 2Fe(s) + O2(g) --> 2FeO(s)
What is a very reactive element responsible for rust and combustion?
Oxygen is responsible for rusting and combustion. Chemical formula for it is O2.
Is Iron rusting Chemical changes?
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.
