moisture contains water which is essential for rusting to occur.
Rusting can't occur unless oxygen and water are available .
4Fe + 6(O2) + X(H2o) --->2( Fe2O3).X H2o
X depends on the amount of water present ..
hope this helps

Why does paint affect the formation of rust?
Bare steel + moisture + oxygen = rust. Paint provides a barrier to shield the steel from moisture and oxygen.
Why do handles start to rust when the paint is scratched?
Handles start to rust when the paint is scratched because the protective layer of paint is compromised, exposing the metal underneath to moisture and oxygen. Moisture and oxygen react with the metal, leading to the formation of rust. Rust is a corrosion product that weakens the metal and causes the rusted area to expand over time.
Can sodium produce rust?
No. It only decreases rust formation.
Does kill rust primer actually kill the rust?
Kill rust, or direct-to-rust primer and paints, do not actually "kill" the rust, they encapsulate the rust, preventing oxygen and moisture from contacting and spreading the rust. Unlike other paints, they are impervious to moisture and that helps to considerably slow the growth of rust.
What weather conditions does not cause rust?
Dry weather, like the desert. Moisture causes rust.
Is rust a type of fungus?
No, rust is the formation of a layer of a metal oxide on the surface of a metal.
What is in the air that cause needle to rust?
oxygen and moisture
What do the formation of rust in the formation of cottage cheese have in common?
Both involve chemical reactions

What iron article rust became of the formation of?
because when gandu and rust get together they form sulphur
What is an antirust?
An antirust is a substance which prevents the formation of rust.
Where will iron rust more quickly-in the tropics or antarctica and why?
Tropics as iron rusts due to the the moisture present in the air.In Antarctica there is no or very little moisture whereas in the tropics the amount moisture is high. ===================== The formation of rust requires not only iron, but also oxygen and water. The most common form of rust is FeO(OH), which, when it occurs naturally, is called goethite. 4Fe(s) + 3O2(g) + 2H2O(l) --> 4FeO(OH)(s) Rust which forms under water is Fe(OH)3. The dehydrated rust found in arid regions is Fe2O3. Despite the abundance of oxygen in the interior of Antarctica, little rusting occurs because of the lack of water. The interior of Antarctica is a very, very dry place.
