Humidity ... damp air, water from rains.
Because
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
When the iron in a nail combines with oxygen it forms iron oxide. We call this rust.
A nail made out of just iron will rust really fast if it is exposed to oxygen. Nails available now, are galvanized nail which has a coating of copper metal on the surface of iron nail. This slows down process of rusting. Exposing a iron nail to water and other acidic environment along with oxygen, can make a nail rust pretty fast.
No - the drying agent prevents the corrosion (rusting) of iron because the agent absorbs all the moisture and none if it will react with the iron nail thus no rust is made.
teehee
Iron present in the nail oxidizes in oxygen to form the iron oxides
It either cleans the nail, or makes the nail have rust.
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Well I did and experiment for 30 days with 7up and an iron nail and it did not rust.

it can rust it reacts with atmosphere and reacts with iron oxide then it get rusted

This really depends on the concentration of impurities in water. More the impurities, faster it will rust the iron nail. To reduce rusting of any iron the best way is to paint the nail.
It's not just saltwater that makes a nail rust, even water makes a nail rust. Rust is simply oxidation, it happens when oxygen comes into contact with something and creates a chemical reaction and creates "oxides". Iron + oxygen = Iron oxide (red rust on steel)
