CaCl is extremely hygroscopic (water-attracting), so it will take up any moisture and keep the iron nail dry.
Two conditions for rusting are oxygen and water.
No, nail does not rust in anhydrous calcium chloride because rusting requires the presence of water to occur. Anhydrous calcium chloride is a desiccant that absorbs moisture from the surrounding environment, preventing the nail from coming into contact with water and thus inhibiting rust formation.
The iron would not rust, because calcium chloride is a desiccant. For rusting to occur there are two vital components: water and oxygen. Since calcium chloride is a desiccant, it would absorb the water, so rusting would not occur.
The nail is iron. Rust is a chemical reaction. 4Fe + 3O2 --> 2Fe2O3 When the nail rusts it becomes chemically bonded to oxygen. This combination is heavier than just iron. Therefore, it gains mass.
Rust forms on a nail in hydrogen peroxide because hydrogen peroxide can act as an oxidizing agent, providing oxygen to the iron in the nail, which leads to the formation of iron oxide (rust) through a chemical reaction. Additionally, the presence of water in hydrogen peroxide allows for the corrosion process to occur more rapidly.
No, that wouldn't be decomposition since it's not breaking down. It's actually an example of oxidation. If a nail is iron or Fe(s) then a rusty nail would be Fe2O3 (Iron Oxide). I believe the balanced formula would look like this... 4Fe(s) + 3O2 --> 2Fe2O3 If anybody sees any flaws in my logic, please feel free to correct. :)

Yes, it is possible; supplemetary the chloride ion is corrosive.
No, metal does not rust when placed in calcium chloride. This is because calcium chloride is a desiccant that absorbs moisture from the environment, preventing the formation of rust on the metal surface.
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
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.
Rust forming on an iron nail is a chemical reaction rather than a mixture. Rust is a compound made up of iron oxide that results from the reaction of iron with oxygen and water in the presence of air.

No, once an iron nail begins to rust, it cannot be reversed. Rust is a chemical reaction between iron, oxygen, and water, forming iron oxide. This process cannot be undone.
it can rust it reacts with atmosphere and reacts with iron oxide then it get rusted
