Although the process of rusting does release heat, the precess itself is very slow, so the rate at which the heat is released does not produce a noticeable change in temperature.
A rusty nail is metallic because it is made of iron, which is a metal. The rust, formed from the oxidation of iron, is a nonmetallic compound (iron oxide), but the nail itself retains its metallic properties despite being rusty.
rusting of nails is a chemical reaction. iron combines with oxygen to form iron oxide which is rust. water/water vapour acts as a catalysthere.
Iron lose electrons.
Only one metal can rust, so the question refers to iron.
The chemical property in which iron has the ability to react with oxygen to form iron oxide (rust).
Steel or iron goes rusty in water.

Iron is a good conductor of heat, so when you touch an iron railing, it can quickly draw heat away from your hand, making it feel cold. Additionally, iron can also feel cold because it is often exposed to the outdoor environment, which can make it cooler to the touch compared to other materials.
They are made out of iron
If they have iron oxide on them.
Only those coins made from iron or an iron alloy, and that are rusty.

Rusty iron no longer can conduct electricity because it is corroded, or it reacts chemically to form a compound that weakens it.
Iron needs oxygen and water to rust. When iron is exposed to air and moisture, a chemical reaction occurs, forming iron oxide (rust) on the surface of the metal. This process is accelerated in the presence of salt or acids.
No, a rusty iron nail is not a homogeneous mixture. It is a chemical compound made up of iron and oxygen that has undergone oxidation, causing it to form rust.
