iron reacts with oxygen in the air to produce iron oxide which is basically rust. however it can only do this in the presence of water. salt will speed up the reaction
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
Metals like copper, silver, and gold do not react with cold water because they are less reactive. This is due to their position in the reactivity series, where they do not displace hydrogen from water.
Gold does not react with water or steam. i wouldn't totally agree with the above statment. There are 5 metals which don't not just 1...these are: .lead .copper .mercury .silver .gold
Iron will react with water and oxygen to produce rust. Essentially water has oxygen atoms in it so as long as iron is in contact with water, it will rust.
Iron oxide does not react with water under normal conditions. However, in the presence of certain catalysts or at high temperatures, it can react with water to form iron hydroxide.
Iron will slowly rust in cold water.
Iron and Zinc
No, only calcium very slowly in steaming water
Iron does not react with water because the hydrogen and Oxygen are already combined. Also Hydrogen is an Akaline metal which means no other metal could take its place.

alkali metals react violently in cold water
Potassium react violent with water, iron react only if oxygen is present.
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
