magnesium
Iron (Fe) reacts reversibly with steam to form iron(II, III) oxide, or Fe3O4, also known as magnetite.
Iron reacts with steam to give iron(III) oxide, which is yellow when hot and white when cold.
The other product of the reaction may be an oxide or hydroxide.
The white powder formed when magnesium reacts with steam is magnesium oxide.
When magnesium reacts with steam, it produces magnesium oxide (MgO) and hydrogen gas. The magnesium oxide is a white powder, and the hydrogen gas is combustible and can be ignited. This reaction is similar to the reaction of magnesium with water, but steam provides a more vigorous reaction due to the higher temperature.

Magnesium oxide (MgO) is obtained.
Magnesium reacts with steam faster than cold water because magnesium needs to burn to get magnesium oxide and to get magnesium oxide there has to be heat and since steam is already heated it doesn't need much time, but the cold water needs time to heat first to react.
The white powder formed when magnesium reacts with steam is magnesium oxide.
Iron hydroxide. Fe(OH)2 or Fe(OH)3, depending on the oxidation state of iron (ferrous = +2, ferric = +3)

This reaction is similar to the reaction of magnesium with water, but steam provides a more vigorous reaction due to the higher temperature.
The word equation is that iron or Fe reacts with steam H2O to produce iron oxide and hydrogen gas. Many metals that react with steam will give the products of the specific metal oxide and hydrogen gas.
... hydrogen gas. This is a displacement reaction in which magnesium displaces hydrogen in water to form magnesium oxide and hydrogen gas.
Hydrogen and lime Ca + 2 H2O --> H2 + Ca(OH)2
Fe is the chemical symbol for iron. When iron reacts with steam it corrodes, or rusts.
