Question

write equations to show action of steam on metals?​

Answer 1

Answer:

2Fe(s)+O2(g)+4H(aq)+→2Fe(aq)2++2H2O(l)

Answer 2

Answer:

Magnesium reacts very slowly with water. However, it reacts vigorously with steam:

magnesium + steam → magnesium oxide + hydrogen

Mg(s) + H2O(g) → MgO(s) + H2(g)

Metals which react with steam form the solid metal oxide and hydrogen gas.

In general, the more reactive the metal, the more rapid the reaction. Aluminium is unusual, because it is a reactive metal that does not react with water. Its surface forms a protective layer of aluminium oxide that keeps water away from the metal below.
