Question

Write reduction reaction of moisture containing oxygen gas for corrosion of metal. Answer the given question in brief.

Answer 1

Answer:

4Fe+2O arrow 2Fe2O3 is the required reaction

Answer 2

Answer:

When metal reacts with the moisture containing oxygen gas then a layer of color(Brown powder is formed on iron)  powder on the surface of the metal is formed which decreases the strength ,stiffness and hardness of the metal.

So,the balance chemical equation for the metal reacting with moisture containing oxygen gas.

$4x + 3O_{2} +6H_{2} O\rightarrow  4x(OH)_{3}$

Where $x = metal$
