Answer 1

Answer:

iron combines with oxygen and water vapour of air to form rust - True

Answer 2

Answer :

Iron combines with oxygen and water vapour of air to form rust state ➠ True

★ Corrosion :

The slow eating away of metals when exposed to the atmosphere is called corrosion$.$

Corrosion of Iron (Rusting) : It is an electrochemical phenomenon which occurs in the presence of moisture and oxygen.

At anode :

• Fe → Fe$^{+2}$ + 2e‾

At cathode :

• O₂ + 4H$^+$ + 4e‾ → 2H₂O

Overall reaction :

• 2Fe + O₂ + 4H$^+$ → 2Fe$^{+2}$ + 2H₂O

Method used for prevention of corrosion are barrier protrction, sacrificial protection, anti-rust solutions.
