Question 2 Page 46 (i) - Chapter 3 Class 10 - Metals and Non-Metals

Write equations for the reactions of

(i) iron with steam

Answer

(i) Iron with steam

Iron Reacts with Steam to form Iron Oxide ₊ Hydrogen Gas. 

• This is because water is slightly ionised to give hydrogen ions (H ₊ ) and hydroxide ions (OH _- ). 
• When a reactive metal combines with this water (steam, in this case) it gives electrons to reduce the H + ions to H atoms which later form hydrogen gas .
• Essentially, Iron displaces Hydrogen from water to ferric oxide.
