Question

what happens when iron (fe)reacts with air and water

Answer 1

When iron reacts with air and water , the rusting happens

Answer 2

Reaction of iron with water. ... However, iron metal reacts in moist airby oxidation to give a hydrated ironoxide. This does not protect the ironsurface to further reaction since it flakes off, exposing more iron metal to oxidation. This process is called rusting and is familiar to any car owner.Air-free water has little effect upon ironmetal. However, iron metal reacts in moist air by oxidation to give a hydrated ironoxide. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. This process is called rusting and is familiar to any car owner.

Fe + H2O —— Fe3O4 + H2

Iron very inactive with water but at high temperature it gets reacted with hot water or steam.When glowing hot iron is placed in very hot water it releases hydrogen gas and forms ferric oxide(Fe3O4
