When iron gets in contact with oxygen (or water, which also contains oxygen) it starts giving electrons to the oxygen atoms, in a process called oxidisation, and when that occurs, iron oxide ( $Fe_2 O_3$ ) is made.

Note: iron oxide is what we call rust. And, iron is so easy to rust because it usually isn't mixed with any other protective metals or covered in protective films.

Hope it helped,

The process of foam formation is thus through a dispersed medium and in general gas is present.

The foam is thus evidence that respiration, is taking place as carbon dioxide is a product of respiration.
