Question

iron[fe]+oxygen[o2]+water[h2o]gives----------------------------

Answer 1

Answer:

oh please follow me?

Explanation:

Iron nails are immersed in copper sulphate solution , the nails got coated with a metal.

When Iron nails are sunk in the copper sulphate solution, the iron reacts with the sulphate ion and displaces copper, then forms Iron sulphate.

This is an example of Chemical displacement reaction.

"The reaction in which a high reactive metal displaces less reactive metal (when compared with it) in its aqueous solution is called Chemical displacement reaction".

After this reaction, a brown layer of copper is formed on the nail.

Required chemical equation :

\sf \large{ {CuSO _{4}} _{(aq)} + Fe _{(s)} \longrightarrow \: {FeSO _{4} }_{(aq)} + Cu_{(s)}}CuSO

4

(aq)

+Fe

(s)

⟶FeSO

4

(aq)

+Cu

(s)

Hence, the layer of the metal formed on the nail is Copper.
