When iron (Fe) reacts with silver nitrate (AgNO₃), a single displacement reaction occurs, resulting in the formation of silver (Ag) and iron(II) nitrate (Fe(NO₃)₂) .

Here's the balanced chemical equation:

Fe(s) + 2AgNO₃(aq) → 2Ag(s) + Fe(NO₃)₂(aq)

Explanation:

* Iron is more reactive than silver.

* This means iron will displace silver from its compound, silver nitrate.

* Iron reacts with the nitrate ions (NO₃⁻) to form iron(II) nitrate.

* The displaced silver atoms combine to form metallic silver, which precipitates out of the solution.

Observations:

You will observe the following:

* The iron metal will gradually disappear as it reacts.

* A shiny, silvery solid (metallic silver) will form on the surface of the iron.

* The solution will turn a pale green due to the formation of iron(II) nitrate.
