* Zinc is more reactive than iron. This means zinc will displace iron from its compound.

* Single displacement reaction: This reaction is a classic example of a single displacement reaction, where a more reactive element replaces a less reactive element in a compound.

The reaction:

Zn(s) + Fe(NO₃)₂(aq) → Zn(NO₃)₂(aq) + Fe(s)

Explanation:

* Zinc (Zn) is a solid metal.

* Iron nitrate (Fe(NO₃)₂) is an aqueous solution (dissolved in water).

* The reaction results in the formation of zinc nitrate (Zn(NO₃)₂) in solution and solid iron (Fe).

Observations:

* You would likely see the formation of a gray/brown solid (iron) as the zinc reacts with the iron nitrate solution.

* The solution might change color as the iron nitrate is consumed and zinc nitrate forms.

Important Note: The reaction rate will depend on the surface area of the zinc, concentration of the iron nitrate solution, and temperature.
