Here's how to write the word equation for the reaction between iron(III) nitrate and copper:

Iron(III) nitrate + Copper → Iron + Copper(II) nitrate

Explanation:

* Iron(III) nitrate: This is the reactant containing iron in a +3 oxidation state.

* Copper: This is the other reactant, a pure metal.

* Iron: This is the product formed when the iron in the nitrate compound is reduced.

* Copper(II) nitrate: This is the product formed when the copper is oxidized.

Important Note: This reaction actually occurs because copper is more reactive than iron. This means copper can displace iron from the nitrate compound.
