Nastasia [14]

<u>Answer:</u> The balanced chemical equation is written below.

<u>Explanation:</u>

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

AB+CD\rightarrow CB+AD

When sodium permanganate reacts with iron (III) chloride, it leads to the production of sodium chloride and iron (III) permanganate.

The chemical equation for the reaction of sodium permanganate and iron (III) chloride follows:

3NaMnO_4(aq.)+FeCl_3(aq.)\rightarrow Fe(MnO_4)_3(s)+3NaCl(aq.)

By Stoichiometry of the reaction:

3 moles of aqueous solution of sodium permanganate reacts with 1 mole of aqueous solution of iron (III) chloride to produce 1 mole of solid iron permanganate and 3 moles of aqueous solution of sodium chloride

Hence, the balanced chemical equation is written above.
