<u>Answer:</u> The molecular balanced equation is written below
<u>Explanation:</u>
A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The balanced chemical equation for the decomposition of bromine trifluoride follows:

By Stoichiometry of the reaction:
2 moles of bromine trifluoride produces 1 mole of bromine gas and 3 moles of fluorine gas
Hence, the molecular balanced equation is written above.
