Chemical equations depict the elements and compounds with their coefficients and illustrate the reactants and the products of a reaction.
The best that completes the reaction is:
Option A. No reaction
The reaction can be explained as:
- This reaction can be a single replacement reaction in which [tex]\rm Br_{2}[/tex] and [tex]\rm NaF[/tex] are the reactants and will produce products by replacing single elements. The reactants react to give products of this equation to be [tex]\rm NaBr[/tex] and [tex]\rm F_{2}[/tex].
- But the reaction will not occur due to the property of reactivity. In the group from the top towards the bottom the reactivity decreases.
- In the group, fluorine is placed above bromine and is more reactive compared to [tex]\rm Br[/tex]. Hence bromine cannot replace fluorine from the reactant and no reaction will take place.
Therefore, no reaction occurs.
