The chemical symbols that will complete the equation for this single displacement reaction are 2NaCl + Br₂.
The balanced equation for the above-mentioned reaction is as follows;
2NaBr + Cl₂ → 2NaCl + Br₂
When an element reacts with a compound and replaces another element in that molecule, the reaction is known as a single displacement reaction. In most cases, the element with a higher degree of reactivity will drive out the elements with a lower degree of reactivity from its complex. As a result of the higher reactivity of chlorine (Cl₂) compared to bromine (Br₂), bromine gets displaced from its compound by chlorine.
