Question

Complete the following reaction:

${\mathrm{Cl}}_2+\mathrm{NaBr}\stackrel{}{\to }----+{\mathrm{Br}}_2$

Answer 1

Displacement reaction:

• It is a chemical reaction in which an element replaces another element in a compound and takes its place.
• $\underset{\mathrm{Chlorine}\mathrm{gas}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Sodium}\mathrm{bromide}}{2\mathrm{NaBr}\left(\mathrm{aq}\right)}\stackrel{}{\to }\underset{\mathrm{Sodium}\mathrm{chloride}}{2\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Bromine}\mathrm{gas}}{{\mathrm{Br}}_2\left(\mathrm{g}\right)}$
• It is a displacement of a less reactive non-metal by a more reactive non-metal.
