#"Cl"_2("g") + "2NaBr(aq)"##rarr##"Br"_2(l) + "2NaCl(aq)"#

Explanation:

Balanced equation

#"Cl"_2("g") + "2NaBr(aq)"##rarr##"Br"_2(l) + "2NaCl(aq)"#

This is a single replacement reaction involving halides (group 17/VIIA). Whether this reaction will actually occur depends on the position of #"Cl"# and #"Br"# on the periodic table. The order of reactivity goes from the highest reactivity in fluorine at the top, to the lowest reactivity in astatine at the bottom. Since chlorine is above bromine, it will replace the bromine to form #"NaCl"# and #"Br"_2"#.
