Write a word equation for the reaction between lithium bromide and chlorine gas.

This is a displacement reaction as the more reactive halogen (chlorine) will displace the halide ion from the ionic compound (lithium bromide). This will result in the bromide being displaced and forming bromine while the chlorine joins with the lithium to form lithium chloride. The word equation is lithium bromide + chlorine -> lithium chloride + bromine.
