Predict whether a reaction will occur when elemental bromine and lithium chloride are mixed.
A reaction will occur when elemental bromine and lithium chloride are mixed. Bromine is a halogen and has a high affinity for electrons, while lithium is a metal with a low electronegativity. When bromine and lithium chloride are mixed, the bromine will likely react with the lithium to form lithium bromide. This is because bromine is more reactive than chlorine and will displace it in a reaction with a less reactive metal like lithium. The overall reaction can be written as:
Br2 + 2LiCl -> 2LiBr + Cl2
Therefore, a reaction will occur when elemental bromine and lithium chloride are mixed.
