2AlBr_3 + 3Cl_2 -> 2AlCl_3 + 3Br_22AlBr3+3Cl22AlCl3+3Br2

Explanation:

Translate names to symbols
AlBr_3 + Cl_2 -> AlCl_3 + Br_2AlBr3+Cl2AlCl3+Br2
Balance Cl and Br by adding atoms
AlBr_3 + 3/2Cl_2 -> AlCl_3 + 3/2Br_2AlBr3+32Cl2AlCl3+32Br2
Multiply by 2 to get to the nearest whole number
2AlBr_3 + 3Cl_2 -> 2AlCl_3 + 3Br_22AlBr3+3Cl22AlCl3+3Br2
