Copper obviously
Cu + Br2 = CuBr2
CuO? A few ways to balance it:
CuO + H2O + 2 Br2 = CuBr2 + 2HBrO (CuO is a weak base, HBrO a weak acid, so copper hypobromite not expected)
6CuO + 6Br2 = 5CuBr2 + Cu(BrO3)2

Elemental bromine is nasty as hell and you need special respirator for it! One nice property of bromine is in when added to an excess of strong
ammonia solution, it is taken up to form clear ammonium bromide solution and nitrogen gas via the reaction: 3 Br2 +2 NH3 > N2+ 6HBr. As you can
see the need for excess ammonia as if not dangerous nitrogen tribromide could form! Anyways not only is this a safe way to neutralize bromine, it
creates useful ammonium bromide which is de facto hydrobromic acid in solid form. You should be able to heat copper oxide with ammonium bromide to
get cupric bromide.
