Zn + 2HBr -> ZnBr2 + H2⬆️
Ag + HBr -×->
Ba + 2HBr -> BaBr2 + H2⬆️
Правда, реакция в водном растворе пойдет так:
Ba(OH)2 + 2HBr -> BaBr2 + 2H2O
Cu + HBr -×->
ZnO + 2HBr -> ZnBr2 + H2O
CuO + 2HBr -> CuBr2 + H2O
P2O5 + HBr -×->
SO2 + HBr -×->
HCl + HBr -×->
H3PO4 + HBr -×->
Cu(OH)2 + 2HBr -> CuBr2 + 2H2O
NaOH + HBr -> NaBr + H2O
BaCl2 + HBr -×->
AgNO3 + HBr -> AgBr⬇️ + HNO3
Na2CO3 + 2HBr -> 2NaBr + H2O + CO2⬆️
