Объяснение:
1.
Zn + Cl2 = ZnCl2
ZnO + 2HCl = ZnCl2 + H2O
Zn(OH)2 + 2HCl = ZnCl2 + 2H2O
Zn + 2HCl = ZnCl2 + H2
ZnSO4 + BaCl2 = ZnCl2 + BaSO4↓
2.
a) CaBr2 + K2CO3 = 2KBr + CaCO3 ↓
b) ZnCl2 + 2NaOH = 2NaCl + Zn(OH)2 ↓
в) BaO + 2HCl = BaCl2 + H2O
г) Cu(OH)2 + H2SO4 = CuSO4 + 2H2O
д) MgO + SiO2 = MgSiO3
е) Mg + 2HBr = MgBr2 + H2
є) Ca + Cl2 = CaCl2
