svetka1574 Ba(OH)2 + 2HCl = BaCl2 + 2H2O
Ba²⁺+2OH⁻+2H⁺+2Cl⁻ = Ba²⁺+2Cl⁻+2H₂O
2H⁺+2OH⁻=2H₂O

MgCl₂+(NH₄)₂CO₃ = MgCO₃↓+2NH₄Cl
Mg²⁺+2Cl⁻+2NH₄⁺+CO₃²⁻ = MgCO₃↓+2NH₄⁺+2Cl⁻
Mg²⁺+CO₃²⁻=MgCO₃↓

FeBr₃ + 3LiOH = Fe(OH)₃↓ + 3LiBr
Fe³⁺ + 3Br⁻ + 3Li⁺ + 3OH⁻ = Fe(OH)₃↓ + 3Li⁺ + 3Br⁻
Fe³⁺ + 3OH⁻ = Fe(OH)↓

CuCl₂ + Na₂S = CuS↓ + 2NaCl
Cu²⁺+2Cl⁻+2Na⁺+S²⁻ = CuS↓ + 2Na⁺+2Cl⁻
Cu²⁺+S²⁻=CuS↓

MnCl₂+Na₂S = MnS↓+2NaCl
Mn²⁺+2Cl⁻+2Na⁺+S²⁻ = MnS↓+2Na⁺+2Cl⁻
Mn²⁺+S²⁻=MnS↓

Verified answer

Ba(OH)2 + 2HCl -> BaCl2 + 2H2O
Ba(+2) + 2OH(-) + 2H(+) + 2Cl(-) -> Ba(+2) + 2Cl(-) + 2H2O
2OH(-) + 2H(+) -> 2H2O

MgCl2 + (NH4)2CO3 -> MgCO3 + 2NH4Cl
Mg(+2) + 2Cl(-)+ 2NH4(+) + CO3(-2) -> MgCO3 + 2NH4(+) + 2Cl(-)
Mg(+2) + CO3(-2) -> MgCO3

FeBr3 + 3LiOH -> Fe(OH)3 + 3LiBr
Fe(+3) + 3Br(-) + 3Li(+) + 3OH(-) -> Fe(OH)3 + 3Li(+) + 3Br(-)
Fe(+3) + 3OH(-) -> Fe(OH)3

MnCl2 + Na2S -> MnS + 2NaCl
Mn(+2) + 2Cl(-) + 2Na(+) + S(-2) -> MnS + 2Na(+) + 2Cl(-)
Mn(+2) + S(-2) -> MnS
