Verified answer

NaOH + MgO ≠

Zn + 2HCl = ZnCl2 + H2↑
Zn + 2H⁺ + 2Cl⁻ = Zn²⁺ + 2Cl⁻ + H₂↑
Zn + 2H⁺ = Zn²⁺ + H₂↑

CuO + 2HNO3 = Cu(NO3)2 + H2O
CuO + 2H⁺ + 2NO₃ = Cu²⁺ + 2NO₃ + H₂O
CuO + 2H⁺ = Cu²⁺ + H₂O

H2SO4 + BaCl2 = BaSO4↓ + 2HCl
2H⁺ + SO₄²⁻ + Ba²⁺+2Cl⁻ = BaSO₄↓ + 2H⁺ + 2Cl⁻
Ba²⁺ + SO₄²⁻ = BaSO₄↓

NaOH + HBr = NaBr + H2O
Na⁺+OH⁻ + H⁺+Br⁻ = Na⁺+Br⁻ + H₂O
H⁺+ OH⁻ = H₂O

Alexei78 NaOH+MgO≠

Zn+2HCL-->ZnCL2+H2↑
Zn°+2H⁺+2CL⁻-->Zn²⁺+2CL⁻+H⁰₂
Zn⁰+2H⁺-->Zn²⁺+H⁰₂

CuO+2HNO3-->Cu(NO3)2+H2O
CuO+2H⁺+2NO⁻₃-->Cu²⁺+2NO⁻₃+H2O
CuO+2H⁺-->Cu²⁺+H2O

H2SO4+BaCL2-->2HCL+BaSO4↓
2H⁺+SO²⁻₄+Ba²⁺+2CL⁻-->2H⁺+2CL⁻+BaSO4
SO²⁻₄+Ba²⁺-->BaSO₄

NaOH+HBr-->NaBr+H2O
Na⁺+OH⁻+H⁺+Br⁻-->Na⁺+Br⁻+H2O
OH⁻+H⁺-->H2O
