Question

Lập PTHH theo các sơ đồ sau :

1) H2SO4 + NaOH - -> Na2SO4 + H2O

2) H2SO4 + Mg(OH)2 - -> MgSO4 + H20

3) HNO3 + Zn(OH)3 - -> Zn(NO3)2 + H2O

Answer 1

1) H₂SO₄ + 2NaOH -> Na₂SO₄ + 2H₂O.
2) H₂SO₄ + Mg(OH)₂-> Mg(OH)₂ +2H₂O.
3)2HNO₃ + Zn(OH)₃ -> Zn(NO3)₂ + 2H₂O.

Answer 2

1. \(H_2SO_4\)+ NaOH --> \(Na_2SO_4\)+ \(H_2O\)
\(H_2SO_4\)+ 2NaOH --> \(Na_2SO_4\)+\(H_2O\)
\(H_2SO_4\)+ 2NaOH \(\rightarrow\) \(Na_2SO_4\)+2\(H_2O\)
2. \(H_2SO_4\)+ \(Mg\left(OH_2\right)\)--> \(MgSO_4\)+\(H_2O\)
\(H_2SO_4\)+\(Mg\left(OH_2\right)\)\(\rightarrow\) \(MgSO_4\)+2\(H_2O\)
3. \(HNO_3\)+\(Zn\left(OH\right)_3\)-->\(Zn\left(NO_3\right)_2\)+\(H_2O\)
2\(HNO_3\)+\(Zn\left(OH\right)_3\)-->\(Zn\left(NO_3\right)_2\)+\(H_2O\)
2\(HNO_3\)+\(Zn\left(OH\right)_3\)\(\rightarrow\)\(Zn\left(NO_3\right)_2\)+2\(H_2O\)
