 Chúc bạn học tốt

CuO + H₂SO₄ --> CuSO₄ + H₂O

CuSO4+2NaOH->Cu(OH)2+Na2SO4

Cu(OH)2+2HCl->CuCl2+2H2O

CuCl2+2NaOH->2NaCl+Cu(OH)2

A:

\(Cu\left(OH\right)_2--to->CuO+H_2O\)

\(CuO+2HCl-->CuCl_2+H_2O\)

\(CuCl_2+2NaOH-->Cu\left(OH\right)_2+2NaCl\)

\(Cu\left(OH\right)_2+H_2SO_4-->CuSO_4+2H_2O\)

B:

\(Mg\left(OH\right)_2--to->MgO+H_2O\)

\(MgO+2HCl-->MgCl_2+H_2O\)

\(MgCl_2+2NaOH-->Mg\left(OH\right)_2+2NaCl\)

\(Mg\left(OH\right)_2+H_2SO_4-->MgSO_4+2H_2O\)

A: Cu(OH)₂ \(\underrightarrow{t^o}\) CuO + H₂O

CuO + 2HCl \(\rightarrow\) CuCl₂ + H₂O

CuCl₂ +2 NaOH \(\rightarrow\) Cu(OH)₂ + NaCl

Cu(OH)₂ + H₂SO₄ \(\rightarrow\) CuSO₄ + 2H₂O

B: Mg(OH)₂ \(\underrightarrow{t^o}\) 2MgO + H₂O

MgO + 2HCl \(\rightarrow\) MgCl₂ + H₂O

MgCl₂ + 2NaOH \(\rightarrow\) Mg(OH)₂ + NaCl

Mg(OH)₂ + H₂SO₄ \(\rightarrow\) MgSO₄ + 2H₂O

Giải được câu A rồi thì câu B làm tương tự thôi

A) 1. Cu(OH)₂ \(\underrightarrow{to}\) CuO + H₂O

2. CuO + 2HCl → CuCl₂ + H₂O

3. CuCl₂ + 2NaOH → 2NaCl + Cu(OH)₂↓

4. Cu(OH)₂ + H₂SO₄ → CuSO₄ + 2H₂O

B) 1. Mg(OH)₂ \(\underrightarrow{to}\) MgO + H₂O

2. MgO + 2HCl → MgCl₂ + H₂O

3. MgCl₂ + 2NaOH → 2NaCl + Mg(OH)₂↓

4. Mg(OH)₂ + H₂SO₄ → MgSO₄ + 2H₂O

\((1)Cu+2H_2SO_{4(\text{đ})}\xrightarrow{t^o} CuSO_4+2H_2O+SO_2\uparrow\\ (2)CuSO_4+BaCl_2\to CuCl_2+BaSO_4\downarrow\\ (3)CuCl_2+2NaOH\to Cu(OH)_2\downarrow +2NaCl\\ (4)Cu(OH)_2\xrightarrow{t^o}CuO+H_2O\\ (5)CuO+H_2\xrightarrow{t^o}Cu+H_2O\)

CaO + H₂O --> Ca(OH)₂

Ca(OH)₂ + CuCl₂ --> Cu(OH)₂\(\downarrow\) + CaCl₂

Cu(OH)₂ --t^o--> CuO + H₂O

CuO + H₂SO₄ --> CuSO₄ + H₂O

CuSO₄ + Fe --> FeSO₄ + Cu\(\downarrow\)

FeSO₄ + Zn --> ZnSO₄ + Fe\(\downarrow\)
