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
2Mg+O2--> 2MgO(1)
MgO+2HCl-->MgCl2+H2O(2)
MgCl2+2NaOH--> Mg(OH)2+2NaCl(3)
Mg(OH)2+CuSO4-->MgSO4+Cu(OH)2(4)
MgSO4+Ba(NO3)2-->Mg(NO3)2+BaSO4(5)
CuO+H2SO4-->CuSO4+H2O(1)
CuSO4+2NaOH-->Cu(OH)2+Na2SO4(2)
Cu(OH)2+2HCl-->CuCl2+2H2O(3)
CuCl2+2AgNO3-->Cu(NO3)2+2AgCl(4)
Cu(NO3)2+Mg-->Mg(NO3)2+Cu(5)

(44) Fe2(SO4)3 + Fe → 3FeSO4
(45) 3FeSO4 + 2Al(OH)3 → Al2(SO4)3 + 3Fe(OH)2↓
(46) FeSO4 + 2NaOH → Na2SO4 + Fe(OH)2↓
(48) Al(OH)3 + NaOH → NaAlO2 + 2H2O
(49) 2NaAlO2 + 3H2O + CO2 → 2Al(OH)3↓ + Na2CO3
(50) CO2 + 3H2O + 2NaAlO2 → 2Al(OH)3↓ + Na2CO3
(51) 4Fe(OH)2 + O2 + 2H2O \(\underrightarrow{to}\) 4Fe(OH)3
(52) 2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O
34. MgSO4 + BaCl2 -> BaSO4 + MgCl2
35. MgCl2 + 2NaOH -> 2NaCl + Mg(OH)2
