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
