Question

Answer 1

Bài 6: 

a, \(Na_2O+H_2O\rightarrow2NaOH\)

\(Fe_2\left(SO_4\right)_3+6NaOH\rightarrow2Fe\left(OH\right)_{3\downarrow}+3Na_2SO_4\)

b, \(CuO+2HCl\rightarrow CuCl_2+H_2O\)

\(CuCl_2+2NaOH\rightarrow Cu\left(OH\right)_{2\downarrow}+2NaCl\)

c, \(2Mg+O_2\underrightarrow{t^o}2MgO\)

\(MgO+H_2SO_4\rightarrow MgSO_4+H_2O\)

\(MgSO_4+2NaOH\rightarrow Na_2SO_4+Mg\left(OH\right)_{2\downarrow}\)

\(Mg\left(OH\right)_2+2HCl\rightarrow MgCl_2+2H_2O\)
