Question

hoàn thành PTHH sảy ra khi cho axit HCL Tác dụng với a . d. fe(OH)3,Zn(OH)2 e. MnO2,KMnO4

Answer 1

\(3HCl+Fe\left(OH\right)_3\rightarrow FeCl_3+3H_2O\\ 2HCl+Zn\left(OH\right)_2\rightarrow ZnCl_2+2H_2O\\ 4HCl+MnO_2\rightarrow^{t^o}MnCl_2+Cl_2+2H_2O\\ 16HCl+2KMnO_4\rightarrow2KCl+2MnCl_2+5Cl_2+8H_2O\)

Answer 2

d)\(Fe\left(OH\right)_3+3HCl\rightarrow FeCl_3+3H_2O\)

   \(Zn\left(OH\right)_2+2HCl\rightarrow ZnCl_2+2H_2O\)

e)\(MnO_2+4HCl\rightarrow MnCl_2+2H_2O+Cl_2\uparrow\)

   \(2KMnO_4+16HCl\rightarrow2KCl+2MnCl_2+5Cl_2+8H_2O\)
