Question

Viết các phương trình phản ứng xảy ra cho các sơ đồ sau:

a, HCl→Cl₂→FeCl₃→NaCl→HCl→CuCl₂→AgCl

b,KMnO₄→Cl₂→HCl→FeCl₃→AgCl→Cl₂→Br₂→I₂→ZnI₂→Zn(OH)₂

viết dùm mình mình cần gấp tối nay lúc 11h giúp dùm mình

Answer 1

a_ \(2HCl-^{đpdd}\rightarrow Cl_2+H_2\)

\(\dfrac{3}{2}Cl_2+Fe-^{t^o}\rightarrow FeCl_3\)

\(FeCl_3+3NaOH\rightarrow Fe\left(OH\right)_3+3NaCl\)

\(NaCl_{\left(r,k\right)}+H_2SO_{4\left(đ,n\right)}-^{t^o}\rightarrow NaHSO_4+HCl\)

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

\(CuCl_2+2AgNO_3\rightarrow Cu\left(NO_3\right)_2+2AgCl\)

Answer 2

a_ 2HCl−đpdd→Cl2+H22HCl−đpdd→Cl2+H2

Answer 3

\(2KMnO_4+16HCl_đ-^{t^o}\rightarrow2KCl+2MnCl_2+5Cl_2+8H_2O\)

\(Cl_2+H_2-^{as}\rightarrow2HCl\)

\(6HCl+Fe_2O_3\rightarrow2FeCl_3+3H_2O\)

\(FeCl_3+3AgNO_3\rightarrow Fe\left(NO_3\right)_3+3AgCl\)

\(2AgCl-^{t^o}\rightarrow2Ag+Cl_2\)

\(Cl_2+2NaBr\rightarrow2NaCl+Br_2\)

\(Br_2+2NaI\rightarrow2NaBr+I_2\)

\(I_2+Zn-^{t^o}\rightarrow ZnI_2\)

\(ZnI_2+2NaOH_{\left(vđ\right)}\rightarrow Zn\left(OH\right)_2+2NaI\)
