Question

CÂU 2; Thực hiện chuổi phản ứng sau: Cl2-->KClO3-->KCl-->HCl-->Cl2-->CaCl2-->Ca(NO3)2 CÂU 3; Thực hiện chuổi phản ứng sau: KMnO4-->Cl2-->HCl-->FeCl2-->NaCl-->HCl-->CuCl2-->AgCl-->Ag.

Answer 1

Câu 2:

\(3Cl_2+6KOH\underrightarrow{t^o}5KCl+KClO_3+3H_2O\)

\(2KClO_3\underrightarrow{t^o}2KCl+3O_2\uparrow\)

\(KCl_{\left(r\right)}+H_2SO_{4\left(đ/n\right)}\rightarrow KHSO_4+HCl\uparrow\)

\(MnO_2+4HCl\underrightarrow{t^o}MnCl_2+Cl_2\uparrow+2H_2O\)

\(Ca+Cl_2\rightarrow CaCl_2\)

\(CaCl_2+2AgNO_3\rightarrow Ca\left(NO_3\right)_2+2AgCl\downarrow\)

Câu 3:

\(2KMnO_4+16HCl\rightarrow2MnCl_2+2KCl+5Cl_2\uparrow+8H_2O\)

\(H_2+Cl_2\underrightarrow{as}2HCl\)

\(Fe+2HCl\rightarrow FeCl_2+H_2\uparrow\)

\(FeCl_2+2NaOH\rightarrow Fe\left(OH\right)_2\downarrow+2NaCl\)

\(NaCl_{\left(r\right)}+H_2SO_{4\left(đ/n\right)}\rightarrow NaHSO_4+HCl\uparrow\)

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

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

\(2AgCl\underrightarrow{as}2Ag+Cl_2\uparrow\)

Answer 2

Câu 2:

\(\left(1\right)3Cl_2+6KOH\overset{t^o}{--->}5KCl+KClO_3+3H_2O\)

\(\left(2\right)2KClO_3\overset{t^o}{--->}2KCl+3O_2\uparrow\)

\(\left(3\right)\cdot\cdot\cdot\cdot\cdot\cdot\cdot\)

\(\left(4\right)4HCl+MnO_2--->MnCl_2+2H_2O+Cl_2\uparrow\)

\(\left(5\right)Cl_2+Ca\overset{t^o}{--->}CaCl_2\)

\(\left(6\right)CaCl_2+2AgNO_3--->Ca\left(NO_3\right)_2+2AgCl\downarrow\)
