Question

mn ơi tui đang cần gấp lắm bài này

Viết pt theo sơ đồ:

CuO--->CúO4--->CuSO3--->CuCL2--->Cu(NO3)2--->Cu

ZnCO3--->ZnCL2--->Zn(OH)2--->ZnO--->ZnSO4--->Zn(NO302

FeCL3--->Fe(OH)3--->FeCL3--->Fe--->FeSO4--->Fe(MO3)2

Answer 1

$CuO + H_2SO_4 \to CuSO_4 + H_2O$

Không thể từ $CuSO_4 \to CuSO_3$

$CuSO_3 + 2HCl \to CuCl_2 + SO_2 + H_2O$

$CuCl_2 + 2AgNO_3 \to 2AgCl + Cu(NO_3)_2$

$Fe +Cu(NO_3)_2 \to Fe(NO_3)_2 + Cu$

$ZnCO_3 + 2HCl \to ZnCl_2 + CO_2 + H_2O$

$ZnCl_2 + 2KOH \to Zn(OH)_2 + 2KCl$

$Zn(OH)_2 \xrightarrow{t^o} ZnO + H_2O$

$ZnO + H_2SO_4 \to ZnSO_4 + H_2O$

$ZnSO_4 + Ba(NO_3)_2 \to BaSO_4 + Zn(NO_3)_2$

$FeCl_3 + 3KOH \to Fe(OH)_3 + 3KCl$

$Fe(OH)_3 + 3HCl \to FeCl_3 + 3H_2O$

$2FeCl_3 + 3Mg \to 3MgCl_2 + 2Fe$

$Fe + H_2SO_4 \to FeSO_4 + H_2$

$FeSO_4 + Ba(NO_3)_2 \to BaSO_4 + Fe(NO_3)_2$
