Question

FeS + HCL (dd) —---->

CuS + HCL (dd) —---->

CaCo3 + HCL (dd) —--->

MnO2 + HCL (nae) —--->

NaCl (dd) AgNO3 (dd)------->

HCL (dd) AgNO3 (dd)------>

Answer 1

\(FeS+2HCl\rightarrow FeCl_2+H_2S\)

\(CuS+HCl\rightarrow\) không phản ứng

\(CaCO_3+2HCl\rightarrow CaCl_2+CO_2+H_2O\)

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

\(NaCl+AgNO_3\rightarrow AgCl\downarrow+NaNO_3\)

\(HCl+AgNO_3\rightarrow AgCl\downarrow+HNO_3\)

Answer 2

FeS + 2HCL (dd) —---->FeCl2+H2S

CuS + 2HCL (dd) —---->X

CaCo3 + HCL (dd) —--->CaCl2+H2O+CO2

MnO2 + 4HCL (nae) —--->MnCl2+Cl2+2H2O

NaCl (dd) AgNO3 (dd)------->AgCl+NaNO3

HCL (dd) AgNO3 (dd)------>AgCl+HNO3
