Question

Запишите уравнения возможных реакций :
HgCl₂+Fe=
CuCl₂+Al=
AgNO₃+Zn=
ZnCl₂+Fe=
AgNO₃+Au=
Cu+H₂SO₄(разб)=
Ag+HCl=

Answer 1

$HgCl_2 + Fe = FeCl_2 + Hg; \ 3CuCl_2 + 2Al = 2AlCl_3 + 3Cu; \ AgNO_3 + Zn = Zn(NO_3)_2 + Ag; \ ZnCl_2 + Fe neq; \ AgNO_3 + Au neq; \ Cu + H_2SO_4 = CuO + SO_2 + H_2O; \ Ag + HCl neq.$
