Question

Решить цепочку реакций
Zn - H2 - H2O - LiOH - Ni(OH)2 - NiO - Ni - Hg - HgO - HgSO4

Answer 1

Zn + 2HCl -> ZnCl2+H2
2H2+O2-> 2H2O
L2O+H2O-> 2LiOH
2LiOH+Ni(NO3)2-> Ni(OH)2 + 2LiNO3
Ni(OH)2-> NiO+H2O
NiO+H2-> Ni+H2O
Ni + Hg(NO3)(2-> Ni(NO3)2+Hg
2Hg+O2-> 2HgO
HgO + H2SO4-> HgSO4 + H2O

Answer 2

$Zn + H_{2}SO_{4} = ZnSO_{4} + H_{2}$
$2H_{2}+O_{2} = 2H_{2}O$
$2Li + 2H_{2}O = 2LiOH + H_{2}$
$2LiOH + NiSO_{4} = Li_{2}SO_{4} + Ni(OH)_{2}$
$Ni(OH)_{2} = NiO + H_{2}O$ (реакция при температуре)
$NiO+C=Ni + CO$
$Ni + HgSO_{4} = NiSO_{4} + Hg$
$2Hg + O_{2} = 2HgO$ (реакция при тем-ре)
$HgO+SO_{3}=HgSO_{4}$
