Каля · Answer 1

K + H2S = K2S + H2

K2S + H2S = 2KHS

KHS + KOH = K2S + H2O

K2S + CuCl2 = CuS + 2KCl

CuS + O2 = CuO + SO2

ZnO + SO2 = ZnSO3

ZnSO3 = ZnO + SO2 прокаливание

Аввакум · Answer 2

H2S+K2SO4=K2S+H2SO4

K2S+H2S=2KHS

KHS+KOH=K2S+H2O

K2S+CuSO4=K2SO4+CuS

2CuS+3O2=2SO2+2CuO

SO2+ZnO=ZnSO3

ZnSO3+H2SO4=SO2+ZnSO4+H2O

H2 S → K2S → KHS → K2S → CuS → SO2→ ZnSO3 → SO2;

H2 S → K2S → KHS → K2S → CuS → SO2

→ ZnSO3 → SO2;
