2hno3+3h2s --> 3s+2no+4h2o
H2SO4 + CaS = CaSO4 + H2S
ZnCl2 and H2S, be aware that H2S is extremely poisonus, at low concentrations can kill in a single or few breaths
2HCl + Na(2)S-----> H(2)S + 2NaCl
The oxidation number of sulphur in H2S is 2.
ZnCl2+H2S = ZnS=2HCl
liho+h2s=
2hno3+3h2s --> 3s+2no+4h2o
FeS + 2H+ -> Fe2+ + H2S
H2SO4 + CaS = CaSO4 + H2S
ZnCl2 and H2S, be aware that H2S is extremely poisonus, at low concentrations can kill in a single or few breaths
2HCl + Na(2)S-----> H(2)S + 2NaCl
CuCl2 + H2S --> CuS + 2HCl Yes, this is the balanced equation here.
The balanced equation is as follows: 2Ag + H2S --> Ag2S + H2
The oxidation number of sulphur in H2S is 2.
It is not using H2S gas. It is using H2O liquid.
