The reaction is:
BaS + K2CO3 = BaCO3(s) + K2S
aqueous strontium sulfide
This compound is potassium sulfide - K2S.
The chemical equation Mg + H2S -> MgS + H2.
strontium sulfide
Potassium hydrogen sulfide is KHS. (In KHS or KSH you could replace an S by an O atom to get KOH called hydro-oxide or shortened hydroxide)
Potassium has a formal charge of +1, and sulfide has a formal charge of -2, so: K2S
The chemical symbol for Potassium Sulphate is K2SO4
K2s
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
I assume a double displacement reaction. At least ideally. 2KI + CaS -> K2S + CaI2
aqueous strontium sulfide
This compound is potassium sulfide - K2S.
The hydrogen sulfide is H2S.
Potassium is in group one, so according to solubility rules, it will aways be soluble and therefore a spectator ion. That means that it will not take part in the chemical reaction and in a net equation it would not have to be included. HgCl2 + K2S yields HgS + 2KCl(aquious)
Formula for potassium sulfide is K2S.
Potassium sulfide
K2S-Potassium Sulfide!!! HOPE THAT HELPS!!! kuz i got an A for that answer!!!
