No precipitate will form.
This looks like a possible double replacement reaction
So the likely equation for your reaction is
CaS(aq) + 2LiNO₃(aq) → 2LiS(?) + Ca(NO₃)₂(?)
To decide if a precipitate forms, we have to review the Solubility Rules".
The two important ones for this question are:
- All compounds of Group 1 elements are soluble.
- All nitrate (NO₃⁻), chlorate (ClO₃⁻), perchlorate (ClO₄⁻), and acetate (C₂H₃O₂⁻) salts are soluble.
LiS is soluble (Rule 1).
Ca(NO₃)₂ is soluble (Rule 2).
No precipitate will form.
