Answer:
Explanation:
Here, we want to get the resulting products from the combination of the reactants
The products formed are sodium chloride and calcium sulfide
The calcium sulfide is insoluble and it is the precipitate formed
We have the equation of reaction as follows:
[tex]Na_2S_{(aq)}+CaCl_{2(aq)}\text{ }\rightarrow CaS_{(s)}+2NaCl_{(aq)}[/tex]
