I know that when CaCl2 and AgNO3 combine, a single displacement reaction occurs and a precipitate forms. However, it is asked to explain something else (possibly something unique?) about this reaction, and so far I haven't been able to find any information about it.

mirsolav - probably a mistype, but "single" displacement?  Did you mean double displacement (or replacement) with AgCl being the precipitate?

As for your question, give us a little hint on what you are current studying.  We can then use that to help provide a more accurate answer.

I am not sure what you meant by displacement reaction. As far I can tell you, AgCl is defnitely precipitated because it's insoluble in water. Precipitation occurs when the ionic product of the salt constituent exceed its solubility product.
