Final answer:
The correct balanced equation for the reaction is Ca(NO3)2(aq) + 2AgCl(s).
Step-by-step explanation:
This balanced equation, derived in the usual fashion, is called a molecular equation because it doesn't explicitly represent the ionic species that are present in solution. When ionic compounds dissolve in water, they may dissociate into their constituent ions, which are subsequently dispersed homogenously throughout the resulting solution (a thorough discussion of this important process is provided in the chapter on solutions). Ionic compounds dissolved in water are, therefore, more realistically represented as dissociated ions, in this case: Ca(NO3)2(aq) + 2AgCl(s)
