Expert Solution

Step 1
Given double displacement reaction:
Ca(NO3)2 + 2NaI -----> CaI2 + 2NaNO3
Given amount of Ca(NO3)2 = 23.4 g
Moles of Ca(NO3)2 in 23.4 g = 23.4 g / molar mass
= 23.4 g/164.088 g/mol = 0.1426 moles
Amount of NaI = 98.5 g
Moles of NaI in 98.5 g = 98.5g/149.89 g/mol = 0.657 mol.
Hence, Ca(NO3)2 is a limiting reactant in this reaction.
