Answer:

calcium chloride and silver nitrate

Explanation:

A precipitate is often formed in a double replacement reaction when the reaction yields an insoluble product.

Consider the reaction between calcium chloride and silver nitrate;

CaCl2(aq) + 2AgNO3(aq) -------->2AgCl(s) + Ca(NO3)2(aq)

AgCl is insoluble in water, hence the reaction leads to the formation of a precipitate.

maks197457 [2]
the complete question in attached figure

Let 
x------------------- >  actual yield
y------------------- > theoretical yield 
z------------------- > percent yield
we have that
z=x/y

we know
x=47 g
y=56 g

therefore

z=47/56=0.839 ---------------- > 83.9%

the answer is the option C 83.9%
