Well, zinc carbonate is fairly insoluble so..............

Explanation:

CO23+Zn2+ZnCO3(s)

What becomes of the acetate and potassium ions?

How did I know that zinc carbonate was insoluble? How else by learning it by rote?

All the salts of the alkali metals (and NH+4), and all the acetates are soluble.

All nitrates are soluble.

All halides are soluble except for those of Pb2+, Hg2+2, and Ag+.

All sulfates are soluble, except for those of Pb2+, Ba2+, and Sr2+.

All CARBONATES AND HYDROXIDES (except for those of
the alkali metals) ARE INSOLUBLE.

You will be given such a scheme, and the exceptions, and I suggest you learn them. You will also do these sorts of partner exchanges reactions in the lab.
