Answer:

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

Explanation:

#CO_3^(2-) + Zn^(2+) rarr ZnCO_3(s)darr#

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"# #Pb^(2+)#, #Hg_2^(2+)#, and #Ag^+#.

#"All sulfates are soluble, except for those of"# #Pb^(2+)#, #Ba^(2+),# and #Sr^(2+)#.

#"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.
