Answer:

When aqueous solutions of silver(I) acetate and manganese(II) iodide are combined, an insoluble precipitate of silver(I) iodide is formed

Explanation:

It is an example of precipitation reaction.
When aqueous solutions of silver(I) acetate and manganese(II) iodide are combined, an insoluble precipitate of silver(I) iodide is formed.
Precipitation of silver(I) iodide is confirmed by it's yellow color.
Hence a reaction is observed.
Molecular reaction: $2Ag(OAc)(aq.)+MnI_{2}(aq.)\rightarrow 2AgI(s)+Mn(OAc)_{2}(aq.)$
