I was given a homework assignment, and was asked to make and complete a chart using polyatomic ions. I don't know how to balance, or even attempt to complete it. The first one on the chart is, Cu+1 & C2H3O2-1. Please help! A website that has the steps broken down, would be great! Thanks

Cu+1 & C2H3O2-1 ---> CuC2H3O2

Cu+2 & C2H3O2-1 ---> Cu(C2H3O2)2

note the parentheses

NH4^+  and SO4^2- ---> (NH4)2SO4

Mg^2+ and PO4^3- ---> Mg3(PO4)2

Make sure to look at the two videos which have mercury in the title. The mercury +1 ion is unusual.

Hg2^2+ and NO3^- ---> Hg2(NO3)2

It is NOT reduced to HgNO3.

Hg2^2+ is considered to be a polyatomic ion.
