Hey I'm but a simple chem student but I think the reaction is this. 2C2H3O2 + Cu = Cu(C2H3O2)2. This reaction yields Copper Acetate(WSDTY), again I'm not sure.I couldn't get the subscript to work so all of the numbers are subscript except for the 2 on the very left. That is a coefficient that is balancing the reaction.

What happens is the Copper with a charge of 2+ and the Acetic acid with a charge of 1- form a compound. Because of their charges there must be two molecules of Acetic acid. Again I'm not sure if this correct but there you go.Just thought that I would add that the Reaction between Acetic Acid and Copper will create not only Copper acetate but also Hydrogen. Water and salt are produced as reactants in an Acid/Base reaction. An acid/metal reaction will usually involve some sort of ionic reaction with H2 as a product. Therefore, the following equation is correct: 2HC2H302 + Cu = Cu(C2H3O2)2 +H2
