我想問下以下化學反應

NaCl is stable in the mixture, and does not react.

Copper is an unreactive metal which does not react with acid.

Iron is the reactive enough to react with CH3COOH to give hydrogen gas and iron(II) ethanoate solution. This is the only reaction in the mixture.
2CH3COOH(aq) + 2Fe(s) → (CH3COO)2Fe(aq) + H2(g)

The sodium chloride will remain stable, where in aq solution, Na+ and Cl- will remain in the system.

For the rest, metal plus acid will give you salt and hydrogen, so you will get the Corresponding iron salt, copper salt, and hydrogen.

I have a feeling that copper will not react with the carboxylic acid, you will need to check for the free energy to see if this reaction would take place!

By the way, when they all mix together, the system will have Na+, Fe2+, Fe3+, Cu2+, H2, Cl- and CH3COO-.
