First there is no AuO2. Gold has max 3+ in oxidation number.

And hydrogen can also not developed.

And please dont write these nonse equations in future.
There is no balance and also no right components either right reactions.

Getting Au from what. Normally Au existing as element already. You have to clean it from the other stuff. normaly used Cyanide or mercury, very Poisson procedure. HCl cannot dissolve Au. But its able to dissolve other metals and their oxides.

This is to calculate molecular mass, but it doesn't show, if the compound is existing. You can type in what you want.

Ag2(NO3)2 is also not existing.

Discussion makes no sense. or show me a literate place where you can find more information about it.

I would say no. How this molecule should looks like. maybe (HNO3)2 but no H2(NO3)2

Better write structure formula, so nobody knows what it should be.

Its not a real reaction. Because its aquaeous solution you will find Al3+ , H+, Cl- and SO4 2ä in it.

Error in the formulas.

it should be CH3CHOHCH3 2-Propanol

it can be oxidised with dichromate or Permanganate

and get CH3C=OCH3 acetone.

You didn't answer my question. What is your key target. You want to remove gold from an ore? Your Ore is FeO*Cr2O3*Au?

If this is the case I would use HCl.
