When iron is added to gold nitrate solution, no reaction occurs because iron is not reactive enough to displace gold from its nitrate compound. Gold nitrate would remain unchanged.
When solid zinc reacts with aqueous gold(III) nitrate, zinc displaces gold in the compound through a single displacement reaction. The products of the reaction are gold metal and aqueous zinc nitrate.
When a gold ring is dropped into a solution of copper nitrate, a redox reaction takes place where the gold would dissolve as gold ions, and copper from the copper nitrate would deposit onto the ring. This results in the gold ring becoming plated with a layer of copper.
Yes, gold does react with nitric acid to form gold nitrate. This reaction is often used to test the purity of gold because impure gold will react differently.
Gold (III) nitrate has the formula Au(NO3)3.
Gold nuggets can turn black due to a process called tarnishing, which is the result of a chemical reaction between the gold and sulfur or other compounds in the environment. This tarnishing can darken the surface of the gold nugget, but it does not affect the actual composition or value of the gold.

it can etch gold
Silver is slightly more reactive than gold, although they are both very unreactive. Assuming that the gold nitrate exists, because it would be very rare, silver would react with it and displace it. The products formed will be silver nitrate and gold.

The ionic formula for gold(II) nitrate is Au(NO3)2.
Just gold and nitric acid. Gold's impervious to nitric acid.
Any reaction between gold and air at room temperature.
The nitrate anion is a large, monovalent moiety. Gold is also a fairly large cation, so, although the charge is +1, the effective attraction over that distance is somewhat lessened. These two factors make it easy for a polar solvent (like water) to separate gold nitrate into its respective ionic species. For the record, I cannot think of a single non-soluble nitrate compound.
The molecular formula for gold nitrate is Au(NO3)3.
