There are two sulphides of gold - Gold(I) sulfide (Au2S) and gold(III) sulfide, (Au2S3). Gold sulphides can be prepared treating gold chloride with hydrogen sulfide or by treating dicyanoaurate: in the reaction H2S + 2 KAu(CN)2 → Au2S + 2 KCN + 2 HCN
Yes it reacts to form Iron(II) sulfate and hydrogen gas
hydrogen gasmagnesium + sulfuric acid → magnesium sulfate + hydrogen
Iron sulfate (ferrous sulfate) does not react with sulfuric acid because it is already in the form of a salt with sulfuric acid - FeSO4. However, iron metal can react with sulfuric acid to form iron sulfate and hydrogen gas.
Yes, and the results would be zinc sulfate and hydrogen.
At STP, there will be no reaction. Gold is much less active than copper so there will be negligible gold sulfate formed by substitution. Gold is the lowest metal in the electrochemical series, so it will not react chemically with salts of any other metal.
hydrogen is not a molecule.
Magnesium will react with sulfuric acid to produce magnesium sulfate.

It reacts with zinc to form zinc sulfate and hydrogen
It may be either a reactant or a product depending on what the reaction is. If you react elemental zinc with sulfuric acid to form zinc sulfate and hydrogen, then it is a product. If you react aqueous zinc sulfate with sodium hydroxide to form solid zinc hydroxide and sodium sulfate, then it is a reactant.

Metals like gold, platinum, and silver typically do not react with copper sulfate. Additionally, metal compounds that are less reactive than copper, such as zinc oxide or aluminum oxide, will not react with copper sulfate either.
No, magnesium sulfate will not react with magnesium because magnesium sulfate is a salt that dissolves in water to form magnesium ions and sulfate ions. Pure magnesium does not react with magnesium sulfate.
