When you put a metal inside sulphuric acid, the metal quickly displaces the hydrogen and
forms respective metal sulphate and hydrogen gas is liberated.
But this happens in the case of reactive metals only.
In case of Mercury, Copper, Silver, Gold And Platinum no reaction occurs.
Nothing happens. Gold will not react with sulfuric acid.
Nothing, gold doesn't react with sulphuric acid
depending on the kind of acid and the metal, corrosion may occur
Magnesium metal would displace hydrogen from Sulphuric acid and form Magnesium sulphate anh Hydrogen gas would be liberated.
You'd get dilute sulfuric acid. The temperature would go up (possibly a lot), since the dissociation of sulfuric acid in water is exothermic.

Sulfuric acid is added in pools to control the pH of the water; many specialists don't recommend the use of H2SO4.
You would get a very energetic (or even explosive) reaction which would produce magnesium sulphate and hydrogen gas.
Sulfuric acid neither burns or causes a fire.

Magnesium does not seem to react with dilute aqueous alkalis or bases. However, it does react with acids like sulfuric acid by dissolving in it.
Yes, Copper oxide does fizz when it reacts with Sulphuric Acid
