An explosion
Sulfuric acid would do nothing to gold, even when heated. Gold is completely invulnerable to acid corrosion, with only aqua regia as an expection.
Gold does not react with sulfuric acid.The only acid that gold reacts with is aqua regia: a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3.
YES!!! Historically it is known as 'Aqua Regia' (Regal/Royal Water). The ratio of the mixture is HNO3:HCl :: 1:3 On mixing it is a clear fuming acid mixture, but very soon turns yellow orange red. It is named as 'Aqua Regia' because it will dissolve/react with the regal metals, Gold and platinum.
Hydrochloric acid is HCL Sulfuric acid is H2SO4 Mixing hydrochloric and sulfuric acid would just result in the sulfuric acid sapping (dehydrating) the hydrochloric acid of its water, releasing a small amount of hydrogen chloride. However, no chemical reaction is taking place.

No, sulphate salts are very stable and can not be converted into acid.
There is no single "chemical equation for aqua regia". Aqua regia is a mixture of concentrated nitric and sulfuric acids, which is capable of many reactions. The characteristic that gave aqua regia its name is its ability to dissolve gold, but dissolution is usually not considered a chemical reaction
By mixing hydroxide and sulfuric acid

Nothing actually happens. However, if you add concentrated sulphuric acid to fuming nitric acid, you will have created aqua regia which will dissolve gold. Neither acid alone will do this, and it is used as a test for gold. Note. aqua regia is latin for royal water.
When mixing conc. sulfuric acid and water, add acid to water and not vice-versa as that releases lot of energy resulting in injuries.
