Answer 2

Gold is one of the least reactive metals (if u chk the reactivity series) so it does not react with HCL

Answer 3

So for this I would use a standard reduction potential chart. Keep in mind for Au you will need to reverse the reaction making it a -1.50 adding this to H+ which is 0.00 will give you -1.50V, being that this is a negative number the reaction does not proceed in this direction but remains a solid (+1.50) which is more favorable.

^quantitative answers are good.
