Answer 1

Answer:

Heya✌️☺️♥️

Explanation:

✏️The element "X" is 'Gold.(Like copper, gold is a good conductor of heat and electricity )

• ✏️Gold has a very high boiling and melting point.It's a soft, ductile metal. 

• ✏️Gold is a noble metal.it will not tarnish and also highly reflective,which is very heavy and dense.

✏️Gold metal dissolves in aqua regia, a mixture of hydrochloric acid, HCl, and concentrated nitric acid, HNO3, in a 3:1 ratio. The name aqua regia was coined by alchemists because of its ability to dissolve gold - the "king of metals".

✒️ Additional information:-

✏️Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold. ... Gold does react with halogens. It will, for example, react very slowly with chlorine gas at room temperature to form gold chloride, AuCl3.
