Respuesta :

Final answer:

Copper is the most ductile metal, Mercury is the least dense element, Gold will not liberate hydrogen gas, Gold is likely to be found in the free metal form, and a converter in steel production removes impurities.


Explanation:

Copper is the most ductile metal among the options provided. Ductility refers to the ability of a material to be drawn into thin wires without breaking.

Regarding density, Mercury is the least dense element from the list. Density is a measure of how much mass is contained in a given volume.

Copper is the metal that will not liberate hydrogen gas when treated with dilute hydrochloric acid. This is due to its position in the reactivity series.

In nature, Gold is most likely to be found as the free metal. Gold is often found in pure metallic form in the Earth's crust.

The purpose of a converter in steel production is to help in the removal of impurities like carbon, silicon, and phosphorus from the iron to produce high-quality steel.
