Solution

## Reactivity seriesThe arrangement of metals in descending order of their reactivities is referred to as the "metal reactivity series," sometimes known as the "activity series."To determine if a metal can displace another in a single displacement reaction, one can use the information offered by the reactivity series. It can also be used to find out reactivity of metals toward water and acids.Metals that do not react with dilute hydrochloric acidMetals that do not react with dilute Hydrochloric acid$\left(\mathrm{HCl}\right)$ are copper, silver, gold, and mercury.It is because they come after hydrogen in the activity series.So, these metals can't replace hydrogen from hydrochloric acid.
