A metal with shining apperance reacts with hot water and also with dilute HCl and evolving H2 gas. Suggest giving reasons why this metal can't nbe copper.
Answers
The given metal cannot be copper because in reactivity series copper lies below hydrogen and hence it cannot displace hydrogen from HCl to give H₂ gas .
Moreover , copper doesn't react with water due to the fact that each oxygen molecule that is found in water in attached to 2 molecules of hydrogen making it a stable substance . And we already know that copper cannot displace hydrogen . Thus, copper doesn't react with hot / cold water nor with steam and also not with HCl .
Answer:
This is so because copper lies below in the series than hydrogen.
Explanation:
Single displacement reaction can be defined as the reaction in which a more reactive element displace a less reactive element from its chemical reaction. The reactivity of the metal is known as reactivity series.
Hope it helps.
Have a nice day
