Name two metals which will displace hydrogen from dilute acids, and two metals which will not.

Question 7. Name two metals which will displace hydrogen from dilute acids, and two metals which will not.
Answer: Iron and aluminium will displace hydrogen from dilute acids as they more reactive then hydrogen. Mercury and copper cannot displace hydrogen from dilute acids as they are less reactive than hydrogen.

    Isn't it that copper can also displace hydrogen? Looks like the answer is a bit wrong
