Question

which of these metals cannot displace hydrogen from a dilute acid? a. brass b.stainless steel c.duralium d.bronze​

Answer 1

Explanation:

ANSWER

In the reactivity series, the metals that come above hydrogen are more reactive than hydrogen and hence they have the ability to displace hydrogen. For example, Sodium(Na), Iron(Fe), Zinc(Zn).

On the other hand, the metals that come below hydrogen in the reactivity series are less reactive than hydrogen and hence they cannot displace hydrogen. For eg, Copper(Cu), Mercury(Hg), Silver(Ag), Gold(Au).

Thus, the correct answer is option (B).
