Identify metals P, Q, R, S and T.​

Answer 1

Answer:

Explanation:

planation:

ln reactivity series, the order of reactivity of given metals is as follows :

Mg>Al>Zn>Fe>Cu

Thus, rate of evolution of H2 gas in case of Mg is maximum followed by Al, Zn and then Fe. Cu does not react with dil.HCl, so no evolution of H2 gas is observed.
