What is a reactivity series?
Which one of these metals could be platinum?
If a reactivity series of the above metals is formed, which metal will
be at the top of the series?
State what happens in a displacement reaction, on the basis of your
understanding of reactivity series.
(d)​

Answer 1

Explanation:

ANSWER

The series which arranges metals in the decreasing order of reactivity is known as the reactivity series. Thus, the least reactive metal is placed at the bottom while the most reactive metal is placed at the top of the series.

so refer it for further information

C. will be the platinum

Displacement Reaction. A more reactive metal displaces a less reactive metal from its salt solution. When a more reactive metal is placed in the salt solution of a less reactive metal,then the more reactive metal displaces the less reactive metal from its salt solution

Answer 2

Answer:

In chemistry, a reactivity series is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.
