Question

Assertion: Reactivity Series is an arrangement of element based on
their reactivity.
Reason: Reactivity Series is used to separate elements based on their
reactivity.
Assertion reasoning question class 10 metals and non metals CBSE

Answer 1

Answer:

Both are correct but Reason isnt the correct explanation of the assertion.

Explanation:

Look dude,

By reading itself you can understand that clearly the reason isnt the correct explanation, its pretty much self explanatory. Reactivity Series is used to separate elements based on their  reactivity isnt the right reason.

Btw do you study in DPS Sharjah?

Answer 2

Answer:

Both assertion and reason are correct.

Explanation:

Reactivity series : Reactivity series is the arrangement of the metals based on their reactivity. A more reactive metal is placed above the less reactive metal. In a chemical reaction, a more reactive metal replaces a less reactive metal. For example: Sodium is placed above calcium in the reactivity series. In a reaction involving sodium and calcium , sodium being more reactive replaces calcium.

Elements placed below hydrogen in reactivity series are copper, mercury, silver, gold.
