Question
Science Question on Metals and Non-Metals
Assertion (A): Different metals have different reactivities with water and dilute acids.
Reason (R): Extraction of a metal from its ore depends on its position in the reactivity series.
A
Both (A) and (R) are true and (R) is the correct explanation of (A).
B
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
C
(A) is true, but (R) is false.
D
(A) is false, but (R) is true.
Answer
Both (A) and (R) are true and (R) is the correct explanation of (A).
Explanation
Solution
The reactivity of metals varies, affecting their reactions with water and acids. The method of extraction (e.g., electrolysis for highly reactive metals, reduction for less reactive ones) depends on their reactivity series position.
