Question

Assertion (A): Sodium Hydroxide reacts with zinc to produce hydrogen 1 point
gas Reason (R): Acids react with active metals to produce hydrogen gas

(a) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct
explanation of Assertion (A)

(b) Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct
explanation of Assertion (A)

(c) Assertion (A) is true but Reason (R) is false

d) Assertion (A) is false but Reason (R) is true

(e) Both Assertion (A) and Reason (R) are false​

Answer 1

Answer:

Answer:b). both

Answer:b). both Explanation:

Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct

Both Assertion (A) and Reason (R) are true and Reason (R) is not the correctexplanation of Assertion (A)

Answer 2

(b) Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).

• we know that Sodium hydroxide is a strong base and strong bases react with active metal to produce hydrogen gas,
• Hence, it reacts with zinc to produce H2 gas.
• The reaction is given as follows:

                       Zn (s) + 2NaOH (aq) → Na2ZnO2 (aq)+ H2 (g)

• Acids also react with active metals to produce hydrogen gas.

Thus, both assertion and reason are true, but reason is not the correct explanation of the assertion.
