Question

17. Assertion (A): Copper can react with steam and liberates H, gas Reason (R) : Sodium reacts with water and liberates H, gas a) Both A and R are true and R is the correct explanation of A b) Both A and R are true and 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 1

Answer:

Assertion is true but Reason is false

Answer 2

The answer is d) A is false but R is true​

Assertion is- Copper can react with steam and liberates hydrogen gas. (False)

Copper does not react with water, even if water is converted into steam. Metals like lead, silver, and gold do not react with water like copper.

Reason is- Sodium reacts with water and liberates hydrogen gas. (True)

Sodium reacts even with cold water. Sodium is highly reactive and the reaction of sodium with water liberates enormous energy. The evolved energy during this exothermic reaction is so high that the hydrogen immediately catches fire.

Thus, assertion is false but the reason is true.
