Question

Assertion (A): Reaction of Quicklime with water is an exothermic reaction. 

Reason (R): Quicklime reacts vigorously with water releasing a large amount of heat.

पर्याय

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation:

Slaked lime is produced with the evolution of a great deal of heat when quicklime (calcium oxide) is treated with water. This reaction is therefore exothermic in nature.
