Question

Assertion A: A beaker with 20 ml water on adding a few drops of concentrated H₂SO₄ to it slowly, with constant stirring become hot. Reason R: The heat evolved when acid reacts with water. * 1 point Both A and R are true and R is the correct explanation of A Both A and R are true and R is not the correct explanation of A A is true but R is false A is False but R is true help me
​

Answer 1

both A and R are correct and R is the correct explanation of A

Answer 2

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

Explanation:

1. When a few concentrated drops of H₂SO₄ is added to a beaker with 20 ml of water, an exothermic reaction occurs.
2. An exothermic reaction is a reaction in which energy is released in the form of heat to the surrounding.
3. When sulfuric acid and water react, heat is evolved along with the formation products.
4. This evolved heat raises the temperature of the solution and the beaker becomes 'hot'.
