Explanation:

Chemical reactions in which energy is liberated in the form of heat are referred to as exothermic reactions.

Therefore, when a salt is added to water and beaker becomes hot then it shows that reaction is exothermic in nature.

The substance X could be quick lime or calcium oxide. The reaction will be as follows.

     CaO + H_{2}O \rightarrow Ca(OH)_{2}
