Answer:

It's an exothermic reaction

Explanation:

There is release of heat and hence is an exothermic reaction

During a chemical reaction, reactant A combines with reactant B to form product C and the beaker containing reaction mixture becomes hot.

A+ B ----> C+ Q

As the beaker becomes hot . it is the indicator that the heat is released

So it is a Exothermic reaction.

Example :

Calicumoxide reacts with water to form calciumhydroxide and lot of heat

CaO(s) + H2O(l)--> Ca(OH)2 (aq) + Q
