Answer 2

Explanation:

In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat.A good example of an endothermic reaction is photosynthesis. On the other hand, an exothermic reaction releases energy into the surrounding of the system.An example of an exothermic reaction is the mixture of sodium and chlorine to yield table salt.
