Answer 1

Answer:

write a short note on exothermic reaction and endothermic reaction. give a example

Answer 2

Answer:

Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. A good example of an endothermic reaction is photosynthesis. Combustion is an example of an exothermic reaction. ... In any given reaction, heat is both absorbed and released.

Explanation:

exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an exothermic reaction, change in enthalpy ( ΔH) will be negative.
