Question

what does one mean by exothermic and endothermic reactions? Give example ​

Answer 1

Answer:

exothermic reaction :- the process in which heat is given out is called an exothermic reaction

ex. NaOH + H2o

NaOH +Heat

Explanation:

endothermic reaction :- the reaction in which heat is absorbed is called an endothermic reaction

ex. KNo 3+H2o + heat

KNO
