Breaking of bonds is endothermic, formation of bonds is exothermic. Combustion is exothermic
Absorbtion of heat, dissolution of gases in water,breaking of bonds are endothermic reaction
examples thermal decomposition of Caco3 , NH4cl.
Also Evaporation and photosynthesis etc
Myschool in the video you chose option D and here you chose option C, which is the correct answer?
decomposition of hydrogen peroxide is exothermic. ref new school chemistry 2018 edition pg 376
