Question

what is difference between endothermic and exothermic reaction? give 3 points each. helpful answer will be marked as brainliest.

Answer 1

Endothermic Reactions

The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat. Few examples of endothermic process is photosynthesis, evaporating liquids, melting ice, dry ice, alkanes cracking, thermal decomposition, ammonium chloride in water and much more.

Exothermic Reactions

The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding. Few examples are neutralization, burning a substance, reactions of fuels, deposition of dry ice, respiration, solution of sulfuric acid into water and much more

Answer 2

exothermic reaction
those reaction in which heat is produce
ex.
1.Respiration
2. C+O2 -CO2 + heat
3. burning of magnisium wire in air

endothermic

those reaction in which heat is absorbed.
ex .
CaCo3 +heat - CaO + Co2
all decmposition are endothermic reaction.
