Question

What are endothermic and exothermic? chemical reaction give one example each to support your answer ​

Answer 1

Answer:

endothermic

endothermic is a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature

chemical reaction - NH4Cl (s) + H2O (l) ⟶ NH4Cl (aq) – Heat

exothermic

he term exothermic process describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity, or sound

chemical reaction - CH4 + O2 → CO2 + H2O + Heat

Answer 2

Answer:

Endothermic reaction:

It is a type of reaction which takes place by absorbing heat.

Ex : Photosynthesis reaction

CO2 + H2O ------- C6H12O6 + O2

Exothermic reaction:

It is a type of reaction which take place by releasing heat.

Ex : Respiration reaction

C6H12O6 + O2 ------ CO2 + H2O
