Question

explain The exothermic and endothermic reactions with example
​

Answer 1

Answer:

An example of an exothermic reaction is the chemical reaction between sodium and chlorine, which results in the formation of sodium chloride (also known as common salt). The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat.

Answer 2

Answer:

Endothermic Reaction:- Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

Eg:-                                                                                                                                         1. Melting ice cubes.

2. Melting solid salts.

3. Evaporating liquid water.

4. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.

5. Making an anhydrous salt from a hydrate.

Exothermic Reaction:- An 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.

Eg:-

1. Making of an ice cube. Making ice cube is a process of liquid changing its state to solid.  

2. Snow formation in clouds.  

3. Burning of a candle.  

4. Rusting of iron.  

5. Burning of sugar.

Thank you:)

I hope it will help understand that what is endothermic and exothermic reactions.
