Question

What does one mean bey exother mic and Endothenic .reachion ?
give Examples​

Answer 1

Answer: Exothermic reaction and endothermic reaction are reaction in which heat is involved.

Explanation: Endothermic reaction are the reactions in which the use of energy is released to form a new chemical reaction.

It requires energy in the form of heat.

Heat energy is absorbed.

For eg. melting of ice, evaporation, photosynthesis-

(CO2+H20+energy gives C6H12O6)

Exothermic reaction where the energy is released or evolved in the form of heat.

It evolves or releases in the form of heat,sound, light or electricity.

It gives or evolves out heat.

For eg. Rusting of iron, explosion, respiation

Answer 2

Answer:

●The type of chemical reactions in which heat or energy is released in the form of light or any other forms are called Exothermic Reaction.

For example:- Carbon+Oxygen=Carbon-dioxide+heat...

●The type of chemical reactions in which heat or energy is absorbed is released in the form of light or other forms are called Endothermic reactions.

For Example:- FeSO4-----》Fe2O3+SO2+SO3
