Achemical reaction is carried out in a closed container. the energy absorbed by the chemical reaction is 50 kj. what is the energy liberated from the air or the walls of the container?

a)50 kj
b)75 kj
c)25 kj
d)100 kj

A) 50 kJ.

Explanation:

According to the law of conservation of energy that energy can not be destroyed or created from nothing but it can be converted from one form to another.In a closed system; the amount of heat released by a part of the system is equal to the amount of heat absorbed by other parts of the system.

Q released = Q absorbed.

So, the energy liberated from the air or the walls of the container is 50 kJ.
