Achemical reaction is carried out in a closed container. the energy absorbed by the chemical reaction is 100 kj. what is the energy liberated from the air or the walls of the container?

The correct answer is 100 kJ

In the definition of the law of conservation of energy, it says that energy cannot be created or destroyed, but can be changed from one form into another. When a chemical reaction absorbs a certain amount of heat, the surroundings must lose the same amount of heat as well.
