Question

A chemical 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?
A. 100 kJ

B. 50 kJ

C. 25 kJ

D. 75kJ

Answer 1

Answer:

Option A

Explanation:

The total heat absorbed during the chemical reaction is the total heat released by the surrounding.

Net change of heat is equal to zero

Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj

Thus, option A is correct
