the system is usually defined as the chemical reaction and the boundary is the container in which the reaction is run in the course of the reaction heat is either given off or absorbed by the system furthermore the system either does work on it surroundings or has work done on it by its surroundings
While Nuclear reaction is not depended on chemical combinations, chemical reaction is largely depended on chemical combinations. When mass changes can be detected in a nuclear reaction, in the chemical reactions, the mass of the reactants are equal to mass of the products. Summary 1.
