Question

We know law of conservation of mass is invalid in nuclear reactions but the total mass energy sum remains constant so here total mass energy remains constant before and after reaction or not ? I mean the total mass and energy remain conserved before and after reaction or not ???

Answer 1

✔The total mass and energy is not conserved as most of the energy is lost in the form of heat. Nuclear reaction involves the formula:
⭐E=mc^2.⭐
