15. The equation E=mc is one of the lasting symbols of science and nuclear chemistry in general, i. Explain what each term in this equation means and what energy is being calculated. What are the derived units for E? ii. Cempare a nuclear reaction, such as uraniums alpha particle emission, with a nonnuclear reaction, a such as the reaction of sodium with chlorine. What's the fundamental difference between these two types of reactions?
