Base your answer to this question the information below. Cobalt-60 is commonly used as a source of radiation for the prevention of food
spoilage. Bombarding cobalt-59 nuclei with neutrons produces the
nuclide cobalt-60. A food irradiation facility replaces the cobalt-60, a
source of gamma rays, when the radioactivity level falls to 1/8 of its initial
level. The nuclide cesium-137 is also a source of radiation for the
prevention of food spoilage. 28. Identify one emission spontaneously
released by a cobalt-60 nucleus. *

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
