1.As to the binding energy of different atomic nuclei, it turns out that





A.excepting radioactive elements, the most stable elements have mass numbers of 100 or higher





B.as binding energies increase, the stability of nuclei decreases





C.binding energies are strongest among the light elements with the exception of hydrogen





D.the most stable elements have mass numbers of around 56











2.Regarding types of organic reactions, which statements is false?





A.certain foods containing unsaturated molecules may be hydrogenated to maximize spoilage





B..if an unsaturated compound acquires a halogen---like flourine---the reaction is said to proceed by subsitution





C. unsaturated organic compounds have one or more double or triple bonds





D.if one hydrogen bond in a saturated organic compound is replaced by a bromine atom, we speak of subsitution

1. D.





2. A, because hydrogenating unsaturated molecules should minimize spoilage, not maximize it.
