Calculate the nuclear binding energy of a 32/16 s atom. the measured atomic mass of 32/16 s is 31.972 070 u.

4.993 ×10⁻¹¹ J

Explanation:

The nuclear binding energy is the energy equivalent to the mass defect.

The mass defect is the difference between the mass of a nucleus and the sum of the masses of its nucleons.

Calculate the mass defect

  16 p = 16 × 1.007 28 u =  16.116 48  u

  16 n = 16 × 1.008 67 u =  16.138 72  u

Total mass of nucleons = 32.255 20 u

             - Mass of S-32 = 31.972 070 u

                 Mass defect =  0.283 13   u

Convert the unified atomic mass units to kilograms.

Mass defect

Use Einstein’s equation to convert the mass defect into energy

answer: they produce more slow than unicellular organisms.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
