Calculate the mass defect and the nuclear binding energy of nitrogen-14. the mass of a proton is 1.00728 amu, and the mass of a neutron is 1.00866 amu. the mass of a nitrogen-14 atom is 14.00307 amu.

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
