Question 1

Nuclides with too many neutrons to be in the band of stability are most likely to decay by what mode?

alpha emission
fission
positron production
electron capture
beta emission

Question 2

One of the hopes for solving the world's energy problem is to make use of the fusion reaction:
              H + H → He + n + energy
How much energy is released when one mole of deuterium is fused with one mole of tritium according to the above reaction? The masses of the atoms and the neutrons are:
              H = 2.0140 amu          H = 3.01605 amu
              He = 4.002603 amu     n = 1.008665 amu
The speed of light is 2.9979 × 108 m/s

5.63 × 108 J
56.3 J
1.69 × 1012 J
7.84 × 1044 J
8.44 × 1011 J
