Question
A nuclear reaction is represented by the equation:$^{2}_{1}\text{H}+{^{2}_{1}\text{H}}\rightarrow{^{3}_{2}\text{He}}+\text{xc}+\text{E}$
  1. Name the process represented by this equation and describe what happens during this reaction.
  2. Identify the particle c and the number x of such particles produced in the reaction.
  3. What does E represent?
  4. State two conditions under which such a reaction takes place.
  5. What type of nuclear bomb is based on similar reactions?
✓

Answer

  1. Nuclear fusion; two smaller nuclei combine to form a bigger nucleus with the release of energy, brought about under the conditions of high temperature and pressure.
  2. Particle c is neutron; x= 1
  3. Energy liberated.
  4. Millions of degree of temperature and millions of pascals of pressure.
  5. Hydrogen bomb.
