C and A because the product of a matter will always be the same and just google A.
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
Answer is: gamma emission or gamma decay.
<span>During gamma emission the nucleus emits radiation without changing its composition, if for example have nucleus with six protons and six neutrons (carbon atom) and after gamma decay there is nucleus with six protons and six neutrons.
</span>Gamma rays are the
electromagnetic waves with the shortest wavelengths (1 pm), highest
frequencies (300 EHz) and highest energy (1,24 MeV).
