HCl is a strong acid and HA as stated in the statement is a weak acid.
So, in the beaker which contains HCl will have:
In the beaker with HA will have:
<span>Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.</span>
