The beakers below depict the aqueous dissociations of weak acids HA (light blue and green) and HB (light blue and yellow); solvent molecules are omitted for clarity. If the HA solution is 0.50 L, the HB solution is 0.25 L, and each particle represents 0.060 mol, find the Ka of each acid.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

i need mutiple choices

a is the correct answer

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
