Substance A is an acid.
Substance B is a group of hydronium ions.
Explanation:
From the description above, we can deduce that substance A is an acid whereas substance B is a group of hydroxonium ions.
An acid can be defined as a substance that produces hydrogen ions in solution.
Acids interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution.
The hydroxonium ions results from the chemical bonding between oxygen of water molecules and protons released by the ionization of the acid:
HCl + H₂O → H₃O⁺ + Cl⁻

Answer:
Boron
Explanation:
The group III A is also known in the periodic table as group 13. The members of the group begin to appear in the second period.
At the beginning of this group III A is boron. Boron is a member of group III A as well as a member or period 2.
Boron is a metalloid and has only three valence electrons as other group III A elements.
