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⁻

3 to balance the calciums on both sides of the equation, but only if that balances the Cl on both sides of the equation to because you now have 6 Cl and 3Ca
When forming an ion, this sodium atom will lose 1 electron, as it is the easiest way to form a full shell, as opposed to gaining 7 electrons.
Answer: The correct answer is: the water can transfer heat to your arm more quickly than the air.
Explanation: The heat is transferred from the air or water to your arm through convection. The convective heat transfer coefficient of water is higher than the air's, so, even though the temperature of boiling water is lower, the heat will be transferred more efficiently to the other surface, in this case, the hand.
