If you're asking about vapor its a solid
Answer:
mass
Explanation:
The total mass is located at the bottom, right underneath the symbol of the element. The mass is the sum of both the protons and neutrons for both are equivalent in mass whereas the electrons have almost no mass at all.
Answer is: HCl (hydrochloric acid).
Hydrochloric acid is strong acid and in water dissociates:
HCl(aq) → H⁺(aq) + Cl⁻(aq).
Because acid gives a lot of hydrogen cations (H⁺), pH (pH = -log[H⁺]) is lower than seven (acidic solution).
Ammonia (NH₃) and barium hydroxide (Ba(OH)₂) are base and their pH is higher that seven. Sodium fluoride (NaF) is neutral salt.
