Choose the three items that are characteristic of a strong base.

many OH- ions

few H+ ions

large Kb and small Ka

Explanation:

A strong base has a large concentration of OH-. A typical example of this is NaOH.

Also a strong base usually has a very low concentration of H^+ ions and a very high concentration of OH^- ions.

Lastly, it must have a very high base dissociation constant. Its Kb, the base dissociation constant is a measure of how completely a base dissociates into its component ions in water. The higher the Kb, the stronger the base. A strong base dissociates completely in solution.

your answer would be “dry”

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
