Answer : An ionic bond is formed when <u>one atom transfers an electron to another atom.</u>
Ionic bond is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal).
Ionic bonds form when one atom gives up one or more electrons to another atom. It is the complete transfer of valence electron(s) between oppositely charged atoms
For example NaCl (sodium chloride ) is an ionic bond, in which valence electron from Na gets completely transferred to the valence shell of Cl and ionic bond is formed between opposite ions that is Na (positive) and Cl (negative).
Note : Ionic bond is formed between metal (electropositive element) and non-metal(electronegative element).

2.64 x 10⁻⁵ M.
Answer:
gaseous state
Explanation:
may be because it is result of endothermic process (evaporation
Magnesium hydroxide Mg(OH)₂ is a weak base.
Explanation:
Sulfuric acid H₂SO₄ and hydrochloric acid HCl are, both of them, very strong acids.
Sodium hydroxide NaOH and potassium hydroxide KOH are hydroxides of metals from the first group in the periodic table so thy are strong bases.
As you go to the second group in the periodic table, the hydroxides will not dissociate as much as the hydroxides from the first group in the periodic table , so they will be weak bases. This is the case of magnesium hydroxide Mg(OH)₂.
