Fill in the blank.
weak bases react with to form the hydroxide ion and the conjugate of the base. concentration in solution does not affect whether an acid or a base is or weak.
the strength of an acid or a base is determined by the of the substance in solution.
the acid dissociation constant, is a quantitative measure of acid strength. a strong acid has a much ka than a weak acid. the ka of an acid is determined from measured values.
hydrochloric acid and sulfuric acid are ionized in solution and are acids. ethanoic acid, which is only about 1 percent ionized, is a acid. magnesium hydroxide and calcium hydroxide are strong

Answer :The corrected answer is given below;

Weak bases react with water to form the hydroxide ion and the conjugate acid of the base. Concentration in solution does not affect whether an acid or a base is strong or weak.

The strength of an acid or a base is determined by the dissociation constant of the substance in solution.

The acid dissociation constant, Ka, is a quantitative measure of acid strength. A strong acid has a much higher Ka than a weak acid. The Ka of an acid is determined from measured titration values.

Hydrochloric acid and sulfuric acid are completely ionized in solution and are strong acids. Ethanoic acid, which is only about 1 percent ionized, is a weak acid. Magnesium hydroxide and calcium hydroxide are strong base.

Area of the rectangle = ( x²+12x+27)unit²

Step-by-step explanation: Length = x+3  Breadth = x+9

∴ Area of Rectangle = L×B

(x+3)(x+9) = x²+9x+3x+27 = (x²+12x+27) unit²
