If hydrofluoric acid is a stronger acid than acetic acid, which statement is most likely true? the conjugate acid of hydrofluoric acid is weaker than that of acetic acid. the conjugate acid of hydrofluoric acid is stronger than that of acetic acid. the conjugate base of hydrofluoric acid is weaker than that of acetic acid. the conjugate base of hydrofluoric acid is stronger than that of acetic acid.

Option (c) is the correct answer.

Explanation:

Bronsted-Lowry stated that acids are the species which donate a proton whereas bases are the species which accept a proton.

Also, a strong acid results in the formation of a weak conjugate base and a weak acid results in the formation of a strong conjugate base.

Similarly a strong base results in the formation of a weak conjugate acid and a weak base results in the formation of a strong conjugate base.

The reaction for hydrofluoric acid and acetic acid is as follows.

Thus, hydrofluoric acid being a strong acid gives a weak conjugate base whereas acetic acid being a weak acid gives strong conjugate base .

Hence, the conjugate base of hydrofluoric acid is weaker than that of acetic acid.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
