Answer: Option (a) is the correct answer.

Explanation:

A strong acid is an acid which completely dissociates into its ions in a solution.

For example, HCl is a strong acid and it dissociates as follows.

$HCl \rightleftharpoons H^{+} + Cl^{-}$

Whereas a weak acid dissociates slightly into a solution.

Thus, we can conclude that it is true of a strong acid that it ionizes close to 100 percent in water.

4. a compound called pyrene has the empirical formula c8h5. when 4.04 g of pyrene is dissolved in 10.00 g of benzene, the boilin

e-lub [12.9K]

The molecular mass of pyrene is 204.4 g/mol.

From;

ΔT = Kb m i

Where;

ΔT = boiling point elevation
Kb = boiling point constant
m = molality
i = Van't Hoff factor

Since the compound is molecular; i = 1

The number of moles of pyrene = 4.04 g/MM

Where; MM = molar mass of pyrene

molality = number of moles of pyrene/mass of solvent in Kg

The mass of solvent = 10 g or 0.01 Kg

molality = 4.04 g/MM/0.01

ΔT = Boiling point of solution - Boiling point of pure solvent

ΔT = 85.1°C - 80.1°C

ΔT = 5°C

5 = 2.53 × 4.04 g/MM/0.01 × 1

5 = 10.22 × 1/0.01 MM

0.05MM = 10.22

MM= 10.22/0.05

MM= 204.4 g/mol

Which carboxylic acid can be combined with an alcohol to form the ester shown below?

Anna11 [10]

Answer:

CH₃CH₂CH₂COOH.

Explanation:

To know which option is correct, let us hydrolysed the given ester. This is illustrated in the attached photo.

Hydrolysis of ester involves breaking the ester bond by a water molecule to produce the corresponding alcohol and carboxylic acid.

From the reaction given in the attached photo, we can see that the carboxylic acid needed to produce the desired ester is butanoic acid, CH₃CH₂CH₂COOH.
