What would be the freezing point of a solution that has a molality of 1.324 m which was prepared by dissolving biphenyl (C12H10) into naphthalene

Answers

The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.

A solution is prepared by dissolving biphenyl into naphthalene. We can calculate the freezing point depression (ΔT) for naphthalene using the following expression.

[tex]\Delta T = i \times Kf \times m = 1 \times 6.90 \°C/m \times 1.324m = 9.14 \°C[/tex]

where,

i: van 't Hoff factor (1 for non-electrolytes)Kf: cryoscopic constantm: molality

The normal freezing point of naphthalene is 80.26 °C. The freezing point of the solution is:

[tex]T = 80.26 \° C - 9.14 \° C = 71.12 \° C[/tex]

The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.

What is the science behind procrastination? Most descriptive and accurate answer will receive brainliest.

Answers

Answer:

Explanation:

Procrastination is a plague to which we are all susceptible. Essentially, procrastination is the avoidance of work or necessary tasks by focusing on more satisfying activities. It’s easy to chalk procrastination up to a lack of self-motivation, lazy habits or incompetence. But in reality, procrastination is chemical; there’s a science to why we prefer relaxing activities to the required.

Procrastination boils down to a battle between the limbic system and the prefrontal cortex. The limbic system is a set of brain structures containing the pleasure center, while the prefrontal cortex controls planning and decision making. The prefrontal cortex is less developed and thus weaker, so often times the limbic system wins out, leading to procrastination.

what is the molarity of an acetic acid solution if 25.0mL of the Hc2H3O2 solution is titrated with 29.7 mL of a 0.205 M KOH solution

Answers

The molarity of the acetic acid, HC₂H₃O₂ solution is 0.244 M

We'll begin by writing the balanced equation for the reaction

HC₂H₃O₂ + KOH —> KC₂H₃O₂ + H₂O

From the balanced equation above,

The mole ratio of the acid, HC₂H₃O₂ (nA) = 1

The mole ratio of the base, KOH (nB) = 1

From the question given above, the following data were obtained:

Volume of the acid, HC₂H₃O₂ (Va) = 25 mL

Volume of the base, KOH (Vb) = 29.7 mL

Molarity of the base, KOH (Mb) = 0.205 M

Molarity of the acid, HC₂H₃O₂ (Ma) =?

MaVa / MbVb = nA/nB

(Ma × 25) / (0.205 × 29.7) = 1

(Ma × 25) / 6.0885 = 1

Cross multiply

Ma × 25 = 6.0885

Divide both side by 25

Ma = 6.0885 / 25

Ma = 0.244 M

Therefore, the molarity of the acetic acid, HC₂H₃O₂ solution is 0.244 M
