A student has a sample of an insoluble solid and a liquid. The task is to separate the mixture into its pure components. What qu

estion is best asked in the design of the experiment to determine how to separate the components?
A) Is the solid/liquid mixture toxic in its combined form?

B) Is the solid large enough to be caught by the pores of a filter?

C) Is the melting temperature of the solid lower than that of the liquid?

D) Can the solid be crushed into smaller particles to allow for distillation?

Answer:

<em><u></u></em>

  • <em><u>B) Is the solid large enough to be caught by the pores of a filter? </u></em>

Explanation:

An <em>insoluble solid</em> and a <em>liquid</em> form an heterogeneous mixture, meaning the liquid and the solid could be <em>separated</em> by physical media.

If the size of the solid particles are large enough it could be separated from the liquid by filtration.

Since, the task is to separate the mixture into its pure components, the best and first step is to determine whether the solid particles have the size that permit to retain them in the available fliter, which is described by<em> </em>the option <em>B): is the solid large enough to be caught by the pores of a filter? </em>

As for the other options:

<em>A) Is the solid/liquid mixture toxic in its combined form?</em>

  • a mixture is not more toxic than its pure components, because they are a physical combination and not a chemical one.

<em>C) Is the melting temperature of the solid lower than that of the liquid?</em>

  • you do not want to melt the solid, because that would make the separation more difficult.

<em>D) Can the solid be crushed into smaller particles to allow for distillation? </em>

  • crushing the solid will not make it soluble and will not change the boiling point of the solution, thus this is not a step to separate the mixture into its components.

zaharov [31]

Answer:

P_{He}^|=288.85torr

Explanation:

Given data

P_{He}=750 torr\\V_{He}=285mL\\P_{Ar}=732 torr\\V_{Ar}=455 mL

Required

Partial pressure of helium

Solution

First calculate the total volume of gas mixture once the stopcock is opened

So

V_{total}=V_{He}+V_{Ar}\\V_{total}=285mL+455mL\\V_{total}=740mL

As temperature remains constant,by Boyle's Law we calculate the partial pressure of the helium gas

So

P_{He}V_{He}=P_{He}^|V_{total}\\P_{He}^|=\frac{P_{He}V_{He}}{V_{total}}\\P_{He}^|=\frac{750torr*285mL}{740mL}\\  P_{He}^|=288.85torr

Answer:

The doorbell transforms electrical energy into sound.

Explanation:

The doorbell MAY turn electrical energy into motion of a striker which then impacts a resonator creating sound. However all door bells do not have solenoids. Some are electronic playing recordings when activated.

All doorbells do produce sound, though.
