Write the cell notation for the voltaic cell that incorporates each of the following redox reactions:(a) Al(s) + Cr³⁺(aq) → Al³⁺

Sladkaya [172]

The cell notation for the given voltaic cell is as follows

Al(s) | Al³⁺(aq) || Cr³⁺ (aq) | Cr(s)

<h3>What is a voltaic cell?</h3>

The device in which electrons are transferred through an external source is known as a voltaic cell.

The electron flow of a Voltaic cell allows redox reactions to produce energy in the form of electricity.

It converts the energy of spontaneous redox reaction into electrical energy

An anode, a cathode, and a salt bridge are all parts of a voltaic cell's setup. The salt bridge serves to neutralize the system.

To write the cell notation, identify the oxidation and reduction reactions.

At the anode, oxidation takes place

$Al(s) \longrightarrow Al^{3+} (aq) + 3e^-$

At the cathode, reduction takes place

$Cr^{3+} (aq) + 3e^- \longrightarrow Cr(s)$

While writing cell notation, the anode is written on the left, and the cathode is written on the right

A single vertical line differentiates between the phases and a double vertical line represents the salt bridge.

Now, write the cell notation of the given Voltaic cell

Al(s) | Al³⁺(aq) || Cr³⁺ (aq) | Cr(s)

What is the mole fraction of each component if 3.9 g of benzene (C6H6) is dissolved in 4.6 g of toluene (C7H8)

Savatey [412]

Answer:

Step 1 of 6

(a)

The mass of benzene is , so calculate the moles of benzene as follows:

The mass of toluene is, so calculate the moles of toluene as follows:

Now, calculate the mole fraction as follows:

Therefore, the mole fraction of benzene and toluene is and respectively.

Step 2 of 6

(b)

The formula to calculate the partial pressure is as follows:

Here, is the partial pressure of benzene, is the vapour pressure of pure benzene and is the mole fraction of benzene.

Vapour pressure of pure benzene at is.

Substitute the values in the equation as follows:

Therefore, the partial pressure is .

Step 3 of 6

(c)

Vapor pressure of the solution at 1 atm is .

When the total pressure of the vapour pressure of the mixture is at a temperature, then, the solution boils. It corresponds to the boiling point of the solution.

Calculate the total pressure of the solution at as follows:

Since, the total pressure is less than the atmospheric pressure, the solution will not boil at .

Calculate the total pressure of the solution at as follows:

Since, the total pressure is greater than the atmospheric pressure, the solution will boil at .

Therefore, the boiling point of the solution is .

Step 4 of 6

(d)

Mole fraction of benzene at is calculated as follows:

Mole fraction of toluene at is calculated as follows:

Therefore, the mole fractions of benzene and toluene are and respectively.

Step 5 of 6

(e)

Vapor pressure of benzene at is .

Partial pressure of benzene is calculated as follows:

Vapor pressure of toluene at is .

Partial pressure of toluene is calculated as follows:

Step 6 of 6

Weight composition of the vapour that is in equilibrium with the solution is calculated as follows:
