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)

antimony(III) sulfide is reacted with excess iron. if 175.6 grams of pure antimony is produced what mass of antimony sulfide was
Ad libitum [116K]

Answer: -

The chemical formula of Antimony(III) sulfide = Sb₂S₃

Mass of Sb produced = 175.6 g

Molar mass of Sb = 121.76 g /mol

Number of moles of Sb = 175.6g / (121.76 g/mol)

= 1.44 mol

The balanced chemical equation for this reaction is

Sb₂S₃ + 3 Fe → 2 Sb + 3 FeS

From the chemical equation we see

2 mol of Sb is produced from 1 mol of Sb₂S₃

1.44 mol of Sb is produced from \frac{1 mol Sb2S3 x 1.44 mol Sb}{2 mol of Sb}

= 0.72 mol of Sb₂S₃

Molar mass of Sb₂S₃ = 2 x 121.76 + 32.06 x 3

= 339.7 g / mol

Mass of Sb₂S₃ = 0.72 mol x 339.7 g/ mol

= 244.58 g

= 244.6 g rounded off to 4 significant figures.

A galvanic cell consists of one half-cell that contains Ag(s) and Ag+(aq), and one half-cell that contains Cu(s) and Cu2+(aq). W
Agata [3.3K]

Answer : The 'Ag' is produced at the cathode electrode and 'Cu' is produced at anode electrode under standard conditions.

Explanation :

Galvanic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the voltaic cell or electrochemical cell.

In the galvanic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.

We are taking the value of standard reduction potential form the standard table.

E^0_{[Ag^{+}/Ag]}=+0.80V

E^0_{[Cu^{2+}/Cu]}=+0.34V

In this cell, the component that has lower standard reduction potential gets oxidized and that is added to the anode electrode. The second forms the cathode electrode.

The balanced two-half reactions will be,

Oxidation half reaction (Anode) : Cu(s)\rightarrow Cu^{2+}(aq)+2e^-

Reduction half reaction (Cathode) : Ag^{+}(aq)+e^-\rightarrow Ag(s)

Thus the overall reaction will be,

Cu(s)+2Ag^{+}(aq)\rightarrow Cu^{2+}(aq)+2Ag(s)

From this we conclude that, 'Ag' is produced at the cathode electrode and 'Cu' is produced at anode electrode under standard conditions.

Hence, the 'Ag' is produced at the cathode electrode and 'Cu' is produced at anode electrode under standard conditions.

What is the symbol of an ion with 16 protons, 18 neutrons, and 18 electrons? what is the symbol for an ion that has 16 pro-tons,
Goshia [24]

When we go to periodic table, Sulfur is an element that has 16 protons and 16 electrons.

when there is 18 electrons, with number of two electrons more than protons. This makes it an ion and the ion has a -2 charge.

So when there is16 protons, 18 neutrons, and 18 electrons the symbol is S⁻².

The neutrons have no charge but they add only mass to the elements. So when there is 16 neutrons, it doesn't change the symbol of ion.

Galvanized nails are iron nails that have been plated with zinc to prevent rusting. The relevant reaction is
fomenos

Answer:

1.18 × 10⁷ c

Iron is the anode and zinc is the cathode.

Explanation:

Let's consider the reduction of Zn²⁺.

Zn²⁺(aq) + 2 e⁻ ⇒ Zn(s)

<em>How many coulombs of charge are needed to produce 61.2 mol of solid zinc?</em>

<em />

We can establish the following relations:

  • When 2 moles of electrons circulate, 1 mol of Zn is produced.
  • 1 mole of electrons have a charge of 96468 c (Faraday's constant).

Then, for 61.2 mol of Zn:

61.2molZn.\frac{2mole^{-} }{1molZn} .\frac{96468c}{1mole^{-}} =1.18 \times 10^{7} c

<em>Identify the anode and cathode when plating an iron nail with zinc.</em>

The anode is where the oxidation takes place and the cathode is where the reduction takes place.

Anode (oxidation): Fe(s) ⇒ Fe²⁺(aq) + 2 e⁻

Cathode (reduction): Zn²⁺(aq) + 2 e⁻ ⇒ Zn(s)
