Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has

Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell.

<h3>What is an electrolytic cell?</h3>

An electrolytic cell that uses electrical energy to enable a non-spontaneous redox reaction is known as an electrolytic cell.

Certain chemicals can be electrolyzed using electrolytic cells, which are electrochemical cells.

For example, water can be electrolyzed to create gaseous oxygen and gaseous hydrogen with the use of an electrolytic cell.

The following are the three essential parts of electrolytic cells:

Cathode (which is negatively charged for electrolytic cells)

Anode (which is positively charged for electrolytic cells)

Electrolyte

The reactions for each half cell is given by

Au^{3+}(aq) + 3e^- \rightleftharpoons Au(s) ; E° = 1.50 V

Cr^{3+}(aq) + 3e^- \rightleftharpoons Cr(s) ; E° = –0.74 V

Co^{2+}(aq) + 2e^- \rightleftharpoons Co(s) ; E° = –0.28 V

Zn^{2+}(aq) + 2e^- \rightleftharpoons Zn(s) ; E° = –0.76 V

When the Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell, the a difference in the voltages is produced

E^o_{series} = E^o_{Au/Cr} - E^o_{Co/Zn}  = 2.24 V – 0.48 V = 1.76 V

Answer:

Option (2)

Explanation:

Since the amount of each sample is the same, we are looking for the metal with the greatest density, which is copper.

Why does nuclear charge increase as you go left to right across a period
MariettaO [177]

 The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.

Hydrogen gas has a density of 0.090 g/L, and at normal pressure and -1.72 C one mole of it takes up 22.4 L. How would you calcul
BlackZzzverrR [31]

Answer:

n= \frac{m}{ \rho }* \frac{1 mol}{22.4 L}

Explanation:

Assuming that all caculations are at normal pressure and -1.72°C :

n= \frac{m}{ \rho }* \frac{1 mol}{22.4 L}

Where

n is the number of moles of hydrogen

n is the mass of hydrogen

\rho is the density of hydrogen
