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

A dog runs 68 meters from one corner of a rectangular park to the opposite corner . If the length of the park is 60 meters , wha

rewona [7]

Answer:

32 meters

Explanation:

You use the formula a^2 + b^2 = c^2.

Plug in the length and hypotenuse.

60^2 + b^2 = 68^2

Simplify and Solve:

3600 + b^2 = 4624

4624 - 3600 = b^2

1024 = b^2

Sqrt 1024 = 32

b = 32

Mutualism- both organisms benefit
Commensalism- one organism benefits while the other neither is harmed or helped
Parasitism- one organism is benefited while the other is harmed

4 P (flea benefits but dog is harmed)
5 M (both get to eat the honey)
6 C (bird gets a place to live without harming or helping the tree)
7 P (lice get a place to live but humans are harmed)
8 M (both are helped)
9 C (flower isn’t harmed or helped but bee is helped)
10 P (the tree is harmed but the mistletoe is benefitted)

Explain how muscle cells, blood cells and small intestine cells work together to keep the body moving.

spayn [35]

Answer:

Cells are considered the fundamental units of life. The cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task. ... At each level of organization—cells, tissues, organs, and organ systems—structure is closely related to function.

Hope this is helpful :)

C5H12 + 8O2 → 5CO2 + 6H2O<br><br> Calculate the energy change for the reaction:

KATRIN_1 [288]

C5H12 (l) + 8O2 (g) ----> 5CO2 (g) + 6H2O (l)
Delta H = -3505.8 kJ/mol

C (s) + O2 (g) -----> CO2 (g)
Delta H = -393.5 kJ/mol

H2 (g) + (1/2)O2 (g) ------> H2O (l)
Delta H = -286 kJ/mol

Possible answers:
a. +35 kJ/mol
b. + 1,073 kJ/mol
c. -4,185 kJ/mol
d. -2,826 kJ/mol
e. -178 kJ/mol
