Explanation:
The given reaction at cathode will be as follows.
At cathode: , = -0.761 V
At anode: , = 0.761
Therefore, net reaction equation will be as follows.
Initial: 0.129 - - 0.427
Change: -0.047 - - -0.047
Equilibrium: (0.129 - 0.047) (0.427 - 0.047)
= 0.082 = 0.38
As for the given reaction is zero.
Hence, equation for calculating new cell potential will be as follows.
E_{cell} =
=
= 0.019
Thus, we can conclude that the cell potential of the given cell is 0.019.
Based on the information given in the question, the cholesterol has:
a mass of 0.406 g
&
moles of 0.00105 mol
Now, Molecular Mass = Mass ÷ Moles
= 0.406g ÷ 0.00105mol
= 386.6667 g/mol
≈ 386.67 g/mol
Answer:
the chemical energy flows into the engines and the engines starts to work.When the engines work mechanical energy is generated as mechanical energy is obtained when there is movement
D.The sun does not rotate
The centers for disease control and prevention (CDC) develops recommendations for water fluoridation along with technical requirements for each major compound used.
<h3>What is meant by water fluoridation?</h3>
Almost all water contains some fluoride, but usually not enough to prevent tooth decay. Fluoride can also be added to drinking water supplies as a public health measure for reducing cavities. Water fluoridation is the process of adding fluoride to the water supply so the level reaches approximately 0.7 ppm or 0.7 milligrams of fluoride per liter of water, this is the optimal level for preventing tooth decay.
