An electrochemical cell was designed using magnesium anode and zinc cathode calculate the EMF of the cell

Chemistry
1 answer:
NeTakaya2 years ago
4 0

When the cell potential is positive then the electrochemical reaction is spontaneous. The Ecell is positive when Zn serves as cathode and Mg serves as anode hence the reaction is spontaneous.

An electrochemical cell is any type of cell in which energy is produced by a spontaneous chemical reaction. Redox reactions that occur in an electrochemical cell produce energy.

An electrochemical cell becomes spontaneous only when Ecell is positive. Ecell is positive when a metal that has a more negative electrode potential serves as the anode.

Since Mg has a more negative electrode potential that Zn, it follows that a cell in which Mg is the anode and Zn is the cathode will have a positive Ecell and the reaction will be spontaneous.

E. Give evidence to support or dispute: "In nature, the chance of finding one isotope
Nadusha1986 [10]

Answer:

This question appears incomplete

Explanation:

However, the chance of finding one isotope of an element is not the same for all elements because some elements/isotopes are more in abundance than some other elements/isotopes; for example the most abundant element on earth is nitrogen-14, hence the chances of finding nitrogen-14 in nature is higher the chances of finding any isotope of Xenon.

Also, while isotopes occur naturally, some do not. Hence, the chances of finding a naturally occurring isotopes (no matter how rare like Xenon-126) is higher than the chances of finding artificial radioisotopes like technetium-95 and promethium-146 (whose chances are zero because they cannot be found naturally occurring).

A sample of fluorine gas occupies 810 milliliters at 270 K and 1.00 atm. What volume does the gas occupy when the pressure is do
sertanlavr [38]

Answer:

The answer to your question is Volume = 600 ml

Explanation:

Data

Volume 1 = 810 ml

Temperature 1 = 270°K

Pressure 1 = 1 atm

Volume 2 = ?

Pressure = 2 atm

Temperature 2 = 400°K

Process

1.- To solve this problem, use the Combine gas law.

               P1V1 / T1 = P2V2 / T2

- Solve for V2

                V2 = P1V1T2 / T1P2

2.- Substitution

                 V2 = (1)(810)(400) / (270)(2)

3.- Simplification

                 V2 = 324000 / 540

4.- Result

                 V2 = 600 ml
