Consider a generic redox reaction?Consider a generic redox reaction X(s) + Y^+(aq) <----> X^+(aq) + Y(s) then suppose that the coefficients in the redox reaction are doubled. How will the following quantities be affected for a voltaic cell under nonstandard conditions? 1.Doubled 2. Halved 3. Squared 4. No Change The options are InQ, E^o, E, n, Q

Answers

The Nernst equation allows us to predict the cell potential for voltaic cells under conditions other than the standard conditions of 1M, 1 atm, 25°C. The effects of different temperatures and concentrations may be tracked in terms of the Gibbs energy change ΔG. This free energy change depends upon the temperature & concentrations according to ΔG = ΔG° + RTInQ where ΔG° is the free energy change under conditions and Q is the thermodynamic reaction quotient. The free energy change is related to the cell potential Ecell by ΔG= nFEcell

so for non-standard conditions
-nFEcell = -nFE°cell + RT InQ

or

Ecell = E°cell - RT/nF (InQ)

which is called Nernst equation.

Answer:

n and lnQ - doubled

Q - Squared

E, Edegree - No change

What is the total number of electrons in the valence shell of an atom of aluminum in the ground state?(1) 8 (3) 3
(2) 2 (4) 10

Answers

The answer is (3) 3. The outer shell of an atom is called valence shell. And the ground state is the lowest energy state of an atom. Aluminum has a electron distribution of 2, 8, 3. So the outer shell has 3 electrons.

Answer:

C. 3

Explanation:

If you look at aluminum (Al) in the Periodic Table of the Elements, you will see that its electron configuration is 2-8-3. The last number indicates the valence shell, which contains three electrons.

The relationship between the "absolute temperature" on the Kelvin scale and the Celsius temperature is given bv: T(K) = t(°C) + 273.15 t(°C) = T(K) + 273.15 T(K) = 5/8[4°C)] - 32 D) T(K) = 8/5[t(°C)] + 32

Answers

The correct formula for converting Celsius to Kelvin is T(K) = t(°C) + 273.15 and the reverse is t(°C) = T(K) - 273.15. The Kelvin scale, unlike Celsius and Fahrenheit scales, is an absolute temperature scale and starts from absolute zero.

The relationship between the absolute temperature on the Kelvin scale and the Celsius temperature is defined by a simple conversion formula: T(K) = t(°C) + 273.15. This formula expresses the temperature T in Kelvin as the temperature t in Celsius degrees plus 273.15. The reverse conversion, from Kelvin to Celsius, is represented by the formula: t(°C) = T(K) - 273.15. The other equations presented in the question appear to include irrelevant or incorrect elements and are not standard conversions between Celsius and Kelvin.

It's crucial to note that the Kelvin scale, unlike the Celsius and Fahrenheit scales, is an absolute temperature scale based on absolute zero, the theoretically lowest possible temperature. Therefore, there are no negative temperatures in Kelvin. This is one of the many reasons why it is used in scientific and engineering contexts.
