Balance each skeleton reaction, use Appendix D to calculate E°cell, and state whether the reaction is spontaneous:(b) Hg₂²⁺(aq)
Olegator [25]

The given reaction is not spontaneous.

We must recognize changes in oxidation states that take place across elements in order to balance these equations. To accomplish this, keep in mind following guidelines:

A neutral element on its own has an oxidation number of zero.For a neutral molecule, the total number of oxidations must be zero.The net charge of an ion is equal to the sum of its oxidation numbers.In a compound: hydrogen prefers +1, oxygen prefers -2, fluorine prefers -1.In a compound with no oxygen present the other halogens will also prefer -1.

One of the mercury atoms is oxidized from +1 to +2 in the simple aqueous ion, for a loss of 1 electron.

Oxidation half-reaction:

0.5 Hg^{2+} _{2} (aq) →Hg^{2+} (aq) + 1e^-

E^o _{ox} = - 0.92 V

The other mercury is reduced from +1  to zero in mercury metal, for a gain of 1 electron.

Reduction half-reaction:

0.5 Hg^{2+} _{2} (aq) + 1 e^- →Hg(l)

E^o _{red} = 0.85V

This is a disproportionation redox reaction !

Net reaction:

Hg^{2+} _{2} (aq) →Hg^{2+} (aq) + Hg (l)

E^o _{cell} = 0.85 - 0.92 = -0.07V

The cell potential is negative so this reaction is NOT spontaneous.

Prove electrode potential is concentration dependent
Nina [5.8K]
Electrode potential is concentration dependent as it is composed of two half-cells with same electrodes but different concentrations. One acting to dilute a more concentrated solution, while the other concentrates a more diluted solution — which then creates a voltage that is in equilibrium. This why we need both positive and negative sides of a battery as a power source and make something work.

Cellular respiration is when what energy from sugar/glucose is converted to cellular
Andrej [43]

Answer:

The correct answer is - cellular respiration is when <u><em>chemical</em></u> energy from sugar/glucose is converted to cellular <u><em>energy in the form of ATP</em></u><em><u>.</u></em>

Explanation:

Cellular respiration is a set of metbolic reaction that takes place inside the cell and breaking the sugars or nutrients to convert the chemical energy present in the nutrients into the cellular energy whic is used by cells that is ATP and release water and carbon dioxide as waste.

In this process the ammount of energy store in the cellular currecncy or ATP which is the form of energy that is utilized by the to perform its sunction. The chemical energy that is present in the nutrients or sugar is come from light energy which is stored in the nutrients by photosyntheis process.
