Avoltaic cell is constructed with two silver-silver chloride electrodes, where the half-reaction is ag (s)c agcl (s) (aq) + e f= +0.222 v the concentrations of chloride ion in the two compartments are 0.0100 m and 1.55 m, respectively. at 25 °c, the cell emf is v.

The cell voltage as written is 0.13 V.

The equation of the reaction is; Ag(s) + Cl(aq) > AgCl(s) (aq) + e- = +0.222 V

Since  the cathode and anode are the same, E°cell = 0.00 V

We also know that;

Q =  [0.0100 M]/[ 1.55 M]

= 0.00645

From the Nernst equation;

Ecell = E°cell - 0.0592/n log Q

Where n = 1

Ecell = 0.00 - 0.0592/1 log (0.00645)

Ecell = 0.13 V

Explanation:

We must use the Nernst equation

1. Write the equation for the cell reaction

The cell reaction is

                                                                                         E°/V  

  Anode: Ag(s) + Cl⁻(1.55 mol·L⁻¹) ⇌ AgCl(s) + e⁻;       +0.222

Cathode: AgCl(s) + e⁻ ⇌ Ag(s) + Cl⁻(0.0100 mol·L⁻¹);  -0.222

 Overall: Cl⁻(1.55 mol·L⁻¹) ⇌ Cl⁻(0.0100 mol·L⁻¹)          0.000

Step 2. Calculate E

(a) Data

  E° = 0 V

  R = 8.314 J·K⁻¹mol⁻¹

  T = 25 °C

  n = 1

  F = 96 485 C/mol

[Cl⁻]_ prod = 0.0100 mol·L⁻¹

[Cl⁻]_ react = 1.55      mol·L⁻¹

(b) Calculations:  

T = 25 + 273.15 = 298.15 K

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
