Chapter 2, Problem 2E

(a)

Interpretation Introduction

Interpretation:

The better Lewis structure for CO2 should be selected and the reasoning should be explained.

Concept Introduction :

Rules for determining the best Lewis structure

  1. Smaller formal charges are preferred over larger formal charges
  2. Negative formal charges should reside on more electronegative atoms
  3. Like charges should not reside closer to each other.

Formal charge can be determined by following formula.

  Formal charge = Group number - No. lines - No. of dots

(b)

Interpretation Introduction

Interpretation:

Whether the choice in part (a) is consistent with the experimental data should be discussed.

Concept Introduction :

Rules for determining the best Lewis structure:

  1. Smaller formal charges are preferred over larger formal charges
  2. Negative formal charges should reside on more electronegative atoms
  3. Like charges should not reside closer to each other.

Four liters of an aqueous solution containing 6.98 mg of acetic acid were prepared. At 25°C, the measured conductivity was 5.89x10-3 mS cm-1. Calculate the degree of dissociation of the acid and its ionization constant.Molecular weights: O (15.999), C (12.011), H (1.008).Limiting molar ionic conductivities (λ+0 and λ-0) of Ac-(aq) and H+(aq): 40.9 and 349.8 S cm-2 mol-1.
Determine the change in Gibbs energy, entropy, and enthalpy at 25°C for the battery from which the data in the table were obtained.T (°C)          15           20          25         30          35Eo (mV)   227.13   224.38   221.87   219.37   216.59Data: n = 1, F = 96485 C mol–1
