Chapter 8, Problem 12P
Summary Introduction

To draw: The structure of deoxyribose, guanine and phosphate along with the order (from most soluble to least) of their solubility in water.

Introduction:

The solubility in water is determined by hydrogen bonding or the presence of polar molecules. Molecules that have hydrogen atoms are involved in covalent interactions of hydrogen with highly electronegative elements like oxygen, or nitrogen.

Summary Introduction

To explain: The way in which the order of solubilities is consistent with the three-dimensional structure of double-stranded DNA.

Introduction:

The interactions between bases are due to hydrophobic stacking so that two or more nitrogenous bases are arranged with planes of their rings (bases) parallel 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
Indicate the correct options.1. The units of the transport number are Siemens per mole.2. The Siemens and the ohm are not equivalent.3. The Van't Hoff factor is dimensionless.4. Molar conductivity does not depend on the electrolyte concentration.
