Interpretation Introduction

Interpretation:

The remaining mass of potassium -38 at 11:00 AM is to be predicted.

Concept introduction:

Half-life is defined as the time required for the number of nuclides to reach half of the original value. The remaining mass of a sample is calculated by the formula shown below.

R=S×(1/2)n

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.
