Chapter 10: Q17E (page 584)

Explain why a hydrogen bond between two water molecules is weaker than a hydrogen bond between two hydrogen fluoride molecules.

Short Answer

Expert verified

The partially positive H and the larger partially negative F will produce a stronger hydrogen bond than the hydrogen connection formed by H and O.

Step by step solution

01

Definition of Hydrogen bond

A hydrogen bond is an electrostatic attraction between a proton in one molecule and an electronegative atom in other forms a weak link between two molecules.

02

Explanation of why hydrogen bond between two water molecules is weak

Because F has a higher electronegativity than O, the partial negative charge on F is bigger than that on O. As a result, the hydrogen bond created by the partially positive H and the larger partially negative F will be stronger than the hydrogen link formed by H and O.

The test tubes shown here contain equal amounts of the specified motor oils. Identical metal spheres were dropped at the same time into each of the tubes, and a brief moment later, the spheres had fallen to the heights indicated in the illustration. Rank the motor oils in order of increasing viscosity, and explain your reasoning:

Is it possible to liquefy nitrogen at room temperature (about 25 掳C)? Is it possible to liquefy sulfur dioxide at room temperature? Explain your answers.

Consider a cylinder containing a mixture of liquid carbon dioxide in equilibrium with gaseous carbon dioxide at an initial pressure of \({\rm{65}}\) atm and a temperature of \({\rm{2}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\). Sketch a plot depicting the change in the cylinder pressure with time as gaseous carbon dioxide is released at constant temperature.

Identify two common observations indicating some solids, such as dry ice and mothballs have vapour pressures sufficient to sublime.

Elemental carbon has one gas phase, one liquid phase, and two different solid phases, as shown in the phase diagram

  1. On the phase diagram, label the gas and liquid regions.
  2. Graphite is the most stable phase of carbon at normal conditions. On the phase diagram, label the graphite phase.
  3. If graphite at normal conditions is heated to 2500 K while the pressure is increased to 1010 Pa, it is converted into diamond. Label the diamond phase.
  4. Circle each triple point on the phase diagram.
  5. In what phase does carbon exist at 5000 K and 108 Pa?
  6. If the temperature of a sample of carbon increases from 3000 K to 5000 K at a constant pressure of 106 Pa, which phase transition occurs, if any?
