Answer: 3
Tetradecanol is in a condensed phase the whole time because solid and liquid phases are considered condensed phases because the force of attraction between the molecules allows them to condense at lower temperatures.

*Explanations should be brief. Draw a box around each final answer, if applicable.* 1. Consider intermolecular forces and kinetic energies with respect to a solid and a liquid. Explain why molecules in a liquid are free to move past each other, while molecules in a solid are held in fixed positions. 2. Use your knowledge of intermolecular forces to provide an explanation for why the boiling point of 2-hexanol is higher than the boiling point of 2,3-dimethyl-2-butanol. Be sure to...

1) Use the Energy-Interaction Model to explain whether the following statement is true or false: "A quantity of ice at 0℃ must contain less total energy than the same quantity of water at 0℃.2) According to the definition of heat in the online reading, can an energy system contain a certain amount of heat? Explain.3) Imagine that you place a piece of copper with an initial temperature of 20℃ in contact with some liquid water with an initial temperature of...

Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...
