Are changes in state physical or chemical changes? Explain. What type of forces must be overcome to melt or vaporize a substance (are these forces intramolecular or intermolecular)? Define the molar heat of fusion and molar heat of vaporization. Why is the molar heat of vaporization of water so much larger than its molar heat of fusion? Why does the boiling point of a liquid vary with altitude?
The freezing point of cyclohexane is 6.50C, and its molal freezing point depression constant is 20.2C/m. When 2.00g of a solute is added to 100.0g of cyclohexane, the freezing point of the solution is 1.33C. What is the molar mass of the solute?
The enthalpy of vaporization of water is larger than its enthalpy of fusion. Explain why.
A student dissolves 27.2g of aniline, C6H5NH2, in 1.20102g of water. At what temperatures will the solution freeze and boil? Aniline is used in the polyurethane manufacturing process. Materials made from polyurethane include foams as pictured, spandex, hardwood floor coatings, dolly wheels, and many other end products.
Write a brief description of the relationships among each of the following groups of terms or phrases. Answers to the Concept-Linking Exercises are given at the end of the chapter. Solubility, intermolecular forces, partial pressure of a solute gas, temperature
12.105 Using the kinetic-molecular theory, explain why an increase in pressure produces more N2O4 in the following system: N2O4(g)2NO2(g)
explain why the hydrogen bond intermolecular forces are stronger than ordinary dipole-dipole intermolecular forces. You may use Coulomb’s Law to help justify your answer.
Description You will use an online simulation to manipulate and calculate the four properties of gases: Pressure, Volume, Quantity, and Temperature. You will also apply your knowledge to several scenarios. To begin, open the simulation, Gases Intro, from https://phet.colorado.edu/sims/html/gases-intro/latest/gases-intro en.html. This will open it in another window. Select the simulation box Intro at the bottom. When it opens, check Width to show the width of the box. You should leave the rest unchecked. We will only use Heavy Particles. Play around with the simulation to see how to adjust the volume/width (handle on left of box), temperature (bucket below with either ice or fire), and quantity (using the pump handle to right of the box). Keep the box sealed by keeping top door closed. When you are ready to do the experiments, reset the simulation by pressing the white eraser button on bottom right, make sure width is 10.0 nm, and set to heavy particles (purple gas molecules).…
If the temperature of a liquid is increased, what is the efffect on the vapor pressure?
3. It is a quantity of heat need to convert a mole of liquid into gas phase at a specified temperature? a. molar enthalpy of vaporization b. molar enthalpy of boiling c. molar enthalpy of freezing d. molar enthalpy of evaporation
A student wants to determine the melting point of water as part of an investigation into the strength of electrostatic forces. The student considers determining the freezing point of water instead. Is this a valid option? O No, it is not because the freezing point is not related to electrostatic forces. O No, it is not because the freezing point is not related to the melting point. O Yes, it is; and determining the freezing point is likely to be more accurate. O Yes, it is; but determining the freezing point is likely to be more difficult.
