A solution is called "ideal" when:
choose one:
a. the forces of attraction between solute and solvent molecules are somewhat smaller than between solute-solute molecules or solvent-solvent molecules.
b. the forces of attraction between solvent molecules exceed those between solute and solvent molecules.
c. the forces of attraction between solute molecules exceed those between solute and solvent molecules.
d. all intermolecular forces of attraction are the same, resulting in no net enthalpy change when the solution is formed from its components.
e. the forces of attraction between solute molecules and solvent molecules are much smaller than between solute-solute molecules or solvent-solvent molecules.
Homework Answers
Answer - (d) all intermolecular forces of attraction are same resulting in no net enthalpy change when the solution is formed from its components.
The interactive forces between solute molecule and forces between solvent molecules are equal, when solute and solvent mixed these forces will be same as between solute and solvent molecule. So net forces of attraction remain nil. There is no enthalpy change when solution is formed.

11. Consider an ideal liquid mixture (solution) of A and B, where the intermolecular interactions between A molecules are same strength as the intermolecular interactions between B molecules, and these are the same size as intermolecular interactions between A and B molecules. This means that upon mixing, AH = 0. Now for comparison, consider a nonideal mixture solution) of A and B, where the intermolecular interactions between A and B molecules are much weaker than the intermolecular interactions between either...

2. One of the assumptions of the Ideal Gas Law is that no forces of attraction between gas particles exist. Water is a polar substance and its molecules probably have very high forces of attraction, How would these forces of attraction affect the answer calculated above. That is, would you expect the calculated pressure to be lower or higher than the actual pressure. Explain. 0.00141 10.607 AULNO.108 zo 130 p0040124 oo I

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
