The aqueous solutions of three compounds, as shown in the diagram, are to be identified as nonelectrolyte, weak electrolyte, or strong electrolyte. Concept introduction: The process by which a compound produces ions in a solution upon dissolution is called dissociation. An electrolyte is a substance that dissociates to produce ions when dissolved in water. Due to the formation of ions, electrolytes can conduct electricity. A nonelectrolyte isa substance that does not dissociate to produce ions. Hence, they cannot conduct electricity. The two types of electrolytes are strong and weak. The strong electrolytes completely dissociate into their constituent ions upon dissolution. Thus, they are good conductors of electricity. The weak electrolytes do not dissociate completely upon dissolution. The solution of a weak electrolyte contains very few ionsand unionized molecules predominantly. Hence, conducts less electricity.

An expression for the root mean square velocity, vrms, of a gas was derived. Using Maxwell’s velocity distribution, one can also calculate the mean velocity and the most probable velocity (mp) of a collection of molecules. The equations used for these two quantities are vmean=(8RT/πM)1/2 and vmp=(2RT/M)1/2 These values have a fixed relationship to each other.(a) Arrange these three quantities in order of increasing magnitude.(b) Show that the relative magnitudes are independent of the molar mass of the gas.(c) Use the smallest velocity as a reference for establishing the order of magnitude and determine the relationship between the larger and smaller values.
The reaction of solid dimethylhydrazine, (CH3)2N2H2, and liquefied dinitrogen tetroxide, N2O4, has been investigated for use as rocket fuel. The reaction produces the gases carbon dioxide (CO2), nitrogen (N2), and water vapor (H2O), which are ejected in the exhaust gases. In a controlled experiment, solid dimethylhydrazine was reacted with excess dinitrogen tetroxide, and the gases were collected in a closed balloon until a pressure of 2.50 atm and a temperature of 400.0 K were reached.(a) What are the partial pressures of CO2, N2, and H2O?(b) When the CO2 is removed by chemical reaction, what are the partial pressures of the remaining gases?
