The type of solid which give simpler X-ray diffraction pattern has to be identified and the same has to be justified. Concept introduction: There are two distinct categories of solids – crystalline solids and amorphous solids. In crystalline solids, the components are neatly stacked with regular pattern repetitively in a long range order. This is the characteristic feature of crystalline solids. Amorphous solids lack such feature that the components are arranged quite randomly. Diffraction is a phenomenon of scattering of a beam of light into various directions from a regular array of points or planes. X-ray diffraction is an experimental method used to study the structure of crystalline solids.

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?
