The oxidation state for sulfur atom in the given H 2 S species has to be determined. Concept introduction: Oxidation number: The oxidation number of an element is zero. The oxidation number of a monoatomic ion equals its charge. The oxidation number is zero for the summation of the oxidation numbers complete atoms in a complete formula. The charge on the ion is equal to the summation of the oxidation numbers of complete atoms in poly atomic ion. The oxidation state of alkali metal ( Li, Na, K, Rb, Cs ) is + 1 , and alkaline earth metal is (Be, Mg, Ca, Sr, Ba) is + 2 . The oxidation state of hydrogen is + 1 (except in bonding with metals), the oxidation state of oxygen is − 2 .

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?
