Hypergolic propellants are fuels and oxidizers which ignite spontaneously on contact with each other.requiring no ignition source, hypergolics are ideal for spacecraft maneuvering systems as they provide an easy start and restart capability. Also, hypergolics do not pose the storage problems of cryogenic propellants (e.g., liquid oxygen and hydrogen) as they remain liquid at normal temperatures. This technology was used on the Apollo 11 Mission 40+ years ago.As part of the testing for a new thruster design, amounts of unsymmetrical dimethyl hydrazine, or UDMH [(CH3)2N-NH2; MW=60.1 g/mol] were reacted with dinitrogen tetroxide [N2O4; MW=92.1 g/mol]. The balanced equation for this reaction is shown below:(CH3)2NNH2(l) + 2 N2O4(g) → 3 N2(g) + 4 H2O(g) + 2 CO2(g)For one test, 721.2 grams of UDMH was completely consumed.

1)The production of authentic tequila is restricted to the blue agave and a defined geographical area in west-central Mexico. Two basic categories of tequila can be distinguished: “100% agave” and “mixed” tequila. High-quality “100% agave” tequila uses pure agave juice for fermentation and Mexican law states that these authentic tequilas must be bottled in Mexico. A mixed tequila is manufactured by adding up to 49% (w/v) of sugar from sugar cane for fermentation. The low-quality tequila is usually shipped in bulk containers for diluting and bottling in the importing countries. Due to frequent fraud in the labeled quality of tequila, there is a need to verify the authenticity of a tequila using chemical analysis. Figure 1 shows an ion chromatogram for an authentic 100% agave tequila and a commercial mixed tequila. The difference in anion content is due to the different sources of water used in final dilution and bottling steps. a) In reversed-phase liquid chromatography, a…

Estimate the standard enthalpy of formation of dichlorodifluoromethane, CCl2F2(g) (Fig. 12.20). This compound is also known as Freon-12 and was used as a refrigerant because of its low reactivity and high volatility. It and other related chlorofluorocarbons (CFCs) have been phased out because of their role in depleting the ozone layer in the outer atmosphere, asdiscussed in Section 20.6.
Dry nitrogen gas (100.0 L) was bubbled through liquid ethanol, C2H5OH, at a given temperature and the evaporated ethanol condensed; its mass was then measured. Using the data below, calculate the heat of vaporization (kJ/mol) of ethanol?
Chlorodifluoromethane (CHF2Cl) was widely used in the compression/cooling circuits of refrigeration or air-conditioning systems. Since the discovery that such compounds (HCFCs and CFC's) released into the atmosphere were a major cause of depletion of stratospheric ozone, newer refrigeration systems make use of certain hydrofluorocarbons (HFCs), which are degraded in the lower atmosphere, instead. Often, mixtures of such compounds are used. Suppose a sample of refrigerant gas consisting of a simple mixture of the gases pentafluoroethane (C2HF5) and difluorormethane (CH2F2) has a density of 3.06 g/L at 14 °C and 0.974 atm. Calculate the average molecular mass for this sample
