Internally reversible compression
Air initially occupying 1 m3 at 150 kPa, 20°C undergoes an internally reversible compression during which PV^n = constant to a final state where the pressure is 600 kPa and the temperature is 120 C determine the value of n.

The flask is heated to 100°C and the reaction is then allowed to go to 100% completion. If the total pressure of all gases in the flask at 100°C is 950. torr when the reaction is complete, what was the mass of nitromethane sample used
An ideal gas at a given state expands to a fixed volume by two types of processes: (i) isobaric, (ii) isothermal. For which case is the work done greater?
Although pyrrole is a much weaker base than most other amines, it is a much stronger acid (pKa ≈ 15 for the pyrrole versus 35 for diethyl amine). The N-H proton is readily abstracted by base to yield the pyrrole anion, C4H4N. Explain.
Calculate the rms veloctiy of each gas at this temperature. b) Calculate the average kinetic energy per mole and per molecule for each gas.
Draw structural formulas (full or condensed) and give the molecular formulas for the following compounds. a)2-methylpropane b)2,4-dimethylpentane c)2,2-dimethylpentane
An attempt at synthesizing a certain optically active compound resulted in a mixture of its enantiomers. The mixture had an observed specific rotation of 11.0°. If it is known that the specific rotation of the R enantiomer is -31.0°, deter
For a mass of 0.010 g Mg and 5.0 mL of 1.00 M HCl, calculate the partial pressure of the resulting H2(g) in a flask with V = 145 mL at 25?C.
1) the symbols for the elements in the compound. 2) the oxidation numbers of the elements involved and write them as superscripts to the right of the elemental symbols
At 25 °C only 0.0990 mol of the generic salt AB3 is soluble in 1.00 L of water. What is the Ksp of the salt at 25 °C?
