The normal boiling point of liquid bromine is 58.8oC, and its molar enthalpy of vaporization is Delta Hvap = 29.6 kJ/mol.
(a) When Br2(l) boils at its normal boiling point, does its entropy increase or decrease?
(b) Calculate the value of delta S when 1.00 mol of Br2(l) is vaporized at 58.8oC.
Conjugation of the functional group in alkyl socyanates has little impact on the antisymmetric -N=O stretching vibration located near 2770/cm . Explain.
For the reaction shown below, Kp = 0.116 at 38.6 °C. Find the equilibrium partial pressures of ALL species if at the start of the reaction PCO = 1.17 atm and PCOBr2 = 1.4 atm
You have 50 ml of an 86% (w/v) glucose (C6H12O6) solution. How many grams of glucose are in the solution?
A cube of osmium metal 1.500cm on a side has a mass of 76.31g at 25°C. Calculate the mass of 0.1500L of benzene at this temperature.
Within this analogy, discuss how the shielding by core electrons is analogous to putting a frosted-glass lampshade between the lightbulb and your eyes, as shown in the illustration.
At 25 oC, experiment shows that the total pressure of the gases in equilibrium with the solid is 0.116 atm. What is the equilibrium constant Kp and Kc?
Assume that the metal rack is cooled from 240°F to 85°F, the temperature of the outlet water. The amount of heat removed from the retort walls in cooling from 240 to 100°F is 10 000 btu. Radiation loss from the retort during cooling is estimated a..
What is the maximum number of moles of AgCl that could be obtained from this mixture?
A 180 kiln is used for vitrifying ceramics. It is currently operating at 1025 , and the pressure is 1.100 . How many moles of air molecules are within the confines of the kiln.
Manganese forms the following oxide minerals: manganite (MnOOH), manganosite (MnO), pryolusite (MnO2), and hausmannite (Mn3O4).
When heated to 350 at 0.950 , ammonium nitrate decomposes to produce nitrogen, water, and oxygen gases.
Nitrogen dioxide (NO2) cannot be obtained in a pure form in the gas phase because it exists as a mixture of NO2 and N2O4. At 25°C and 0.98 atm, the density of this gas mixture is 2.7 g/L.
