A mixture of ethanol and 1-propananol behaves ideally at 36C and is in equillibrium with its vapor. If the mole fraction of the ethanol in the solution is 0.65, calculate its mole fraction in the vapor phase at this tempature.The vapor pressures of ethanol and 1-propanol are 108mmhg and 40 mmg respectively.
a) How many moles of water form when 5.00L of propane gas completely reacts? b) How many grams of CO2 are produced from 18.5 g of oxygen gas and excess propane? c) How many grams of H2O can be produced from the reaction of 8.50*10^22 molecules of ..
Calculate the change in entropy of the system and the surroundings and the total entropy change if four moles of an ideal gas is expanded isothermally
A 0.16-mole sample of nitrogen gas occupies a volume of 2.35L . What is the volume of 0.34mol of nitrogen gas under the same conditions
A system at equilibrium contains I2 (g) at a pressure of 0.41 atm and I (g) at a pressure of 0.32 atm. The system is then compressed to half its volume.
The temperature of a lead fishing weight rises from 26 degrees Celsius to 38 degrees Celsius as it absorbs 11.3 J of heat. What is the mass of the fishing weight in grams.
Explain how this reaction at equilibrium responds to the addition of heat? Please include any logic for why the reaction is endothermic or exothermic,
Cyclohexanol, C6H12O, has a heat of combustion of -890.7 kcal/mol. A sample containing only 0.708 g of cyclohexanol undergoes complete combustion in a bomb carlorimeter that has a heat capacity
A 2 mL sample was taken of a solution of barium iodate at 10 degree C. the sample was mixed with 2 mL of 0.5 M KI and 2 mL of 1M HCl. The transmittance of the mixture was read and compared to a calibration curve which indicated a concentration of ..
The next items refer to the result of mixing 400. ml of 0.10 M NaOH and 100.0 mL of 0.10 M Mg(NO3)2. Reaction as shown goes essentially to completion.
