If acetic acid has a pure vapor pressure of 20 torr at 30 degrees C and acetaldehye has a pure vapor pressure of 1000 torr at 30 degrees C, a mixture of 12 moles of acetic acid and 8 moles of acetaldehye would have what total vapor pressure?
A. 412 torrB. 510 torrC. 612 torrD. 608 torrE. 408 torr
A gas expands and does P-V work on the surroundings equal to 261 J. At the same time, it absorbs 216 J of heat from the surroundings. What is the change in energy of the system?
The boling point of water in city a is 94 degrees celcius and in city b it is 97 degrees celcius. which is at the higher elevation.
A cylinder contains a mixture of hydrogen and chlorine molecules. Compare without doing any calculations
What is the new pressure, in atm,when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas?
When gases are collected using displacement of water,some water vapor mixes in with the gas being collected.35.2 ml of H2 gas was collected over water at a temperature of 21 Celsius degree.
The atomic mass in g mol of Fe=55.85, S=32.07 O=16, calculate the number of moles of the negative ions present in 7.45g of iron (III) sulfate.
The combustion of 135 mg of a hydrocarbon produces 440mg of CO2 and 135 mg of H2O. The molar mass of the hydrocarbon is 270 g/mol.
The volume of NaOH added at the equivalence point was 5.15 mL. Calculate the concentration of the HCl solution
Copper has two isotopes: Cu-63 (abundance = 69.2%, mass = 62.930 amu) and Cu-65 (abundance = 30.8%, mass = 64.928 amu). Calculate the (average) atomic mass of copper.
Hydrogen Sulfide gas has toxicity comparable to Hydrogen Cyanide, but because of its intense odor its presence is observed at concentrations well below toxic levels.
A 20.00mL sample of H3Y was titrated with 0.1000 M NaOH. The first equivalence point was reached after the addition of 14.98mL of base. The second equivalence point was reached after the addition of 30.03mL.
