The vapor pressure of ethanol (C2H5OH) at 19 °C is 40.0torr. A 1.00-g sample of ethanol is placed in a 2.00 L containerat 19 °C. If the container is closed and the ethanolis allowed to reach equilibrium with its vapor, how manygrams of liquid ethanol remain?
Air conditioners not only cool air, but dry it as well. A room in a home measures 6.0 m * 10.0 m * 2.2 m. If the outdoor temperature is 30 °C and the partial pressure of water in the air is 85% of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? (Assume that all of the water must be removed from the air.) The vapor pressure for water at 30 °C is 31.8 torr.
Arrange the following molecules in order of increasing molar enthalpy of vaporization: CCl4, SiCl4, CH4, SiBr4 Why is SiBr4 < CCl4 but CCl4 < SiBr4 ? I understand that the bond length for CCl4 is stronger than the bond length for SiBr4 so why wouldn't the bond length for SiBr4 be weaker than CCl4 ?
