A solution of 75.0 g of benzene (C6H6) and 75.0 g of toluene (C7H8) has a total vapor pressure of 80.9 mmHg at 303 K. Another solution of 100.0 g benzene and 50.0 g toluene has a total vapor pressure of 93.9 mmHg at this temperature.
Find the vapor pressure of pure Benzene at 303 K
Draw all the structural isomers for the molecular formula C4H9Br. Be careful not to draw any structures by crossing one line over another; the system needs to know where you intend connections to be between atoms. I came up with 4 different struct..
How many mL of 6.0M H2SO4 are required to react with .80g of CuO according to the equation CuO
An object has a mass of 5.95g. Assuming the density of water is 1 g/mL, what is the volume of the object including air?
calculate the gasphase proton affinity of NH3. The lattice energy of NH4Cl may be estimated from Kapustinskii's formula using rN-Cl = 3.50 Å.
Write the balanced molecular equation, the total ionic equation, and the net ionic equation
Calculate the order of the reaction with respect to reactant C, the reaction rate constant, the overall order of reaction, and write the rate law for the reaction.
What is the final concentration if 75.0 mL of a 3.50 M glucose solution is diluted to a volume of 400.0 mL?
The initial concentration of some weak acid, HA, in an aqueous solution is 0.2150 M, at equilibrium the concentration of HA becomes 0.0955 mol/L.
By comparing the Charles's law equation to the linear equation, y= -0.171x + 46.837, where y is volume and x is temperature, determine the value of k.
Free radicals are important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the actions of sunlight on air pollutants, is formed in part by the following two steps.
If the volume of ocean water is 5.4*10^20 contains 4.1 percent sodium chloride ("salt") by mass and the density of the water is 1.86 g/mL.
Show that the proton condition for a NH4Cl solution is a linear combination of the mass balance equations and the charge balance equation.
