The lowering of vapor pressure is expressed as Raoult's law. An ideal solution obeys Raoult's law. Discuss the reasons why real solutions differ from Raoult's law.
Therefore an answer in U.S. customary units, such as miles per hour would not be accepted as correct. A car traveling with constant speed travels 150 km in two hours. What is the speed of the car?
Calculate the approximate SO 2 mass emission in lb/day.
Calculate delta Hvap of pure alcohol using clausius-clapeyron equation. At 19 C vapor pressure for pure alcohol is 40 torr. At 35 C vapor pressure for pure alcohol is 100 torr
what purpose does sodium carbonate serve during the extraction of caffeine from tea leaves?
(i) Is the system in equilibrium? If not, which direction must the reaction proceed for equilibrium to be established? (ii) What is the Kp for this system at equilibrium?
If 3.50ml of vinegar needs 42.0ml of 0.130M NaOH to reach the equivalence point in a titration, how many grams of acetic acid are in a 1.20qt sample of this vinegar?
A coffee-cup calorimeter contains 140.0 g of water at 25.2 *C. A 122.0 g block of copper metal is heated to 100.4 *C by putting it in a beaker of boiling water.
The concentration which remains after 20 minutes is 80 mg/L. Determine the reaction order and the rate constant (with appropriate units).
At what temperature (celsius) will the rate constant for the reaction be 140.0 s-1? Use the conversion Kelvin = C + 273.15
The next question was this: "What is the PH at it's equivalence point? AS part of your answer, define equivalence point. What does it mean for a substance to be at its equivalence point?"
Calculate and plot the points where 0.00, 5.00, 10.00, 20.00, 25.00, 30.00, 35.00, 40.00, 45.00, and 50.00 mL of 0.075M KOH has been added
Calculate the pH of a solution prepared by dissolving 0.30 g of BaO in enough water to make 0.800 L of solution.
