a certain substance has a heat vaporization of 45.50kj/mol. At what kelvin temperature will the vapor pressure be 3.0 times high than it was 295k?
The Greek mathematician Archimedes is credited with discovering how to verify the amount of pure gold in an irregularly shaped object (e.g., a crown) by placing it in water. How much water should be displaced by a pure gold object having a mass of..
A solution is prepared by dissolving 5.32 grams of potassium nitrite (a food preservative, as Clark Griswold would explain) into about100 ml of DI water in a volumetric flask. Enough water is then added to give a total volume of 250.0 ml. What are..
At 450 K the equilibrium concentrations for the following reaction was measured and used to calculate the kc value of 0.0431. What is the value of Kp for the Reverse reaction under the same conditions
Calibration standards. Transfer 1.00, 5.00, 10.00, 15.00 and 20.00 mL aliquots of 10ppm F- solution to 100 mL flasks. Add 50 mL of TISAB containing CDTA to each
Calculate deltaG for this reaction at 298K in kJ. What can be said about the spontaneity of the reaction at 298K? (1) spontaneous in the reverse direction
how much energy is liberated when 366 g of mercury c0.139jg degrees celsiuscools from 77.0 to 12.0 degrees
More gas is then added to the container until it reaches a final volume of 13.3 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
Your starting mixture contains both KCl and KClO3. Suppose that your starting mixture weighed 2.040 grams total, and suppose that you dertermined during your reaction that you produced 0.0072 mols of O2
Problem- If 10.0 kj of heat are added to a 15.5 g ice cube at -5.00 degrees C what will be the resulting state and temperature of the water
What is the definition of an adverse drug reaction? clinical pharmacology
