Limonene (MW 136) is a pleasant smelling liquid found in lemon and orange peels. The bp of limonene is 175, but it co-distills with water at 97.5. If the vapor pressure of water at 97.5 is 690 mm Hg, what percentage of the steam-distillate is limonene?
A reaction mixture initially contains 2.8 M H2O and 2.6 M SO2. Determine the equilibrium concentration of H2S if Kc for the reaction at this temperature is 1.3 × 10-6.
Energy level of electrons in atoms - The 3s level in hydrogen has a lower energy than the3d level in hydrogen.
If you have 230 mL of water at 25 deg celcius and add 140 mL water at 95 deg celcius. What is the final temperature of the mixture?
A vapor composed of 0.20 mole fraction ethanol and 0.80 mole fraction acetic acid at 120.0 mmHg (absolute), is in equilibrium with a liquid phase also composed of ethanol and acetic acid. Assume that the liquid is an ideal solution and apply Raoul..
If 100mL of 0.01 M CaCl2, 100mL of 0.01 M Sr(NO3)2 and 100 mL of 0.01 M Na2SO4 are mixed together; what is the Ca2+ concentrationin solution and which precipitates will form?
The endpoint corresponds to the equivalence point. D. At the equivalence point the amount of reagent added does not yet equal to the amount of analyte present
20.0 mL of 0.250 M calcium nitrate are mixed with 25.0 mL of 0.150 M potassium nitrate. How many grams of product will form
The initial temperature of the cold water was 21.00C and of the hot water, 29.15C. The maximum temperature of the mixture was found to be 24.81C. Assume the density of water is 1.0g/ml and the specific heat 4.184J. Determine the temperature change..
