solution of water (K_f}=1.86 C/m) and glucose freezes at - 2.35 C. What is the molal concentration of glucose in this solution? Assume that the freezing point of pure water is 0.00 C.
If a 128 gram sample of H2O at 75 degrees Celsius were mixed with a 55 gram sample of H2O at 38 degrees Celsius, what would the final temperature of the mixture be?
Use the initial volume of acetic acid, the volume of NaOH required to reach the equivalence point and the value of the molarity of NaOH that you obtained when you standardized this solution against KHP in the strong-acid/strong-base experiment to
When Dr. Farrell was a graduate student, he prepared a buffer of pH = 8.0 from Sodium Acetate. Why would the casual observer to this buffering faux pas think he had the intellectual agility of a small soap dish?
The total molarity of acid and conjugate base in this buffer is 0.100 . A student adds 9.00 of a 0.250 solution to the beaker. How much will the pH change? The of acetic acid is 4.760.
Air at 101.3 kPa and 15°C enters and leaves an axial-flow compressor stage with a velocity of 150m/s without swirl. The stage has a tip radius of 56cm and a hub radius of 35cm and rotates at 8000 rpm.
Calculate the temp in degree celcius after thermoequillibrium is reached, assume no heat lost to the surroundings. The enthalpy of fusion of ice is molar heat = 6.007 kJ/mol, and the molar heat capacities of ice and water are 38 and 75 J/mol K res
