Determine the boiling point of a solution that contains 78.8 g of naphthalene (C10H8) dissolved in 722 mL of benzene (d = 0.877 g/mL). Pure benzene has a boiling point of 80.1°C and a boiling point elevation constant of 2.53°C/m.
water to give a solution that has a vapor pressure of 37.2 torr at 35 °C? Assume complete dissociation of the solute and ideal solution behavior
On a cold winter morning when the temperature is -13 degrees C, the air pressure in an automobile tire is 1.5 atm. If the volume does not change, what is the pressure after the tire has warmed to 15 degrees C?
Question- Calculate the experimental packing efficiency of KCl crystal (NaCl type) using a = 628 pm, r(K+ ) = 133 pm, r(Cl-) = 181 pm, and determine its ideal theoretical maximum based on the hard sphere model,
The activation energy of a certain reaction is 76.4 kJ/mol. How many times faster will the reaction occur at 42C than at 0C
What is the concentration of Cu2+ in the other half-cell? (Assume the concentration in the unknown cell to be the lower of the two concentrations.)
To determine the approximate mass of a small sherical shot of copper the following experiment is preformed: 125 pieces of shot are added to 7.9ml of water in a graduated cylinder and the volume becomes 8.3ml.
The reaction 2NO(g) + O2(g) 2NO2(g) is second order in NO as well as first order in O2. Explain when [NO] = 1 M and [O2] = 2.6 M, the observed rate of disappearance of NO is 0.00024180 M/s.
The half-equivalence of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted.
