Which of the following ideal aqueous solutions would be predicted to have the highest osmotic pressure
Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What is the molar concentration of {H_3O^+} in a cola that has a pH of 4.240? Express your answer with the appropriate units
Using the same assumptions and approximations you used in lab, determine the molar enthalpy change (in kJ/mol) for the reaction below, assuming that CH3CO2H dissociates completely in water.
A feed mixture of ethanol and water is 40 mole % ethanol. The feed is at 200 degrees Celcius and is at a high enough pressure that it is liquid. It is input into the column through a valve, where is flashes. Column pressure is 1 kg/cm^2. Find the ..
