what are the typical detection limits for analyzing metals in solid and aqueous solution
The molality of an aqueous solution of a nonelectrolyte is 0.880 m. For pure water at 20 degree C: p^o = 17.5 torr k_f = 1.86 degree C/m k_b = 0.563 degree C/m a) What is the vapor pressure of the solution at 20.0 degree C? P = ________ torr b) What is the boiling point of the solution to the nearest 0.1 degree C? t = ______ degree C c) What is the freezing point of the solution to...
An aqueous BSA* solution in the tube on the left is in equilibrium with pure water in the tube on the right. The membrane that separates the two solutions is only permeable to water. When more BSA is added to the solution on the left, .. Why? aqueous BSA pure water A. the water level on the right increases B. the BSA solution level on the left increases C. no change in levels occur *BSA = Bovine serum albumin protein...
QIII. Observe the following Lab reaction and answer the questions that follow: Aqueous Solution Aqueous Solution Ca + Znco, Caco, + Calcium Zinc carbonate Zinc Calcium carbonate 1529 649 1929 29 104 a. Calculate the total mass of the reactants ? 256g b. How much amount of zinc is produced in the above reaction. long
1) The oxides of most metals are energetically “downhill” from the energy of the pure metal. Metals that oxidize generally gain weight in the early stages of oxidation. Do you want this behavior for “the gold standard,” which is a metal stored for long periods of time and used to calibrate dollars? Think about the thermodynamics. (15 pts.)
A 36.5% by mass of C6H12O6, aqueous solution is prepared in the lab. the density of the solution is 2.97 g/ml. what is the osmotic pressure of the solution at 42 OC ( R=0.08206 L*atm/mol*K)
Version 2 sider the phase diagram of an aqueous solution and that for pure water. Which of the following statements are true? A) The line representing freezing for the solution phase diagram is shifted to the left / of that for pure water. (B) The line representing freezing for the solution phase diagram is shifted to the right of that for pure water. C) The line representing boiling for the solution phase diagram is shifted to the left of that...
a) The vapor pressure of pure water at 30°C is 31.8 torr. An aqueous solution of urea had a vapor pressure of 29.3 torrat the same temperature. What is the mole fraction of urea in the solution? b) How many grams of sucrose, C12H22O11(MW=342), must be dissolved in 552 g H2O (MW=18.016) to give a vapor pressure 2.0 torr lower than of pure H2O at 20°C? The VP of H2O at 20°C is 17.5 torr.
