A chemistry student needs 80.0mL of acetone for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of acetone is 0.790g cm^-3.
The atmospheric sulfur dioxide concentration over a certain region is 0.12 ppm by volume. Calculate the pH of the rainwater due to this pollutant. Assume the dissolution of SO2 does not affect its pressure.
Circle the compound in each pair that you would predict to be more soluble in water. Give a very brief explanation for your choice. a. Nitrogen gas or Hydrogen fluoride gas b. Quartz crystal or (NH4)2SO4 crystal
From the values of ?H and ?S, predict which of the following reactions would be spontaneous at 25 degrees celsius. Reaction A: ?H = 10.5 kj/mol, ?S = 30.0 J/K*mol Reaction B: ?H = 1.8 kj/mol, ?S = -113 J/K*mol
The Ksp value for the dissociation of barium nitrate is 0.00464. The molar solubility of barium nitrate is consequently 0.105 M. If the concentration of the barium ion in a saturated solution of barium nitrate was raised to 0.178 M (this is not th..
