At 25 degree Celsius, an aqueous solution containing 35.0wt% H2SO4 has a specific gravity of 1.2563. A quantity of the 35% solution is needed that contains 195.5kg of H2SO4
(a) Calculate the required volume (L)of the solution using the given specific gravity.
The reversible conversion of phosphorus pentachloride gas into phosphorus trichloride and chlorine gases has Kc = 2.68 at exactly 340oC. If 8.42mmol PCl5 are placed into a 125ml flask, what will be the partial pressures of each component at equili..
A 4.50-g sample of LiCl at 25.0C dissovles in 25.0mL of water also at 25.0C. Th final equilibrium temerpature of the resulting solution is 60.8C
15.0 grams of an unknown sugar was dissolved in water and the final volume of the solution was brought up to 1.00 L. The osmotic pressure of this solution was determined to be 2.44 atm at 25°C. Which of the sugars below was most likely the unknown..
The first point should be at -56.8 degrees Celsius and the last point at 150.0 degrees Celsius. Do not connect the points with a line.
Dehydrohalogenation of (2R, 3R)-2-bromo-3-methylpentane by a bimolecular reaction produces only (E)-3-methyl-2-pentene and 3-methyl-1-pentene as products. Provide a mechanistic explanation as to why (Z)-3-methyl-2-pentene is not formed.
Calculate pCu2+ at each of the following points in the titration of 50.0 mL of 0.001 M Cu 2+ with 0.001 M EDTA at pH 11.00 in a solution whose NH3 concentration is somehow fixed at 0.100 M:
