53.5 g of an ideal gas of molecular weight = 10.5 g/mol is confined at a pressure of 50 kPa. The density of the gas is 0.164 g/L. Compute the temperature of the gas in degrees Celsius.
similarly, what happens if cellulose is reacted with maleic anhydride C4H2O3? Again, how is the cellulose molecule/structure altered and what are the reaction by-products?
What should be the concentration of the NaCl solution (in g/L) so that it will have the same osmotic pressure as the blood at 37 deg C
The normal boiling point of ethanol is 78.4 degrees C, and at this temperature ?vapHθ = 38.7 KJ mol-1. Calculate the value to which the pressure must be reduced to boil ethanol at 25 degrees C in a vacuum distillation.
CO + Cl2 COCl2 K = 4.6 x 10^9 If the concentration of the product were to double what would happen to the equilibrium constant
What is the solute and solvent of Antifreeze? What is the solute and solvent of Pepsi? What is the solute and solvent of Sterling Silver?
100 mL of 0.06 M TRIS hydrochloride (C4H12ClNO3) is titrated with 1.0 M sodium hydroxide (NaOH). The titration curve is shown. What is the approximate pKa
What absorption is diagnostic of benzophenone and not present in benzhydrol (give frequency and functional group); and what absorption is diagnostic of benzhydrol and not present in benzophenone
A buffer solution is prepared by mixing 50.0mL of 0.300 M NH3(aq) with 50.0mL of 0.300 M NH4Cl(aq). The pKb of NH3 is 4.74. NH3 + H20 ----> NH4+ + OH-
Arrange the members of the following set of elements in order of increasing first ionization energies. (Use the drop down lists to indicate your choice, with 1 as the smallest IE and 6 as the largest IE.)
