The solubility of N2 in blood at 37 oC and at a partial pressure of 0.80 atm is 5.6 X 10-4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 4.0 atm. Assume that the total volume of the blood in the body is 5.0 L. Calculate the amount of N2 gas released (in liters at 37oC and 1 atm) when the diver returns to the surface of the water, where the partial pressure of N2 is 0.80 atm.
Use the Henderson-Hasselbalch equation to calculate the of each solution: a solution that contains 0.600% C5H5N by mass and 0.960%
Compound E was heated with bromine and aqueous sodium hydroxide to give compound F (C7H9N). Compound F was treated with cold sodium nitrite and an excess of hydrochloric acid a colorless gas was evolved, and when the resulting liquid reaction mixt..
To identify a diatomic gas (\rm X_2), a researcher carried out the following experiment: She weighed an empty 1.00-\rm L bulb, then filled it with the gas at 1.10 \rm atm and 23.0 ^\circ\rm C and weighed it again.
A solution is prepared by dissolving 159 g sucrose (C12H22O11) in enough water to produce 1.40 L solution. What is the molarity of this solution?
Calculate the fraction of atoms in a sample of argon gas at 400K that have an energy of 10.0 KJ or greater.
The mixture was stirred, causing all of the sample to dissolve. The excess HCl in the solution required 94.9 mL of 0.128 M NaOH for complete neutralization in a titration. What was the molecular formula of the white substance
Assume that aspartame is a molecular solid and does not ionize when it dissolves in water. Kf values are given here.
Compound A, C14H10, absorbed only 2 equivalents of H2 on catalytic hydrogenation over a Pd/C catalyst to yield compound B, C14H14. On ozonolysis, compound A gave only benzoic acid, C7H6O2. Draw the structure of compound B.
Label each bond in the following molecules as polar or non polar (make sure you are describing the bond not the molecule). CH4
Determine q for the acid-base reaction, assuming that the liquids have densities of 1.00 g/mL and the same heat capacities as pure water.
Calculate the initial rate of a first-order reaction if the concentration of reactant is 0.63 M and the half-life is 6.9 s
