As a scuba diver descends under water, the pressure increases. At a total air pressure of 2.70 atm and a temperature of 25.0 *C , what is the solubility of N2 in a diver's blood? [Use the value of the Henry's law constant k calculated in Part A, 6.26*10^-4 mol/(l*atm).]
Assume that the composition of the air in the tank is the same as on land and that all of the dissolved nitrogen remains in the blood.
Given that the Ka for hypochlorous acid is 3.0x10^-8 determine the number of moles of sodium hypochlorite needed to prepare this solution.
At this temperature, calculate the number of moles of NO2(g) that must be added to 2.76 mol of SO2(g) in order to form 1.20 mol of SO3(g) at equilibrium.
What is the pH of 270.0 mL of an aqueous solution containing 0.525 g of the strong acid trifluoromethane sulfonic acid (CF3SO3H)?
If 0.25 mol of Br2 and .55 mol of Cl2 are introduced to a 3.0 L container at 400K, what will be the equilibrium concentration of Br2?
PCBs are transported through the environment in the vapor phase to Lake Superior. Let's assume that the flux to this lake is almost all due to rainfall, which has an average PCB concentration of 30 ng/L. The average depth of Lake Superior is 150 m..
The student then titrated 25ml of the same buffer with 0.1115M NaOH. The observed titration curve is shown before. what is the concentration of the weak acid in the buffer?
A current of 3.65 A is passed through a Fe(NO3)2 solution for 1.40 hours. How much iron is plated out of the solution
Which element has 55 neutrons, 36 electrons, 40 protons and has a mass of 95. I know its 95Mo but does it have a ion charge of +2,+4,or+6? I've tried +2 and +6 but its wrong. Help would be appreciated.
Assume you have a mixture of gases that contains 3.50 L of helium, some argon at 1.03 atm, and some neon at 27 degrees C. For which gas(es)
Draw one energy diagram showing both reaction pathways & label all transition states, intermediates and products as well as activation energies. you may assume that the overall reactions are both exergonic while the first step in each reaction is ..
Using the thermodynamic cycle in the tight binding KNI-764/HIV-1 protease example discussed in class, derive the Kapp= KKNI-764/(1+KAc-pepstatin[AcPepstatin]) for the apparent affinity constant (Kapp) for the competition assay between the weak (Ac..
A 1.013-g sample of ZnSO4xH2O is dissolved in an aqueous solution of BaCl2. The pure BaSO4 precipitate is filtered out of solution, dried, and its mass is determined to be 0.9400 g. What is the value of x in ZnSO4xH2O?
