As a scuba diver descends under water, the pressure increases. At a total air pressure of 2.89 atm and a temperature of 25.0 celcius, what is the solubility of N_2 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.
what is the underlying electronic reason for all periodic trends?

In an equilibrium mixture the partial pressures of SO 2 and O 2 are 0.125atm and 0.460atm , respectively. What is the equilibrium partial pressure of SO 3 in the mixture?
Consider the following precipitation reaction 2 Na3(PO4)2(aq) + 3CuCl2(aq) ----> Cu3(PO4)2 (s) + 6 NaCl (aq). What volume of 0.168 M NaPO4 solution is necessary to completely react with 91.4 mL of 0.117 M Cucl2
A gas occupying 28mL at standard conditions is heated to 18C while the pressure is reduced to 0.98221 atm. What is the new volume occupied by the gas? Answer in units of mL.
A chemist must prepare 0.9 L of sodium hydroxide solution with a pH of 13.40 at 25 C. He will do this in three steps: Fill a 0.9 L volumetric flask about halfway with distilled water.
i am working on polymer blends. the components of blend are a homopolymer and its copolymer. i am investigating their
Calculate the energy change for the reaction K(g) + I(g) → K+(g) + I- (g) given the following ionization energy (IE) and electron affinity (EA) values. IE K = 419 kJ/mol, IE I = 1010 kJ/mol; EA K = 48 kJ/mol. EA I= 295 kJ/mol
Acetylene (C2H2) can be produced from the reaction of calcium carbide (CaC2) with water. Draw the localized electron orbital model (hybridized orbital model) for the acetylide anion (C22-), showing ?, ?, and lone pair electron orbital.
the average soil organic carbon content = 0.01%. assume that soil organic carbon is the primary sorbent and that degredation and dispersion are negligible.
For a particular orbital, as one goes away from the nucleus along the z-axis, the probability desity decreases to zero, then increases, and finally decreases without increasing a second time. This is consistent with
