The H2+ molecular ion has an equilibrium bond length equal to twice the Bohr radius, a0. Using the LCAO bonding orbital 0.5614(1sA+1sB), compute the electron density along the internuclear axis at a point that is 8 pm from the midpoint of the bond.
A buffer was prepared by mixing a solution that is 0.285 M in HA and 0.385 in A-. The pH of this buffer was 4.435. then to 405 mL of this buffer solution was added to 21.5 mL of 2.0 M HCl. What is the pH of this new solution?
63.0 mL of a 1.20 M solution is diluted to a volume of 208 mL. A 104-mL portion of that solution is diluted using 157 mL of water. What is the final concentration.
Calculate the Molarity of a 0.074 M solution of ethyl alcohol in water at 25 degrees C. (Assume the density of the solution at such a low concentration is equal to that of water at 25 degrees C, 0.997 g/mL.)
A solution contains 1 x 10-3 M Fe2+ and 2 x 10-10 M Fe3+. As the pH of the solution is raised, which iron hydroxide will precipitate first (i.e., ferrous hydroxide, Fe(OH)2(s) or ferric hydroxide, Fe(OH)3(s)). At what pH will this occur?
