Microorganisms reduce carbonyl compounds to alochols stereoselectively. 5-chloro-2-pentanone is reduced to (S)-5-chloro-2-pentanol in this way. Distillation of this alcohol over sodium hydride gives a chiral cyclic ether. Write stereochemically correct structural formulae for the alcohol and the cyclic ether.
At 600 degrees C, the equilibrium constant for the reaction 2HgO(s) --> 2Hg (l) +O2 (g) is 2.8. Calculate the equilibrium constant for the reaction 1/2O2(g) + Hg(l) --> HgO (s)
1.00 mol Zn reacts with excess hydrochloric acid, 1.00 mol H2 gas is produced. At 25ºC and 1.00 atm= 101,325 Pa, this amount of H2 occupies 24.5 L (= 24.5 x10-3 m3). How much work is done by the chemical system.

When 4.70 g of a nonelectrolyte solute is dissolved in 915 mL of water at 21 degrees C, resulting solution exerts an osmotic pressure of 839 torr. What is the molar concentration of the solution?
solution of cesium phosphate d. 7.92 x 10^-15 M solution of Hg2+ and a saturated solution of H2S at a pH of 0.5.
A box of volume 20.0 L contains 1.50 moles of an ideal gas. This gas initially consists of a single molecular species, X (molar mass of 42.0 g/mol), at a temperature of 25.0 °C.
One student measure the pH of the following three solution (weak base, conjugate acid and buffer). Using this data, please calculate the pKa and pKb (show calculation).
the final temperature of both the water and metal is 32.81 degrees C. The specific heat of water is 4.184j/g*K. What is the speciic heat of the metal?
