On top of one of the peaks in Rocky Mountain National Park the pressure of the atmosphere is 500. torr. Determine the boiling point of water at this location. The heat of vaporization of water is 40.7 kJ/mol.
The equilibrium of Fischer esterification reactions in general is slightly towards product formation. The equilibrium can be made more favorable for product formation by all of the following except
15.0 mL of 0.400 M Hno3 Solution is titrated with 0.600 M KOH solution . Calculate pH of the solution when12.0 mL of KOH is added ?
Glycerol esterified with three fatty acids is called a sphingolipid d. Waxes are esters of long-chain alcohol and long-chain fatty acid e the short hand notation for fatty acid
If I put a methanol solution of m-THPC into a 10.0 mm pathlength cuvet, and observe an absorbance of 0.132 (no units) at 652 nm, what is the concentration of the solution? (Assume there are no other solutes present in the methanlo.
30.3 g of chromium(III) oxide reacts with 10.8 g of aluminum to produce chromium and aluminum oxide. If 20.7 g of chromium is produced, what mass of aluminum oxide is produced?
A 15.00 mL sample of unknown concentration of sulfuric acid is precititated with excess lead(II) nitrate and a precipitate of lead(II) sulfate is collected.
Give the structure that corresponds to the following molecular formula and 1H NMR spectrum: C4H10O2: ? 1.36 (3H, d, J = 5.5 Hz); ? 3.32 (6H, s); ? 4.63 (1H, q, J = 5.5 Hz)
A baseball weighs 5.17oz . What is the kinetic energy in joules of this baseball when it is thrown by a major-league pitcher at 91.0mph. By what factor will the kinetic energy change if the speed of the baseball is decreased to 55 {\rm mph}
Two manufacturing plants need 1.0x104 kg of Al each week. One plant produces the Al from bauxite (Al2O3) and the other produces Al from recycled cans. Recovering Al via recycling consumes only 5% of the energy it takes to manufacture aluminum from..
