If 24.6 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 301 Kelvin and 1.01 atmospheres? Show all of the work used to solve this problem.
2 Li (s) + 2 H2O (l) 2 LiOH (aq) + H2 (g)
This sample was reacted with excess ammonia in diethyl ether at 0 c. The product mixture had a specific rotation of -29.9 degrees. If the specific rotation of pure (R) 1-phenyl ethanamine is +39.3 degrees. This reaction resulted in [X] percent inv..
what temperature should the tube be maintained to have a partial pressure of 1.0mm of O2 in the exit gas? Assume that the total pressure of the gas in the tube is 1.30atm.
For a mass of 0.010 g Mg and 5.0 mL of 1.00 M HCl, calculate the partial pressure of the resulting H2(g) in a flask with V = 145 mL at 25?C.
Guesstimate the extent of the dipole moment of H 2 O in Debye units, treating H 2 O as three point charges. suppose the O-H distance = 1.00 A, angle H-O-H =104°. The
