A high pressure container of methane gas which exhibits an absolute pressure of 200 atms at a temperature of O C. A large fire causes the temperature of the cylinder to rise to 1500 C. What is the final pressure in the cylinder? State the answer both in atms and psia. Assuming methane behaves as an ideal gas,
Someday, cars may be powered by clean H2/O2 fuel cells and electric motors. Under standard conditions, such a fuel cell can develop 1.229 volts. If the oxygen is obtained from air (at P=0.21 bar), what pressure of H2 would be required to develop 1..
What is the value of Kc for the decomposi- tion of ammonium carbamate into ammonia and carbon dioxide?
Why is direct nucleophilic substitution a poor method for preparing secondary and tertiary amines from primary amines
Name some factors, besides weight and cost effectiveness, that one might consider when choosing one brand of antacid over another. Explain.
Compound A had IR peaks at 3060, 3000-2850, 2750, 1715 cm^-1. It reacted with BH4- then H+ to form Compound B which had 1H NMR peaks of 7.2 to 7.4 (garbage, 5), 3.65(doublet, 2), 2.9 (sextet,1), 1.7 (singlet, 1) and 1.22 (doublet, 3). What are com..
The vapor pressure of ethanol is 60.1 torr at 25.0 degree C, and its molar heat of vaporization is 39.3kj/mol. Estimate the temperature at which the vapor pressure of ethanol would equal 350. torr?
At what temperature is the change in entropy for the reaction equal to the change in entropy for the surroundings?
We have noted that water level rises to 62.4mL when a piece of metal of 48 grams is dropped into 50.0mL of H 2 O in a graduated cylinder. Determine the density of this metal?
the amount of product formed in the reaction mixture was 12 micro-moles. If, in a separate experiment, one-third as much enzyme and twice as much substrate had been combined, how long would it take for the same amount (12 micro-moles) of product t..
Explain why selectivity in isocratic HPLC system ideally should not depend on eluent composition. (Use thermodynamic derivation to support your explanation).
What mass of CO2 and H20 would be produced during the combustion analysis of 0.1674 g of the cobalamin?
How much NaOH in grams is needed to prepare 546 mL of solution with a pH of 10.00? The molecular weight of NaOH is 40.0 g/mol. Hint: Since NaOH is a strong base it ionizes (disassociates) completely. The OH- concentration equals the initial concen..
