For the reaction below, Keq = 2.62x10–7(at 1000. C). If you place 12 atm of nitrogen gas and 36 atm of hydrogen gas in a 40.0 L reaction flask, calculate the mass of ammonia that will be present once the reaction comes to equilibrium. Give your answer in grams, and make sure you always record the unit as well as the value!
N2(g) + 3 H2(g) ↔ 2 NH3(g)
While ethanol (CH3CH2OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene
(CH2CH2) with water vapor at elevated temperatures.
A chemical engineer studying this reaction fills a 125 L tank with 57. mol of ethylene gas and 13. mol of water vapor. When the mixture has come to equilibrium
she determines that it contains 53.5 mol of ethylene gas and 9.5 mol of water vapor.
?
The engineer then adds another 19. mol of ethylene, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is
reached the second time. Round your answer to 2 significant digits.

Determine the total pressure in the flask when 1.02 atm of Oz is added to a 1.95 L flask containing 145 mL ethanol (CH3CH2OH). The density of
ethanol is 703.00 kg/m. The temperature remains at 100 °C throughout the reaction.
Note that the total pressure is calculated by adding up the pressure of ALL gases (O2, CO2, and H2O in this case).
