Methanol, ethanol, and n-propanol are three common alcohols. When 5.00 g of each of these alcohols is burned in air, heat is liberated. Calculate the heats of combustion of these alcohols in kJ/mol.
(a) methanol (CH3OH), -22.6 kJ
(b) ethanol (C2H5OH), -29.7 kJ
(c) n-propanol (C3H7OH), -33.4 kJ
At a certain temperature, reaction has equilibrium constant (Kc) of 1.9 x10^19. Determine the equlibrium constant for the reaction based on this information at the same temperature.
Calculate the mass flow rate and power needed to run the compressor while assuming that oxygen can be treated as an ideal gas and that the gas at the entrance and at the exit is in local equilibrium.
A buffer solution is prepared by dissolving 1.51 g NH3 and 3.85 g (NH4)2SO4 in enough water to make 0.500 L of solution.
when a mixture of these two gases are compressed to a smaller volume, which way does the reaction shift to? the reaction is originally at 588 kelvins and has an equilibrium constant of "k"=0.0180
The concentration of the primary waste in the pond is 35 mg/L. All of a sudden, the process changes and the concentration of the waste in the stream coming into the pond jumps to 250 mg/L. The pond is 500,000 L and the flow rate of the waste comin..
