Predict the aqueous phase equilibrium concentration of phenanthrene at 25*C if the values for this compound are Cs = 1.1 mg/L, P^v = 1.6 x 10^-7 atm, KH = 4.0 x 10^-5 atm*m^3/mol, and logKow = 4.52.
Calculate the amount of heat required to completely sublime 78g of solid dry ice at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3kJ/mol .
Explain why it is unnecessary to run both of the following reactions: zinc + copper (II) sulfate, copper + zinc sulfate
If 1.0 l of 0.10 M sodium phosphate is mixed with 1.0 l of 0.10 M magnesium nitrate, magnesium phosphate is produced. Calculate the concentration of each ion when the reaction is finished and the mass of precipitate.
that the reaction was endothermic. If the enthalpy of reaction is negative, then we say that energy was released or that the reaction was exothermic. Most chemical reactions are exothermic.
The percent transmittance, %T, reading on a Spectronic 20 for a certain solution is found to be 45%. Calculate the absorbance for the solution
how many grams of carbon dioxide are produced when 23.5 g of 1-pentanol react with excess oxygen in a combustion reaction?
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching frequency, we would not have expected to observe the latter stretching mode in the infrared spectrum. Why
a rigid container is filled with liquid acetone at 20 degrees C and 1 bar. through heat transfer at constant volume, a pressure of 100 bar is generated
The enthalpy of formation of ethanol, C2H5OH, is -277.o kJ/mol at 298.15K. Calculate the enthalpy of combustion of one mole of ethanol, assuming that the products are CO2 and H2O
A student determined the molar mass of an unknown non-electrolyte compound by measuring the freezing point depression of an aqueous solution of the compound.
