a) 1.464 g of an unknown hydrocarbon (112.6 g/mol) burns in bomb calorimeter in excess oxygen. The heat capacity of the calorimeter,Cv, = 5.234 kJ/ºC and ?T =5.744 ºC. Find ?E for this hydrocarbon in kJ/mol.
b) Using the technique of the previous problem ?E was found to be -2,000.00 kJ/mol of an unknown liquid hydrocarbon at 298 K. In another experiment it was determined that for each mole of hydrocarbon, 5 moles of oxygen gas are consumed and 7 moles of CO2 gas and 7 moles of H2O liquid are produced. Find ?H per mole of this hydrocarbon (in kJ) at 298 K.
the final temperature of the cu? I tried to use Q=MS(delta)T and solve for the tinal temp instead of the change in temp but kept getting 45°c.
Equilibrium constant for the cell reaction is (A)100 .32/0.0591 (B)100.32/0.0295 (C) 100.26/0.0295 (D) e0.32/0.295
Explain why the rates of diffusion of nitrogen gas and carbon monoxide are almost identical at the same temperature.
For the reaction CH4+202=2H2O+CO2, calculate the percent yield of carbon dioxide if 1000. g of methane react with excess oxygen to produce 2300. g of carbon dioxide.
A ground-state H atom absorbs a photon of wavelength 94.91 nm, and its electron attains a higher energy level. The atom then emits two photons: one of wavelength 1281 nm to reach an intermediate level, and a second to return to the ground state.
