The heat capacity of a bomb calorimeter was determined by burning 6.79 g methane (energy of combustion 802 kJ/mol CH4) in the bomb. The temperature changed by 10.8C. a. What is the heat capacity of the bomb? b. A 12.6-g sample of acetylene, C2H2, produced a temperature increase of 16.9C in the same calorimeter. What is the energy of combustion of acetylene (in kJ/mol)?
Note Set #10 – week 12 Analytical Chemistry SPECTROSCOPY CONT. Raman Spectroscopy: the predominant form of IR spec today, extremely diverse uses, and simple to do o Raman’s original experiment: filters only violet light from the sun onto sample using telescope, then scattered light is filtered to only pass green light into detector, in his case, his own eye. o Does NOT analyze an absorption/emission event, only scattering o Raleigh scattering: the majority of light (photons) emitted from a vibrational spectrometer is the same wavelength as the light that originally went in Stokes scattering: the energy of scatted light is weaker than incident
