You will check the outcome of reaction via infra-red spectroscopy: what are the diagnostic functional group peaks for the following compounds? You should also indicate the stretching motions responsible for absorbance. Dilantin benzil (unreacted starting material) Urea (unreacted starting material)

ui tu uid ausulualle ui paitiai rehection of light, where the amplitude of in-phase photons becomes reduced. Part B Reset the PHET simulation (using the button in the lower right) and set it up in the following manner select Oscillate, select No End, and use the parameters in parentheses by sliding the bars for Amplitude (1.00 cm), Frequency (2.40 Hz). Damping (none), and Tension (highest). Using the available Rulers, calculate the frequency of a photon that corresponds to the wavelength of the resulting wave. Assume the length with units (cm) of the ruler represents the real photon wavelength and that the speed of light is 3.00 x 10° m/s Express the frequency in hertz to two significant figures. > View Available Hint(s) ? frequency= Hz Submit Request Answer
