Investigate Follow these steps to help the chemical company identify the gas leaking into the lab: 1. In the Emission Spectra tool, select each element to see its emission spectrum. 2. In the data table below, record the element symbol, atomic number, the lowest wavelength present in the spectrum (in nanometers), the highest wavelength in the spectrum (in nanometers), and the total number of lines in the spectrum. 3. Watch for any patterns in the spectra. For example, is there any correlation between an element's atomic number and the lowest or highest wavelength in its spectrum? Do larger elements consistently have more spectral lines? Collect Data Record data about the different emission spectra below.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
