Biography

I earned my undergraduate degree in both Biology and Chemistry. I pursued and completed my Master's in Chemistry from the University of Rhode Island. I moved into High School teaching and Co-taught Biology/AP biology for 1 year, then I taught Physics for the next 3 years. I completed the training to teach AP Chemistry, but unfortunately, did not have enough students sign up to teach it at my latest school. I'm now trying to return to graduate school to pursue my PhD in Chemical Ecology.

The absorption spectrum of benzene dissolved in cyclohexane contains bands at 183,204 and $256 \mathrm{nm} .$ (a) Which band corresponds to the lowest energy transition? (b) Which band corresponds to the lowest wavenumber? (c) For $\lambda=256 \mathrm{nm}$ $\log \varepsilon=2.30 .$ Determine the concentration of a solution (path length $=1.00 \mathrm{cm}$ ) which gives an absorbance of 0.25.
