Destiny Lipede The Chemistry of Hair Coloring: What are the effects of hair color on synthetic hair? The first thing that comes to mind when people see hair color is “beauty.” But‚ what most do not realize is that chemistry plays a major role in many everyday products. What makes the colors so pretty and attractive? How can hair color effect synthetic hair? The question I want to answer is “what are the effects of hair color on synthetic hair?” I chose this topic because I wanted to learn how

cocaine and has been identified as a likely candidate for the detection of concealed cocaine (Analytical Chemistry 1997). The second peak‚ which has a 15.67 retention time‚ has also five possible matches‚ (see appendix 1). From the peak report it can be said that the highest match for the unknown peak is cocaine‚ as it has the highest match of 934 and a reverse match of 946. Discussion GC is an analytical technique for separating compounds based on their volatilities. It both provide qualitative

John Abarshi Mr Meinsma Chemistry December 14‚ 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity‚ then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any type of solution‚ even ionic solutions‚ provide
