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

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

Chemistry is one branch of knowledge that grew from human curiosity about the world and has played a central role in the development of the modern world. Chemistry is the study of the composition of matter‚ the stuff things are made of‚ and the changes that matter undergoes. Now‚ we may not think chemistry plays such a big role in our life but it perhaps more than any other branch of science has bettered our lives. Almost anything we touch today has benefited from chemical technology‚ and there for
