    of Green Chemistry. The American Chemical Society Green Chemistry Institute describes green chemistry as a different perspective on how chemistry and chemical engineering should be done to reduce waste, conserve energy, and utilize replacements for hazardous substances. Through a series of twelve principles, the ideals of Green Chemistry attempt to lessen the negative effects scientific innovation and utilization tend to have on our environment (Pavia, et al 2007). The term “Green Chemistry” was coined

    had long assumed the truth of the principle in general, the French chemist Joseph-Louis Proust first accumulated conclusive evidence for it in a series of researches on the composition of many substances, especially the oxides of iron (1797).  In chemistry, the law of definite proportions, sometimes called Proust's Law, states that achemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples
