- Green Chemistry and Atom Economy The purposeful design of chemical products and processes that minimize the use of environmentally hazardous substances and the generation of waste is known as green chemistry. Green chemistry is a philosophical approach that is being applied to many areas of science and technology, and its practice is summarized by guidelines known as the “Twelve Principles of Green Chemistry” (see details at this website (http://openstaxcollege.org/l/16greenchem) ). One of the 12 principles is aimed specifically at maximizing the efficiency of processes for synthesizing chemical products. The atom economy of a process is a measureof this efficiency, defined as the percentage by mass of the final product of a synthesis relative to the masses of all the reactants used: atom economy = mass of product/mass of reactants × 100%Though the definition of atom economy at first glance appears very similar to that for percent yield, be aware that this property represents a…Green Chemistry and Atom Economy The purposeful design of chemical products and processes that minimize the use of environmentally hazardous substances and the generation of waste is known as green chemistry.

The current price of platinumis $26.89 per ounce. What is the range in cost of Pt in one catalytic converter?Archimedes, a famous Greek scientist, was given a problem by King Hieron II of Syracuse (Sicily). The king suspected that his crown, which was supposed to be made of pure gold, contained some silver alloy, and he asked Archimedes to prove or disprove his suspicion. (It turned out that the crown did not contain silver.) How would you experimentally determined whether or not the crown was pure gold? (Hint: The method came to Archimedes when getting into a full bathtub. See the footnote in Experiment 22 for Archimedes’ solution.)
