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…

2. The goal behind suction filtration is to remove soluble impurities that are on the surface of the crystals. Therefore, why can't you simply use suction filtration instead of recrystallization to purify an impure solid?

Gas chromatography is an analytical technique that is used to separate and analyze samples that can be vaporized without decomposing. The chromatography column contains a substance that helps separate the sample being analyzed. The sample is vaporized and carried through the column by an inert gas. As the mixture moves through the column, the compounds are separated based on how much they interact with the substance in the column. The molecules of each compound are detected as they exit the column, and a peak for each compound is produced on a chromatogram. The area under each peak on the chromatogram is proportional to the concentration of the compound in the sample. A chromatogram produced by separating a mixture of compounds is shown. Time to Go Through Column Based on the information given, which of the following statements about the chromatogram is most likely true? A The three peaks each represent a different element. B The three peaks each represent a different substance used to…

Q29 Santa Monica Big Blue Bus operates a fleet of CNG buses, which run on compressed natural gas (CNG), natural gas that has been compressed into a much smaller volume in the fuel tank. A newly designed CNG vehicle carries about several thousand cubic feet of compressed natural gas which contain 72 kg (kilograms) of carbon. If all of the natural gas is burned, how many kilograms of carbon dioxide will be emitted into the atmosphere? Assume no residue remains and the carbon dioxide is the only product in the combustion. If you are presenting this question, please explain the following: The steps in the calculation process O Please write out the steps involved in the conversion process including the units O Please explain how to operate on the units Please explain how to manipulate the powers of ten by hand (e.g. product rule and the quotient rule) How to apply the appropriate rule to the calculation: O addition-subtraction rule ("the decimal places rule"), OR multiplication-division…

The mass of magnesium used in this experiment is critical to determining the moles of hydrogen gas generated. The analytical balances used in Chemistry 1A labs are very sensitive to point that touching materials with your fingers before measuring them can affect the measurements. The balances are sensitive enough to detect dirt and oils from your fingers transferred to the magnesium. Would your experimental value of R increase or decrease if the mass of magnesium measured was artificially high due the touching it with your hands? Increase Decrease

Natural way of food preservation has been part of the Filipino cuisine and food culture, this enables Filipino families to store food for future consumption and for "flavor enhancement". However, since these preservation methods are done naturally (without preservative) the tendency of food spoilage is very high, and this has been a big concern in Natural Food Preservation. Now as a Filipino student, what proposition would you suggest in fixing this concern? And Which concept in General Chemistry II can be best applied to understand this phenomenon? 5.
