WebbWe also learned about atom economy which is a way to measure atoms wasted when making a chemical. It measures the greenness of a process or synthesis. 3. Your instructor will give you the actual percent composition of NaHCO3 in the mixture. Webb1 jan. 2014 · The ideal atom economy for a chemical transformation is taken as the process where all reactant atoms are found in the desired product [ 1 ]. In other words, atom economy is a calculation which measures “how much of the reactants remain in the final product” [ 6 ].
WebbAtom Economy is the Mass of desired product/Sum of all masses (1) Therefore, a reaction with 100% yield could still have a low atom economy if a lot of the reactants end up as waste byproducts. (1) WebbSince all three H atoms of BH3 are used in the reaction, the theoretical atom economy is relatively high. Unfortunately, the experimental atom economy is not as high, because an excess of borane must be used. PRE-LAB QUESTIONS: 1.
