Calculate the atom economy for the production of sulfur dioxide from sulfur burning: S + O2 ? SO2. (Use Ar: S = 32, O = 16.)
Which of the following best explains why atom economy is different from percentage yield?
Which of these design choices will almost always increase atom economy?
A reaction gives desired product mass 88 g and total product mass 112 g. What mass of waste is produced and what is the atom economy?
Which of the following is a correct statement linking atom economy and sustainability?
For the reaction Na2CO3 + 2HCl ? 2NaCl + CO2 + H2O, calculate the atom economy for the desired product 2NaCl. (Use Ar: Na = 23, C = 12, O = 16, Cl = 35.5.)
Which reaction has the higher atom economy for the desired product NH4NO3: A: NH3 + HNO3 ? NH4NO3 ; B: NH4Cl + AgNO3 ? NH4NO3 + AgCl ?
A chemist reports an atom economy of 95% for producing a fine chemical. Which of the following is a realistic implication?
For the reaction CaCO3 + 2HCl ? CaCl2 + CO2 + H2O, calculate the atom economy for the desired product CaCl2. (Use Ar: Ca = 40, C = 12, O = 16, Cl = 35.5.)
A synthesis route produces 2 g desired product and 6 g waste from a given amount of reactants. What is the atom economy for the desired product?
For the reaction: 2A ? desired product + B (where B is waste), a chemist increases atom economy by:
