Question

The balanced equation for the experimental reaction is listed below. the desired product of this reaction is the solid silver chromate. calculate the atom economy of this reaction

Answer 1

The atom economy for the reaction forming silver dichromate from silver nitrate and potassium dichromate can be calculated using the molar masses and applying the atom economy formula. It reflects the efficiency of the reaction in terms of how much of the reactants end up in the desired product.

Step-by-step explanation:

The atom economy of a reaction is a measure of the efficiency of a chemical synthesis in terms of the proportion of the reactants that become part of the desired product. To calculate the atom economy, the formula is:

Atom Economy = (Molar mass of the desired product / Sum of molar masses of all products) * 100%

For the reaction between silver nitrate (AgNO3) and potassium dichromate (K2Cr2O7) to form solid silver dichromate (Ag2Cr2O7), the balanced equation is:

2 AgNO3 (aq) + K2Cr2O7 (aq) -> Ag2Cr2O7 (s)
Using the molar masses from the periodic table for each compound, calculate the numerator (molar mass of Ag2Cr2O7) and the denominator (sum of the molar masses of all reactants), and then apply the formula to determine the atom economy.
