The [     ] is the maximum product mass calculated from the balanced equation.

A

The theoretical yield is the maximum product mass calculated from the balanced equation.

B

Atom economy is calculated using

atom economy=Mr of desired productsum of Mr of all products×100 \boxed{\text{atom economy} = \frac{M_r\text{ of desired product}}{\text{sum of }M_r\text{ of all products}} \times 100} atom economy=sum of Mr​ of all productsMr​ of desired product​×100​
C

4.485.60×100=\dfrac{4.48}{5.60} \times 100 = 5.604.48​×100= 80.0%80.0\%80.0%.

D

Much reactant mass becomes waste products.
