Chapter 4, Problem 131IAE

The industrial productionof hydrazine $\left({\text{N}}_{\text{2}}{\text{H}}_{\text{2}}\right)$ by the Ranching process is the topic of the Focus On feature for Chapter 4 on www.masteringchemistry.com. The following chemical equation represents the overall process, which actually involves three consecutive reasons.

${\text{2NH}}_{\text{3}}\left(\text{aq}\right){\text{+CI}}_{\text{2}}\left(\text{g}\right)\text{+2NaOH}\left(\text{aq}\right){\text{®N}}_{\text{2}}{\text{H}}_{\text{4}}\left(\text{aq}\right)\text{+2NaCI}\left(\text{aq}\right){\text{+2H}}_{\text{2}}\text{O}\left(\text{1}\right)$

a. Use the definition of percent atom economy (AE) from exercise 130 to calculate, to the nearest percent, the percent AE for the Ranching process.
b. Propose a reaction for the synthesis of ${\text{N}}_{\text{2}}{\text{H}}_{\text{4}}$ that has AE of 100%.
