Problem 135

The rocket fuel hydrazine $\left(\mathrm{N}_{2} \mathrm{H}_{4}\right)$ is made by the three-step
Raschig process, which has the following overall equation:
$\mathrm{NaOCl}(a q)+2 \mathrm{NH}_{3}(a q) \longrightarrow \mathrm{N}_{2} \mathrm{H}_{4}(a q)+\mathrm{NaCl}(a q)+\mathrm{H}_{2} \mathrm{O}(l)$
What is the percent atom economy of this process?

Answer

29.4%

percent. Adam Economy is described as the massive Adams in the desired product, divided by the massive Adams in all reactive. So in this reaction, the desired product is hydrazine and to age for and are to reactant are these compounds here? So we simply use the periodic table to find the massive each Adam multiplying by any coefficients present to find the percent Adam economy. So we have in our product to nitrogen ins plus four hydrogen ins divided by one sodium plus one oxygen, plus the chlorine plus two nitrogen plus six hydrogen, which gives US 29.4% adam economy.
