Chapter 4, Problem 35E

Write balanced chemical equations for the reactions used to prepare each of the following compounds from the given starting material(s). In some cases, additional reactants may be required.

(a) solid ammonium nitrate from gaseous molecular nitrogen via a two-step process (first reduce the nitrogen to ammonia, then neutralize the ammonia with an appropriate acid)

(b) gaseous hydrogen bromide from liquid molecular bromine via a one-step redox reaction

(c) gaseous ${\text{H}}_2\text{S}$ from solid Zn and S via a two-step process (first a redox reaction between the starting materials, then reaction of the product with a strong acid)
