Chapter 24, Problem 18QP

Interpretation Introduction

Interpretation:

The preparation of the given compounds, starting with ${\text{H}}_2$, is to be described.

Concept introduction:

The preparation of $\text{HCl}$ using ${\text{H}}_{\text{2}}$ as a reagent is an example of a combination reaction, in which two or more compounds combine to form a new compound.

Ammonia is prepared by the Haber’s process, in which hydrogen and nitrogen combine to give ammonia.

Lithium hydroxide cannot be prepared directly from hydrogen. It involves two steps that include the formation of lithium hydride, followed by the formation of lithium hydroxide.
