Chapter 8, Problem 42AE

(a)

Interpretation Introduction

Interpretation:

The balanced equation and products for the reaction of magnesium metal with hydrochloric acid has to be written.

Concept Introduction:

Single displacement reactions:  A reaction where an element in a compound is replaced by another element is called single displacement reaction or a substitution reaction.  It generally involves between a dilute solution of an acid and a metal.

Example:  The product for the single displacement reaction of reaction of zinc and hydrogen bromide is zinc bromide and hydrogen.  The balanced reaction is,

  $\text{Zn}\left(\text{s}\right)\text{+2HBr}\left(\text{aq}\right)\stackrel{}{\to }{\text{ZnBr}}_{\text{2}}\left(\text{s}\right){\text{+H}}_{\text{2}}\left(\text{g}\right)$
