Chapter 8, Problem 41AE

(a)

Interpretation Introduction

Interpretation:

The products of decomposition reaction of zinc oxide have to be given along the balanced formula equation.

Concept Introduction:

Decomposition reactions:  Decomposition reactions are the opposite of a combination reaction because decomposition reaction involves the breaking apart of a substance into simpler substances.  Such a reaction is easy to recognize because there is one reactant and more than one product.

Example:  The reaction of sodium chlorate to sodium chloride and oxygen is decomposition reaction.  The balanced reaction is,

  ${\text{2NaClO}}_{\text{3}}\left(\text{s}\right)\stackrel{}{\to }\text{2NaCl}\left(\text{s}\right){\text{+3O}}_{\text{2}}\left(\text{g}\right)$
