Interpretation Introduction

(a)

Interpretation:

Classify the following as a combination, decomposition, single replacement, double replacement, or combustion reaction:

  ${\text{2Al}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{a}\right)\to \text{4Al}\left(\text{s}\right){\text{ + 3O}}_{\text{2}}\left(\text{g}\right)$

Concept Introduction:

Chemical reactions are of different types: In the combination reaction simple elements combine to form a complex compound.

In a combustion reaction a hydrocarbon burns in the presence of oxygen to form carbon dioxide and water vapor.

In the decomposition reaction a complex compound breaks into simple elements.

In single replacement reaction one element replaces another element in a compound.

In a double displacement reaction the cation of one ionic compound is replaced by the cation of another ionic compound. Similarly, the anion of one ionic compound is replaced by the anion of another ionic compound.
