To determine the product of the reaction between arsenic (As) and oxygen (O), let's consider the possible oxides that arsenic forms with oxygen in typical chemical reactions.
Arsenic commonly reacts with oxygen to form arsenic oxides. These oxides often occur in various stoichiometries, such as:
1. Arsenic trioxide: [tex]$As_2O_3$[/tex]
2. Arsenic pentoxide: [tex]$As_2O_5$[/tex]
Among these, arsenic trioxide ([tex]$As_2O_3$[/tex]) is a common product when arsenic reacts with oxygen in typical conditions, as it forms during the combustion of arsenic in air.
Given the possible products listed in the options:
A. [tex]$As_3O_2$[/tex]
B. AsO
C. [tex]$As_2O_3$[/tex]
D. [tex]$AsO_2$[/tex]
Among these, [tex]$As_2O_3$[/tex] (option C) is the correct product formed when arsenic reacts with oxygen under normal conditions.
Thus, the correct answer is C. [tex]$As_2O_3$[/tex].
