QUESTION 7

The formation of sulfur trioxide [tex]$\left( SO_3 \right)$[/tex] is represented by the following balanced equation:

[tex]$
2 SO_2(g) + O_2(g) \rightarrow 2 SO_3(g)
$[/tex]

7.1 Identify the elements in the above equation.

7.2 Draw the Lewis dot diagram of the oxygen molecule [tex]$\left( O_2 \right)$[/tex].

7.3 During the above reaction, [tex]$10 \, g$[/tex] of [tex]$O_2$[/tex] (oxygen) reacts completely with sulfur dioxide [tex]$\left( SO_2 \right)$[/tex]. Calculate the:

7.3.1 Number of moles of [tex]$O_2$[/tex] reacted

7.3.2 Theoretical yield of [tex]$SO_3(g)$[/tex]

7.3.3 Percentage yield if [tex]$40 \, g$[/tex] of [tex]$SO_3$[/tex] is produced at the end of the reaction.
