(a)
Answer to Problem M.11E
Limiting reactant is identified as oxygen.
Explanation of Solution
First reaction in the formation of
From the balanced chemical equation it is found that
Number of moles of
Amount of oxygen required to react with phosphorus is calculated as follows:
It is found that the moles of oxygen that is supplied is more than the required for the phosphorus to react. Hence, oxygen is the reagent that is present in excess while
As
Therefore, the amount of
Second step in the formation of
The total moles of oxygen taken for the reaction is
The amount of oxygen that is required to react with
As the remaining amount of oxygen is lesser than the amount of oxygen that is required for the reaction to complete, the limiting reactant is found to be oxygen.

Interpretation:
Mass of
(b)
Answer to Problem M.11E
Mass of
Explanation of Solution
Reaction for the formation of
The total moles of oxygen taken for the reaction is
The mass of
Thus the mass of
(c)
Interpretation:
Mass of excess reactant that remains in the reaction has to be calculated.
(c)
Answer to Problem M.11E
Mass of unreacted excess reactant is
Explanation of Solution
Reaction in the formation of
The total moles of oxygen taken for the reaction is
The amount of oxygen that is required to react with
As the remaining amount of oxygen is lesser than the amount of oxygen that is required for the reaction to complete, the limiting reactant is found to be oxygen and the excess reagent is found to be
Moles of
Moles of
Mass of
Therefore, the mass of excess reactant that is unreacted is
