Answer: 1. Oxygen is the the limiting reactant.
2. 7.52%
Step-by-step explanation:
The balanced chemical equation is:
To calculate the moles :


According to stoichiometry :
1 mole of
require = 2 moles of

Thus 0.165 moles of
will require=
of

Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
2.


As 2 moles of
give = 2 moles of

Thus 4.96 moles of
give =
of

percentage yield =

Thus the percent yield for the reaction is 7.52%
