Answer: 1.
is the limiting reagent and
is the excess reagent.
2. 2.91 g of excess reagent
3. 4.66 g of carbon dioxide produced.
Step-by-step explanation:
To calculate the moles :
According to stoichiometry :
2 moles of
require = 1 mole of
Thus 0.106 moles of
will require=
of
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
Amount of excess reagent = ( 0.144-0.053) moles = 0.091 moles
Mass of excess reagent
As 2 moles of
give = 2 moles of
Thus 0.106 moles of
give =
of
Mass of
