Answer: a) is the limiting reagent
b) 3.59 g
c) 11.6g
Explanation:
To calculate the moles :
According to stoichiometry :
a) 9 moles of require= 4 moles of
Thus 0.15 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
b) As 9 moles of give = 8 moles of
Thus 0.15 moles of give =
of
Mass of
c) As 9 moles of give = 3 moles of
Thus 0.15 moles of give =
of
Mass of

days. I have attached an image on how to calculate half-life so you can plug
your give value into the formula.
