Answer:
a) 
b)
is the limiting reagent
c) Moles of
produced = 2.45 mol
b) Moles of
left = 1.75 -1.22 = 0.53
Explanation:
a) Balanced reaction:

b)
No. of mole of 
No. of mole of 

As, it is clear from the reaction that,
1 mol of
requires 3 moles of 
1.75 mol of
require = 1.75 × 3 = 5.25 mol of 
As, only 3.68 mol of
is present, so
is the limiting reagent.
c)
3 moles of
form 2 moles of 
3.68 moles of
will form = 
d)
is present in excess.
3 moles of
requires 1 mol of 
3.68 moles of
will require = 
left = 1.75 -1.22 = 0.53 mol
