Please answer 3 sub-units thank you!

Directions: Calculate the problem below.
The synthesis of urea, [(NH2)2CO, is considered to be the first recognized
example of preparing a biological compound from nonbiological
reactants, challenging the notion that biological processes involved a
“vital force" present only in living systems. Urea is also used in fertilizers
of the plants. Today urea is produced industrially by reacting ammonia
with carbon dioxide:
2NH3(g) + CO2(g) → (NH2)2CO(aq) + H2Oq)
In one process,
637.2 g
of NH3 are treated with 1142 g of CO2.
(a) Which of the two reactants is the limiting reagent?
(b) Calculate the mass of (NH2)2CO formed.
(c) How much excess reagent (in grams) is left at the end of the reaction?
