Reactant C is the limiting reactant in this scenario.
Explanation:
The reactant in the balanced chemical reaction which gives the smaller amount or moles of product is the limiting reagent.
Balanced chemical reaction is:
A + 2B + 3C → 2D + E
number of moles
A = 0.50 mole
B = 0.60 moles
C = 0.90 moles
Taking A as the reactant
1 mole of A reacted to form 2 moles of D
0.50 moles of A will produce 
= 
thus 0.50 moles of A will produce 1 mole of D
Taking B as the reactant
2 moles of B reacted to form 2 moles of D
0.60 moles of B reacted to form x moles of D
= 
x = 2 moles of D is produced.
Taking C as the reactant:
3 moles of C reacted to form 2 moles of D
O.9 moles of C reacted to form x moles of D
= 
= 0.60 moles of D is formed.
Thus C is the limiting reagent in the given reaction as it produces smallest mass of product.
There chemical reactions that can realise or absorb gas to the atmosphere. This means it is harder or impossible to measure it with normal weighing devices and normal taring equipment. As a principal in chemical reactions we have conservation of mass.

Answer:
A inhibitor structure resembles substrate structure B inhibitor binds non covalently at site other than active site.C inhibitors bind covalently and permanently at active site.
Explanation:
A Reversible competitive inhibitors structurally resembles the substrate and competes with the substrate to bind to the active site of the target enzyme.
B Reversible noncompetitive inhibitors binds no covalently at site of the target enzyme that is different from the active site.
C irreversible inhibitors interacts very tightly to the active site of an enzyme by covalent bond which cannot be overcome.
