The limiting reactant in the reaction is the NO molecule.
<h3>What is limiting reactant?</h3>
The limiting reactant is the reactant that is present in the least amount in the reaction. The rate of reaction depends on the limiting reactant.
Given the reaction; 4NH3 + 6NO --> 5N2 + 6H2O.
Number of moles of NH3 = 43.4 g/17 g/mol = 2.55 moles
Number of moles of NO = 30 g/30 g/mol = 1 mole
Now if 4 moles of NH3 reacts with 6 moles of NO
2.55 moles of NH3 reacts with 2.55 moles * 6 moles/ 4 moles
= 3.8 moles
Hence, the limiting reactant in this reaction is NO.

Answer:
Final [B] = 1.665 M
Explanation:
3A + 4B → C + 2D
Average rection rate = 3[A]/Δt = 4[B]/Δt = [C]/Δt = 2[D]/Δt
0.05600 M/s = 4 [B]/ 2.50 s
[B] = 0.035 M (concentration of B consumed)
Final [B] = initial [B] - consumed [B]
Final [B] = 1.700 M - 0.035 M
Final [B] = 1.665 M
Density = mass divided by volume
Density = 8.2 divided by 24.5
Density = 0.33g/cm3
