<u>538.73 g</u> is the mass of 5.85 mol of glycerol (C₃H₈O₃)
<h3>What is glycerol?</h3>
Glycerol is a simple polyol chemical, usually known as glycerine in British English and glycerin in American English. It is a sweet-tasting, colourless, odourless, viscous liquid that is non-toxic. Glycerides, a class of lipids, contain the glycerol backbone.
It is frequently utilised in FDA-approved wound and burn therapies due to its antibacterial and antiviral characteristics. On the other hand, it can also serve as a medium for bacterial cultivation. It can be used as a reliable indicator of liver illness.
Additionally, it is employed temporarily in the food sector as a sweetener and in drug formulations as a humectant. Glycerol is hygroscopic in nature and miscible with water due to its three primary hydroxyl groups.

Answer:
The answer to your question is a) N₂ b) 3.04 g of NH₃
Explanation:
Data
mass of H₂ = 2.5 g
mass of N₂ = 2.5 g
molar mass H₂ = 2.02 g
molar mass of N₂ = 28.02 g
molar mass of NH₃ = 17.04 g
Balanced chemical reaction
3H₂ + 1 N₂ ⇒ 2NH₃
A)
Calculate the theoretical yield 3H₂ / N₂ = 3(2.02) / 28.02 = 0.22
Calculate the experimental yield H₂/N₂ = 2.5/2.5 = 1
Conclusion
The limiting reactant is N₂ (nitrogen) because the experimental proportion was higher than the theoretical proportion.
B)
28.02 g of N₂ -------------------- (2 x 17.04) g of NH₃
2.5 g of N₂ -------------------- x
x = (2.5 x 2 x 17.04) / 28.02
x = 85.2 / 28.02
x = 3.04 g of NH₃
The answer is C) <span>The sample was broken down by the electric current and formed a new substance that could burn. Therefore, the original liquid is a compound. </span>
